Introduction 1 In This Chapter The following topics are covered in this section: • • • • Document Conventions Introduction to Wireless Networking IEEE 802.11 Specifications Management and Monitoring Capabilities Document Conventions • The term, AP, refers to an Access Point. • The term, 802.11, is used to describe features that apply to the 802.11a, 802.11b, and 802.11g wireless standards.
Introduction to Wireless Networking standard. • Blue text indicates a link to a topic or Web address. If you are viewing this documentation on your computer, click the blue text to jump to the linked item. NOTE: A Note indicates important information that helps you make better use of your computer. ! CAUTION: A Caution indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
Introduction to Wireless Networking Site Survey To determine the best location for an Access Point, Avaya recommends conducting a Site Survey before placing the device in its final location. For information about how to conduct a Site Survey, contact your local reseller. Before an Access Point can be configured for your specific networking requirements, it must first be initialized. See Getting Started for details. Figure 1-1.
Introduction to Wireless Networking Once initialized, the network administrator can configure each unit according to the network’s requirements. The AP functions as a wireless network access point to data networks. An AP network provides: • • • • Seamless client roaming Easy installation and operation Over-the-air encryption of data High speed network links To be fully operational, the AP-3 needs at least one wireless card installed.
Introduction to Wireless Networking Network Names • All Access Points must have the same Network Name to support client roaming. • All workstations with an 802.11 client adapter installed must use either a Network Name of “any” or the same Network Name as the Access Points that they will roam between. If an AP has Closed System enabled, a client must have the same Network Name as the Access Point to communicate (see Interfaces).
IEEE 802.11 Specifications Data Rates An 802.11a or 802.11b/g AP operates at faster data rates than the 802.11b AP. 802.11a and 802.11g products operate at speeds of up to 54 Mbits/sec; 802.11b products operate at speeds of up to 11 Mbits/sec. Channels • All Access Points in the same vicinity should use a unique, independent Channel. By default, the AP automatically scans for available Channels during boot-up but you can also set the Channel manually (see Interfaces for details).
IEEE 802.11 Specifications 802.11b In 1999, the IEEE modified the 802.11 standard to support direct sequence devices that can operate at speeds of up to 11 Mbits/sec. The IEEE ratified this standard as 802.11b. 802.11b devices are backwards compatible with 2.4 GHz 802.11 direct sequence devices (that operate at 1 or 2 Mbits/sec). Available Frequency Channels vary by regulatory domain and/or country. See 802.11b Channel Frequencies for details. 802.11a Also in 1999, the IEEE modified the 802.
Management and Monitoring Capabilities Management and Monitoring Capabilities There are three management and monitoring interfaces available to the network administrator to configure and manage an AP on the network: • HTTP Interface • Command Line Interface • SNMP Management HTTP Interface The HTTP Interface (also known as the Web browser Interface) provides easy access to configuration settings and network statistics from any computer on the network.
Management and Monitoring Capabilities Users enter Command Statements, composed of CLI Commands and their associated parameters. Statements may be issued from the keyboard for real time control, or from scripts that automate configuration. For example, when downloading a file, administrators enter the download CLI Command along with IP Address, file name, and file type parameters. How To Access the CLI You access the CLI over a HyperTerminal serial connection or via Telnet.
Management and Monitoring Capabilities SNMP Management You can also manage and configure an AP using the Simple Network Management Protocol (SNMP). NOTE: This requires an SNMP manager program, like HP Openview or Castlerock’s SNMPc. The AP supports several Management Information Base (MIB) files that describe the parameters that can be viewed and/or configured over SNMP: • • • • • MIB-II (RFC 1213) Bridge MIB (RFC 1493) Ethernet-like MIB (RFC 1643) 802.
Management and Monitoring Capabilities The Enterprise MIB defines the read and read-write objects that can be viewed or configured using SNMP. These objects correspond to most of the settings and statistics that are available with the other management interfaces. Refer to the Enterprise MIB for more information; the MIB can be opened with any text editor, such as Microsoft Word, Notepad, or WordPad.
Getting Started 2 In This Chapter • • • • • • • Prerequisites Product Package System Requirements Hardware Installation Initialization Download the Latest Software Additional Hardware Features Prerequisites Before installing an AP, you need to gather certain network information. The following section identifies the information you need.
Prerequisites Network Name (SSID of the wireless cards) Assign the Access Point a Network Name before wireless users can communicate with it. The clients also need the same Network Name. This is not the same as the System Name, which applies only to the Access Point. The network administrator typically provides the Network Name. AP’s IP Address If you do not have a DHCP server on your network, then you need to assign the Access Point an IP address that is valid on your network.
Prerequisites Authentication Method A primary authentication server may be configured; a backup authentication server is optional. The network administrator typically provides this information. Authentication Server Shared Secret This is a password shared between the Access Point and the RADIUS authentication server (so both passwords must be the same), and is typically provided by the network administrator.
Product Package Product Package Each Dual-radio AP comes with the following: • • • • • • • • • One ceiling or wall mounting plate Mounting hardware Metal faceplate for APs mounted in a plenum environment AP cover Processor module (with integrated Active Ethernet, if applicable) Power supply (not provided with Active Ethernet unit) AC power cord (not provided with Active Ethernet unit) 802.11b PC Card or 802.
System Requirements 5 GHz Antenna Adapter or AP-3 11a Upgrade Kit The 5 GHz Antenna Adapter or 11a Upgrade Kit (used with software release 2.3) can be used in the Access Point.

Initialization Initialization Avaya provides two tools to simplify the initialization and configuration of an AP: • ScanTool • Setup Wizard ScanTool is included on the Installation CD; the Setup Wizard launches automatically the first time you access the HTTP interface. NOTE: These initialization instructions describe how to configure an AP over an Ethernet connection using ScanTool and the HTTP interface.
Initialization ScanTool ScanTool is a software utility that is included on the installation CD-ROM. The tool automatically • detects the Access Points installed on your network, regardless of IP address, • lets you configure each unit’s IP settings, and • allows you to download new software to an AP that does not have a valid software image installed (see Client Connection Problems).
Initialization 1. Locate the unit’s Ethernet MAC address and write it down for future reference. The MAC address is printed on the product label. Each unit has a unique MAC address, which is assigned at the factory. 2. Confirm that the AP is connected to the same LAN subnet as the computer that you will use to configure the AP. 3. Power up, reboot, or reset the AP. — Result: The unit requests an IP Address from the network DHCP server. 4.
Initialization — Result: ScanTool scans the subnet and displays all detected Access Points. The ScanTool’s Scan List screen appears, as shown in the following example. NOTE: If your computer has more than one network adapter installed, you will be prompted to select the adapter that you want ScanTool to use before the Scan List appears. If prompted, select an adapter and click OK. You can change your adapter setting at any time by clicking the Select Adapter button on the Scan List screen.
Initialization NOTE: If your Access Point does not show up in the Scan List, click the Rescan button to update the display. If the unit still does not appear in the list, see Troubleshooting for suggestions. Note that after rebooting an Access Point, it may take up to five minutes for the unit to appear in the Scan List.
Initialization 8. Do one of the following: — If the AP has been assigned an IP address by a DHCP server on the network, write down the IP address and click Cancel to close ScanTool. Go to Setup Wizard for information on how to access the HTTP interface using this IP address. — If the AP has not been assigned an IP address (in other words, the unit is using its default IP address, 10.0.0.
Initialization Step Action 1. Highlight the entry for the AP you want to configure. 2. Click the Change button. Result: The Change screen appears. Figure 2-14.
Initialization Step Action 3. Set IP Address Type to Static. 4. Enter a static IP Address for the AP in the field provided. You must assign the unit a unique address that is valid on your IP subnet. Contact your network administrator if you need assistance selecting an IP address for the unit. 5. Enter your network’s Subnet Mask in the field provided. 6. Enter your network’s Gateway IP Address in the field provided. 7.
Initialization Step 8. Action Click OK to save your changes. Result: The Access Point will reboot automatically and any changes you made will take effect. 9. When prompted, click OK a second time to return to the Scan List screen. 10. Click Cancel to close the ScanTool. 11. Proceed to Setup Wizard for information on how to access the HTTP interface.
Initialization Setup Wizard The first time you connect to an AP’s HTTP interface, the Setup Wizard launches automatically. The Setup Wizard provides step-by-step instructions for how to configure the Access Point’s basic operating parameter, such as Network Name, IP parameters, system parameters, and management passwords. Setup Wizard Instructions Follow these steps to access the Access Point’s HTTP interface and launch the Setup Wizard: 1. Open a Web browser on a network computer.
Initialization e. Click OK twice to save your changes and return to Internet Explorer. 3. Enter the Access Point’s IP address in the browser’s Address field and press Enter. This is either the — dynamic IP address assigned by a network DHCP server or — the static IP address you manually configured.

Location The location where the AP is installed. Contact Name The name of the person responsible for the AP. Contact Email The email address of the person responsible for the AP. Contact Phone The telephone number of the person responsible for the AP.
Network Parameters Description Descriptor This is a read-only field that reports the Access Point’s name, serial number, current image software version, and current bootloader software version. Up Time This is a read-only field that displays how long the Access Point has been running since its last reboot. Network The Network category contains three sub-categories.
Network Basic IP Parameters Parameter 4-8 Description IP Address Assignment Type Set this parameter to Dynamic to configure the Access Point as a Dynamic Host Configuration Protocol (DHCP) client; the Access Point will obtain IP settings from a network DHCP server automatically during boot-up. If you do not have a DHCP server or if you want to manually configure the Access Point’s IP settings, set this parameter to Static. IP Address The Access Point’s IP address.
Network Parameter Description Subnet Mask The Access Point’s subnet mask. When IP Address Assignment Type is set to Dynamic, this field is read-only and reports the unit’s current subnet mask. The subnet mask will default to 255.0.0.0 if the unit cannot obtain one from a DHCP server. Gateway IP Address The IP address of the Access Point’s gateway. When IP Address Assignment Type is set to Dynamic, this field is read-only and reports the IP address of the unit’s gateway.
Network DNS Client If you prefer to use host names to identify network servers rather than IP addresses, you can configure the AP to act as a Domain Name Service (DNS) client. When this feature is enabled, the Access Point contacts the network’s DNS server to translate a host name to the appropriate network IP address. You can use this DNS Client functionality to identify RADIUS servers by host name. See RADIUS for details.
Network Parameter Description DNS Secondary Server IP Address The IP address of a second DNS server on the network. The Access Point will attempt to contact the secondary server if the primary server is unavailable. DNS Client Default Domain Name The default domain name for the Access Point’s network (for example, “avaya.com”). Contact your network administrator if you need assistance setting this parameter.
Network Advanced Default TTL (Time to Live): Time to Live (TTL) is a field in an IP packet that specifies how long in seconds the packet can remain active on the network. The Access Point uses the default TTL for packets it generates for which the transport layer protocol does not specify a TTL value. This parameter supports a range from 0 to 65535. By default, TTL is 64.
Network Figure 4-3.
Network You can configure and view the following parameters within the DHCP Server Configuration screen: Parameter Enable DHCP Server Description Place a check mark in the box provided to enable DHCP Server functionality. NOTE: You cannot enable the DHCP Server functionality unless there is at least one IP Pool Table Entry configured. Subnet Mask This field is read-only and reports the Access Point’s current subnet mask.
Network Parameter IP Pool Table Entry Description This entry specifies a range of IP addresses that the AP can assign to its wireless clients. Click Add to create a new entry. Click Edit to change an existing entry. Each entry contains the following field: • Start IP Address • End IP Address • Default Lease Time (optional): The default time value for clients to retain the assigned IP address. DHCP automatically renews IP Addresses without client notification.
Network Parameter IP Pool Table Entry (continued) Description Status: IP Pools are enabled upon entry in the table. You can also disable or delete entries by changing this field’s value. NOTE: You must reboot the Access Point before changes to any of these DHCP server parameters take effect Link Integrity The Link Integrity feature checks the link between the AP and the nodes on the Ethernet backbone. These nodes are listed by IP address in the Link Integrity IP Address Table.
Network You can configure and view the following parameters within the Link Integrity Configuration screen: Parameter Description Enable Link Integrity Place a check mark in the box provided to enable Link Integrity. Poll Interval (milliseconds) The interval between link integrity checks. Range is 500 - 15000 ms in increments of 500 ms; default is 500 ms. Poll Retransmissions The number of times a poll should be retransmitted before the link is considered down. Range is 0 to 255; default is 5.

Interfaces Interfaces From the Interfaces tab, you configure the Access Point’s radio and Ethernet settings. Refer to the Wireless parameters below that correspond to your radio type. • Wireless (802.11a) • Wireless (802.11b) • Wireless (802.11b/g) • Ethernet Wireless (802.11a) You can configure and view the following parameters within the Wireless Interface Configuration screen for an 802.
Interfaces NOTE: You must reboot the Access Point before any changes to these parameters take effect. Parameter Description Physical Interface Type For an 802.11a AP, this field reports: “802.11a (OFDM 5 GHz).” OFDM stands for Orthogonal Frequency Division Multiplexing; this is the name for the radio technology used by 802.11a devices. MAC Address This is a read-only field that displays the unique MAC (Media Access Control) address for the Access Point’s wireless interface.
Interfaces Parameter Regulatory Domain Description Reports the regulatory domain for which the AP is certified. Not all features or channels are available in all countries. The available regulatory domains include: • FCC - U.S./Canada, Mexico, and Australia • ETSI - Europe and the United Kingdom • MKK: Japan • SG: Singapore • ASIA: China, Hong Kong, and South Korea • TW: Taiwan Network Name (SSID) Enter a Network Name (between 1 and 32 characters long) for the wireless network.
Interfaces Parameter Description Auto Channel Select The AP scans the area for other Access Points and selects a free or relatively unused communication channel. This helps prevent interference problems and increases network performance. By default this feature is enabled. Note that you cannot disable Auto Channel Select for 802.11a products in Europe (see Dynamic Frequency Selection (DFS) for details). See 802.11a Channel Frequencies for a list of Channels.
Interfaces Parameter Description Transmit Rate Use the drop-down menu to select a specific transmit rate for the AP. Choose between 6, 9, 12, 18, 24, 36, 48, 54 Mbits/s, and Auto Fallback. Auto Fallback is the default setting; it allows the AP unit to select the best transmit rate based on the cell size. DTIM Period The Deferred Traffic Indicator Map (DTIM) is used with clients that have power management enabled.
Interfaces Parameter Description RTS/CTS Medium Reservation This parameter affects message flow control and should not be changed under normal circumstances. Range is 0 to 2347. When set to a value between 0 and 2347, the Access Point uses the RTS/CTS mechanism for packets that are the specified size or greater. When set to 2347 (the default setting), RTS/CTS is disabled. See RTS/CTS Medium Reservation for more information.
Interfaces DFS only applies to 802.11a APs used in Europe (i.e., units whose regulatory domain is set to ETSI). The European Telecommunications Standard Institute (ETSI) requires that 802.11a devices use DFS to prevent interference with radar systems and other devices that already occupy the 5 GHz band. If you are using an 802.11a AP in Europe, keep in mind the following: • DFS is not a configurable parameter. It is always enabled and cannot be disabled.
Interfaces When RTS/CTS occurs, the following occurs. 1. The sending radio first transmits a Request to Send (RTS) packet to confirm that the medium is clear. 2. When the receiving radio successfully receives the RTS packet, it transmits back a Clear to Send (CTS) packet to the sending radio. 3. When the sending radio receives the CTS packet, it sends the data packet to the receiving radio.
Interfaces Wireless (802.11b) You can configure and view the following parameters within the Wireless Interface Configuration screen for an 802.11b AP: NOTE: You must reboot the Access Point before any changes to these parameters take effect. Parameter Description Physical Interface Type For 802.11b AP, this field reports: “802.11b (DSSS 2.4 GHz).” DSSS stands for Direct Sequence Spread Spectrum; this is the name for the radio technology used by 802.11b devices.
Interfaces Parameter Regulatory Domain Description Reports the regulatory domain for which the AP is certified. Not all features or channels are available in all countries. The available regulatory domains include: • FCC - U.S./Canada, Mexico, and Australia • ETSI - Most of Europe, including the United Kingdom, Ireland, Singapore, and Hong Kong • MKK: Japan • IL - Israel Network Name (SSID) 4-28 Enter a Network Name (between 1 and 32 characters long) for the wireless network.
Interfaces Parameter Description Auto Channel Select The AP scans the area for other Access Points and selects a free or relatively unused communication channel. This helps prevent interference problems and increases network performance. By default this feature is enabled; see 802.11b Channel Frequencies for a list of Channels. However, if you are setting up a Wireless Distribution System (WDS), it must be disabled. See Wireless Distribution System (WDS) for more information.
Interfaces Parameter Distance Between APs 4-30 Description Set to Large, Medium, Small, Microcell, or Minicell depending on the site survey for your system. By default, this parameter is set to Large. The distance value is related to the Multicast Rate (described next). In general, a larger distance between APs means that your clients operate a slower data rates (on average). See Distance Between APs for more information.
Interfaces Parameter Multicast Rate Description Sets the rate at which Multicast messages are sent. This value is related to the Distance Between APs parameter (described previously). The table below displays the possible Multicast Rates based on the Distance between APs setting. By default, this parameter is set to 2 Mbits/sec. See Multicast Rate for more information. Avaya Wireless AP-3 User’s Guide Distance between APs Multicast Rate Large 1 and 2 Mbits/sec Medium 1, 2, and 5.
Interfaces Parameter Description DTIM Period The Deferred Traffic Indicator Map (DTIM) is used with clients that have power management enabled. DTIM should be left at 1, the default value, if any clients have power management enabled. This parameter supports a range between 1 and 255. RTS/CTS Medium Reservation This parameter affects message flow control and should not be changed under normal circumstances. Range is 0 to 2347.
Interfaces Parameter Description Interference Robustness Enable this option if other electrical devices in the 2.4 GHz frequency band (such as a microwave oven or a cordless phone) may be interfering with the wireless signal. The AP will automatically fragment large packets into multiple smaller packets when interference is detected to increase the likelihood that the messages will be received in the presence of interference.
Interfaces Parameter Description Load Balancing Enable this option so clients can evaluate which Access Point to associate with, based on current AP loads. This feature is enabled by default; it helps distribute the wireless load between APs. This feature is not available if you are using an Avaya 802.11a/b Card or a non-Avaya Wireless client with the AP.
Interfaces Distance Between APs Distance Between APs defines how far apart (physically) your AP devices are located, which in turn determines the size of your cell. Cells of different sizes have different capacities and, therefore, suit different applications. For instance, a typical office has many stations that require high bandwidth for complex, high-speed data processing. In contrast, a typical warehouse has a few forklifts requiring low bandwidth for simple transactions.
Interfaces Coverage The number of Access Points in a set area determines the network coverage for that area. A large number of Access Points covering a small area is a high-density cell. A few Access Points, or even a single unit, covering the same small area would result in a low-density cell, even though in both cases the actual area did not change — only the number of Access Points covering the area changed.
Interfaces Figure 4-5. Low Density vs. Ultra High Density Network The Distance Between Cells parameter supports five values: Large, Medium, Small, Minicell, and Microcell. ! CAUTION: The distance between APs should not be approximated. It is calculated by means of a manual Site Survey, in which an AP is set up and clients are tested throughout the area to determine signal strength and coverage, and local limits such as physical interference are investigated.
Interfaces Multicast Rate The multicast rate determines the rate at which broadcast and multicast packets are transmitted by the Access Point to the wireless network. Stations that are closer to the Access Point can receive multicast packets at a faster data rate than stations that are farther away from the AP. You should set the Multicast Rate based on the size of the Access Point’s cell.
Interfaces Figure 4-6. 1 Mbits/s and 11 Mbits/s Multicast Rates NOTE: There is an inter-dependent relationship between the Distance between APs and the Multicast Rate. In general, larger systems operate at a lower average transmit rate.
Interfaces Large Medium Small Minicell Microcell 1.0 Mbit/s yes yes yes yes yes 2.0 Mbits/s yes yes yes yes yes 5.5 Mbits/s yes yes yes yes 11 Mbits/s yes yes yes The Distance Between APs must be set before the Multicast Rate, because when you select the Distance Between APs, the appropriate range of Multicast values automatically populates the drop-down menu. Wireless Distribution System (WDS) A Wireless Distribution System (WDS) creates a link between two 802.11b APs over their radio interfaces.
Interfaces NOTE: This feature is not available with an 802.11a or 802.11b/g AP. Figure 4-7.
Interfaces Bridging WDS Each WDS link is mapped to a logical WDS port on the 802.11b AP. WDS ports behave like Ethernet ports rather than like standard wireless interfaces: on a BSS port, an Access Point learns by association and from frames; on a WDS or Ethernet port, an Access Point learns from frames only. When setting up a WDS, keep in mind the following: Communication Bandwidth: The WDS link shares the communication bandwidth with the clients.
Interfaces Spanning Tree: If your network does not support spanning tree, be careful to avoid creating network loops between APs. For example, creating a WDS link between two Access Points connected to the same Ethernet network will create a network loop (if spanning tree is disabled). WDS Setup Procedure NOTE: You must disable Auto Channel Select to create a WDS. To setup a wireless backbone follow the steps below for each 802.11b AP that you wish to include in the Wireless Distribution System. 1.
Interfaces Figure 4-8. WDS Configuration NOTE: To set up a Wireless Distribution System (WDS) with 802.1x, set each Access Point’s 802.1x Security Mode to Mixed and assign each unit in the WDS the same Encryption Key 1. See Security.
Interfaces Wireless (802.11b/g) You can configure the following radio parameters for an 802.11b/g AP: NOTE: You must reboot the Access Point before any changes to these parameters take effect.
Interfaces Parameter Operational Mode Description An 802.11b/g wireless interface can be configured to operate in the following modes: • 802.11b mode only: The radio uses the 802.11b standard only. • 802.11g mode only: The radio is optimized to communicate with 802.11g devices. This setting will provide the best results if this radio interface will only communicate with 802.11g devices. • 802.11bg mode: This is the default mode. Use this mode if you want to support a mix of 802.11b and 802.11g devices.
Interfaces Parameter Physical Interface Type Description Depending on the Operational Mode, this field reports: • For 802.11b mode only: "802.11b (CCK/DSSS 2.4 GHz)" • For 802.11g and 802.11g-wifi modes: "802.11g (OFDM/DSSS 2.4 GHz)" • For 802.11bg mode: "802.11b/g (ERP-CCK/DSSS/OFDM 2.4 GHz)" OFDM stands for Orthogonal Frequency Division Multiplexing; this is the name for the radio technology used by 802.11a devices.
Interfaces Parameter Regulatory Domain Description Reports the regulatory domain for which the AP is certified. Not all features or channels are available in all countries. The available regulatory domains include: • FCC - U.S./Canada, Mexico, and Australia • ETSI - Europe, including the United Kingdom, China, and South Korea • MKK - Japan • IL - Israel Network Name (SSID) Enter a Network Name (between 1 and 32 characters long) for the wireless network.
Interfaces Parameter Description Frequency Channel When Auto Channel Select is enabled, this field is read-only and displays the Access Point’s current operating channel. When Auto Channel Select is disabled, you can specify the Access Point’s operating channel. If you decide to manually set the unit’s channel, ensure that nearby devices do not use the same frequency (unless you are setting up a WDS). Available Channels vary based on regulatory domain. See 802.11g Channel Frequencies.
Interfaces Parameter Description DTIM Period The Deferred Traffic Indicator Map (DTIM) is used with clients that have power management enabled. DTIM should be left at 1, the default value, if any clients have power management enabled. This parameter supports a range between 1 and 255. RTS/CTS Medium Reservation This parameter affects message flow control and should not be changed under normal circumstances. Range is 0 to 2347.
Interfaces Ethernet Select the desired speed and transmission mode from the drop-down menu. Half-duplex means that only one side can transmit at a time and full-duplex allows both sides to transmit. When set to auto-duplex, the AP negotiates with its switch or hub to automatically select the highest throughput option supported by both sides.
Management Management The Management category contains three sub-categories. • Passwords • IP Access Table • Services Passwords You can configure the following passwords: Type Description SNMP Read Password For read access to the AP using SNMP. Enter a password in both the Password field and the Confirm field. The default password is “public”. SNMP Read/Write Password For read and write access to the AP using SNMP. Enter a password in both the Password field and the Confirm field.
Management Type Description HTTP (Web) Password For the Web browser HTTP interface. Enter a password in both the Password field and the Confirm field. The default password is “public”. NOTE: For security purposes Avaya recommends changing ALL PASSWORDS from the default “public” immediately, to restrict access to your network devices to authorized personnel. If you lose or forget your password settings, you can always perform the Reset to Factory Default Procedure.
Management — The IP mask 255.255.255.255 would authorize the single station defined by the IP Address to configure the Access Point. The AP would ignore commands from any other IP address. In contrast, the IP mask 255.255.255.0 would allow any device that shares the first three octets of the IP address to configure the AP. For example, if you enter an IP address of 10.20.30.1 with a 255.255.255.0 subnet mask, any IP address between 10.20.30.1 and 10.20.30.
Management Services You can configure the following management services: NOTE: You must reboot the Access Point if you change the HTTP Port or Telnet Port.
Management SNMP Settings Setting SNMP Interface Bitmask Description Configure the interface or interfaces (Ethernet, Wireless, All Interfaces) from which you will manage the AP via SNMP. You can also select Disabled to prevent a user from accessing the AP via SNMP. HTTP Access Setting HTTP Interface Bitmap 4-56 Description Configure the interface or interfaces (Ethernet, Wireless, All Interfaces) from which you will manage the AP via the Web interface.
Management Setting Description HTTP Port Configure the HTTP port from which you will manage the AP via the Web interface. By default, the HTTP port is 80. Enable HTTP Setup Wizard The Setup Wizard appears automatically the first time you access the HTTP interface. If you exited out of the Setup Wizard and want to relaunch it, enable this option, click OK, and then close your browser or reboot the AP. The Setup Wizard will appear the next time you access the HTTP interface.
Management Figure 4-9.
Management Telnet Configuration Settings Setting Description Telnet Interface Bitmask Select the interface (Ethernet, Wireless, All Interfaces) from which you can manage the AP via telnet. This parameter can also be used to Disable telnet management. Telnet Port The default port number for Telnet applications is 23. However, you can use this field if you want to change the Telnet port for security reasons (but your Telnet application also must support the new port number you select).
Management Serial Configuration Settings The serial port interface on the AP is enabled at all times. See Setting IP Address using Serial Port for information on how to access the CLI interface via the serial port. You can configure and view following parameters: Setting Description Baud Rate Select the serial port speed (bits per second). Choose between 2400, 4800, 9600, 19200, 38400, or 57600; the default Baud Rate is 9600.
Filtering Setting Description Serial Parity This is a read-only field and displays the number of parity bits used in serial communication (no parity bits by default). Serial Stop Bits This is a read-only field that displays the number of stop bits used in serial communication (1 stop bit by default). NOTE: The serial port bit configuration is commonly referred to as 8N1.
Filtering Ethernet Protocol The Ethernet Protocol Filter blocks or forwards packets based on the Ethernet protocols they support. Follow these steps to configure the Ethernet Protocol Filter: 1. Select the interface or interfaces that will implement the filter from the Ethernet Protocol Filtering drop-down menu.
Filtering 2. Select the Filter Operation Type. — If set to Passthru, only the enabled Ethernet Protocols listed in the Filter Table will pass through the bridge. — If set to Block, the bridge will block enabled Ethernet Protocols listed in the Filter Table. 3. Configure the Ethernet Protocol Filter Table. This table is pre-populated with existing Ethernet Protocol Filters, however, you may enter additional filters by specifying the appropriate parameters.
Filtering Static MAC The Static MAC Address filter optimizes the performance of a wireless (and wired) network. When this feature is properly configured, the AP can block traffic between wired devices and wireless devices based on MAC address. For example, you can set up a Static MAC filter to prevent wireless clients from communicating with a specific server on the Ethernet network. You can also use this filter to block unnecessary multicast packets from being forwarded to the wireless network.
Filtering Taken together, a MAC Address/Mask pair specifies an address or a range of MAC addresses that the AP will look for when examining packets. The AP uses Boolean logic to perform an “AND” operation between the MAC Address and the Mask at the bit level. However, for most users, you do not need to think in terms of bits. It should be sufficient to create a filter using only the hexadecimal digits 0 and F in the Mask (where 0 is any value and F is the value specified in the MAC address).
Filtering When creating a filter, you can configure the Wired parameters only, the Wireless parameters only, or both sets of parameters. Which parameters to configure depends upon the traffic that you want block: To block all traffic ... Configure ... from a specific wired MAC address from being forwarded to the wireless network only the Wired MAC Address and Wired Mask (leave the Wireless MAC Address and Wireless Mask set to all zeros).
Filtering Figure 4-10.
Filtering Static MAC Filter Examples Consider a network that contains a wired server and three wireless clients.
Filtering Prevent Multiple Wireless Devices From Communicating With a Single Wired Device Configure the following settings to prevent Wireless Clients 1 and 2 from communicating with the Wired Server.
Filtering Prevent All Wireless Devices From Communicating With a Single Wired Device Configure the following settings to prevent all three Wireless Clients from communicating with Wired Server 1. • Wired MAC Address: 00:40:F4:1C:DB:6A • Wired Mask: FF:FF:FF:FF:FF:FF • Wireless MAC Address: 00:00:00:00:00:00 • Wireless Mask: 00:00:00:00:00:00 Result: The Access Point blocks all traffic between Wired Server 1 and all wireless clients.
Filtering Prevent Messages Destined for a Specific Multicast Group from Being Forwarded to the Wireless LAN If there are devices on your Ethernet network that use multicast packets to communicate and these packets are not required by your wireless clients, you can set up a Static MAC filter to preserve wireless bandwidth.
Filtering Advanced You can configure the following advanced filtering options: • Enable Proxy ARP: Place a check mark in the box provided to allow the Access Point to respond to Address Resolution Protocol (ARP) requests for wireless clients. When enabled, the AP answers ARP requests for wireless stations without actually forwarding them to the wireless network. If disabled, the Access Point will bridge ARP requests for wireless clients to the wireless LAN.
Filtering The AP can filter these protocols in the wireless-to-Ethernet direction, the Ethernet-to-wireless direction, or in both directions. Click Edit and use the Status field to Enable or Disable the filter. TCP/UDP Port Port-based filtering enables you to control wireless user access to network services by selectively blocking TCP/UDP protocols through the AP.
Filtering Adding TCP/UDP Port Filters 1. Place a check mark in the box labeled Enable TCP/UDP Port Filtering. 2. Click Add under the TCP/UDP Port Filter Table heading. 3. In the TCP/UDP Port Filter Table, enter the Protocol Names to filter. 4. Set the destination Port Number (a value between 0 and 65535) to filter. See the IANA Web site at http://www.iana.org/assignments/port-numbers for a list of assigned port numbers and their descriptions. 5.
Alarms Editing TCP/UDP Port Filters 1. Click Edit under the TCP/UDP Port Filter Table heading. 2. Make any changes to the Protocol Name or Port Number for a specific entry, if necessary. 3. In the row that defines the port, set the Status to Enable, Disable, or Delete, as appropriate. 4. Select OK. Alarms This category has three sub-categories.
Alarms Groups There are seven alarm groups that can be enabled or disabled via the Web interface. Place a check mark in the box provided to enable a specific group. Remove the check mark from the box to disable the alarms. Alarm Severity Levels vary. • Configuration Alarm Trap Name oriTrapDNSIPNotConfigured Description This traps is generated when the DNS IP Address has not been configured.
Alarms • Security Alarms Trap Name oriTrapAuthenticationFailure Description This trap is generated when a client authentication failure occurs. The authentication failures can range from: - MAC Access Control Table - RADIUS MAC Authentication - 802.1x Authentication specifying the EAP-Type Severity Level: Major oriTrapUnauthorizedManage rDetected This trap is generated when an unauthorized manager has attempted to view and/or modify parameters.
Alarms • Wireless Alarms Trap Name oriTrapWLCNotPresent Description When you start the AP, this trap is generated when a wireless interface/card is not present in the AP. Severity Level: Informational oriTrapWLCFailure This trap is generated when a general failure occurs with the wireless interface/card. Severity Level: Critical oriTrapWLCRemoval This trap is generated when the wireless interface/card has been removed from the device.
Alarms oriTrapWLCVoltageDiscrepa ncy The dual-radio AP supports 3.3 V and 5 V wireless cards. This trap is generated when a wireless interface/card using a different voltage is inserted in the AP. Severity Level: Critical oriTrapWLCIncompatibleVen dor This trap is generated when an incompatible wireless vendor card is inserted or present in the AP.
Alarms • Operational Alarms Trap Name oriTrapWatchDogTimerExpir ed Description This trap is generated when the software watch dog timer expires. This indicates that a problem has occurred with one or more software modules and the AP will reboot automatically. Trap Severity Level: Critical oriTrapRADIUSServerNotRe sponding This trap is generated when no response is received from the RADIUS server(s) for authentication requests sent from the RADIUS client in the AP.
Alarms oriTrapTaskSuspended This trap is generated when a software task in the AP is suspended. Trap Severity Level: Critical oriTrapBootPFailed In bootloader mode, this trap is generated when the AP does not receive a response from the BootP server. The result is that the Access Point reverts to its static IP configuration and you will need to set reset configuration options.
Alarms • FLASH Memory Alarms Trap Name oriTrapFlashMemoryEmpty Description This trap is generated when an error occurs while downloading a file to the AP and no data is present in the flash memory. Severity Level: Informational oriTrapFlashMemoryCorrupt ed This trap is generated when an error occurs while downloading a file to the AP and the data in the flash memory is invalid or corrupted.
Alarms oriTrapTFTPOperationComp leted This trap is generated when a TFTP operation is complete (upload or download). Severity Level: Informational • Image Alarms Trap Name oriTrapZeroSizeImage Description This trap is generated when a zero size image is loaded on the AP. Trap Severity Level: Major oriTrapInvalidImage This trap is generated when an invalid image is loaded in the Access Point.
Alarms In addition, the AP supports these standard traps, which are always enabled: • RFC 1215-Trap Trap Name coldStart Description The AP has been turned on or rebooted. Trap Severity Level: Informational linkUp The AP's Ethernet interface link is up (working). Trap Severity Level: Informational linkDown The AP's Ethernet interface link is down (not working).
Alarms topologyChan ge This trap is sent by the AP when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. This trap is not sent if a newRoot trap is sent for the same transition. Trap Severity Level: Informational All these alarm groups correspond to System Alarms that are displayed in the System Status screen, including the traps that are sent by the AP to the SNMP managers specified in the Alarm Host Table.
Alarms Informational alarms are there to provide the network administrator with some general information about the activities the AP is performing. Alarm Host Table To add an entry and enable the AP to send SNMP trap messages to a Trap Host, click Add, and then specify the IP Address and Password for the Trap Host. • IP Address: Enter the Trap Host IP Address. • Password: Enter the password in the Password field and the Confirm field.
Alarms Figure 4-11. Syslog Configuration Screen Setting Syslog Event Notifications Syslog Events are logged according to the level of detail specified by the administrator. Logging only urgent system messages will create a far smaller, more easily read log then a log of every event the system encounters.
Alarms Event LOG_EMERG LOG_ALERT Priority 0 1 LOG_CRIT LOG_ERR LOG_WARNING LOG_NOTICE 2 3 4 5 LOG_INFO LOG_DEBUG 6 7 Description system is unusable action must be taken immediately critical conditions error conditions warning conditions normal but significant condition informational debug-level messages Configuring Syslog Event Notifications You can configure the following Syslog settings from the HTTP interface: • Enable Syslog: Place a check mark in the box provided to enable system logging.
Bridge • Syslog Host Table: This table specifies the IP addresses of a network servers that the AP will send Syslog messages to. Click Add to create a new entry. Click Edit to change an existing entry. Each entry contains the following field: — IP Address: Enter the IP Address for the management host. — Comment: Enter an optional comment such as the host name. — Status: The entry is enabled automatically when saved (so the Status field is only visible when editing an entry).
Bridge The Bridge tab has four sub-categories. • Spanning Tree • Storm Threshold • Intra BSS • Packet Forwarding Spanning Tree A Spanning Tree is used to avoid redundant communication loops in networks with multiple bridging devices. Bridges do not have any inherent mechanism to avoid loops, because having redundant systems is a necessity in certain networks. However, redundant systems can cause Broadcast Storms, multiple frame copies, and MAC address table instability problems.
Bridge Storm Threshold Storm Threshold is an advanced Bridge setup option that you can use to protect the network against data overload by: • Specifying a maximum number of frames per second as received from a single network device (identified by its MAC address). • Specifying an absolute maximum number of messages per port.
Bridge Intra BSS The wireless clients (or subscribers) that associate with a certain AP form the Basic Service Set (BSS) of a network infrastructure. By default, wireless subscribers in the same BSS can communicate with each other. However, some administrators (such as wireless public spaces) may wish to block traffic between wireless subscribers that are associated with the same AP to prevent unauthorized communication and to conserve bandwidth.
Bridge Packet Forwarding The Packet Forwarding feature enables you to redirect traffic generated by wireless clients that are all associated to the same AP to a single MAC address. This filters wireless traffic without burdening the AP and provides additional security by limiting potential destinations or by routing the traffic directly to a firewall.
Security — A WDS connection (see Wireless Distribution System (WDS) for details) — Any (traffic is redirected to a port based on the bridge learning process) 4. Click OK to save your changes. Security The AP provides several security features to protect your network from unauthorized access.
Security Authentication and Encryption Modes The AP supports the following Security features: Type Description WEP Encryption The original encryption technique specified by the IEEE 802.11 standard. 802.1x Authentication An IEEE standard for client authentication. Wi-Fi Protected Access (WPA) A new standard that provides improved encryption security over WEP. WEP Encryption The IEEE 802.
Security • An 802.11b AP supports 64-bit and 128-bit encryption: — For 64-bit encryption, an encryption key is 10 hexadecimal characters (0-9 and A-F) or 5 ASCII characters (see ASCII Character Chart). — For 128-bit encryption, an encryption key is 26 hexadecimal characters or 13 ASCII characters. • An 802.11a or 802.
Security 802.1x Authentication IEEE 802.1x is a standard that provides a means to authenticate and authorize network devices attached to a LAN port. A port in the context of IEEE 802.1x is a point of attachment to the LAN, either a physical Ethernet connection or a wireless link to an Access Point. 802.1x requires a RADIUS server and uses the Extensible Authentication Protocol (EAP) as a standards-based authentication framework, and supports automatic key distribution for enhanced security.
Security Type Description EAP-Tunneled Transport Layer Security (TTLS) Certificate-based authentication (a certificate is required on the server; a client’s username/password is tunneled to the server over a secure connection); supports automatic key distribution PEAP - Protected EAP with MS-CHAP v2 Secure username/password-based authentication; supports automatic key distribution Different servers support different EAP types and each EAP type provides different features.
Security Authentication Process There are three main components in the authentication process. The standard refers to them as: 1. supplicant (client PC) 2. authenticator (Access Point) 3. authentication server (RADIUS server) When using Authentication Mode is set to 802.1x, WPA, or Mixed mode (802.1x and WEP), you need to configure your RADIUS server for authentication purposes.
Security Figure 4-12. RADIUS Authentication Illustrated The AP acts as a pass-through device to facilitate communications between the client PC and the RADIUS server. The AP (2) and the client (1) exchange 802.1x messages using an EAPOL (EAP Over LAN) protocol (A). Messages sent from the client station are encapsulated by the AP and transmitted to the RADIUS (3) server using EAP extensions (B).
Security For 802.11a and 802.11b/g clients that communicate with an AP, each client receives its own unique encryption key; this is known as Per User Per Session Encryption Keys. Wi-Fi Protected Access (WPA) Wi-Fi Protected Access (WPA) is a security standard designed by the Wi-Fi Alliance in conjunction with the Institute of Electrical and Electronics Engineers (IEEE). WPA is a sub-set of the forthcoming IEEE 802.11i security standard, currently in draft form. (IEEE 802.
Security WPA provides the following new security measures not available with WEP: • Improved packet encryption using the Temporal Key Integrity Protocol (TKIP) and the Michael Message Integrity Check (MIC).
Security NOTE: For more information on WPA, see the Wi-Fi Alliance Web site at http://www.wi-fi.org. The AP supports two WPA authentication modes: • WPA: The AP uses 802.1x to authenticate clients. You should only use an EAP that supports mutual authentication and session key generation, such as EAP-TLS, EAP-TTLS, and PEAP. See 802.1x Authentication for details. • WPA-PSK (Pre-Shared Key): For networks that do not have 802.
Security Configuring Security Settings You can configure each wireless interface to operate in one of the following Security modes: Security Mode Description No Security This is the default setting for an AP. Enable WEP Encryption The AP and clients use the same static WEP keys to encrypt data. Enable 802.1x Security The AP uses the 802.1x standard to communicate with a RADIUS server and authenticate clients.
Security Security Mode Description Enable WPA Mode The AP uses 802.1x to communicate with a RADIUS server and authenticate clients. The AP generates and distributes dynamic, per user encryption keys (based on the Temporal Key Integrity Protocol (TKIP)) to each client following successful authentication. WPA mode provides message integrity checking to guard against replay type attacks. This mode is not available for all radio types.
Security Authentication Mode Setting Authentication Method Employed Encryption Method Employed None None None or manually configured Static WEP settings (from Configure > Security > Encryption screen) 802.1x 802.1x Dynamic WEP Keying Mixed 802.1x or None (depends on a client's configuration) Dynamic WEP Keying or Static WEP (depends on client's configuration) WPA 802.
Security Enable WEP Encryption Follow these steps to set up WEP encryption on an AP: 1. Place a check mark in the box labeled Enable Encryption (WEP). 2. Enter one to four Encryption Keys in the fields provided. Keep in mind the following: — If entering more than one Key, use the same number of characters for each Key. All Keys need to be the same Key Size (64, 128, or 152-bit). — You can enter the Encryption Keys in either hexadecimal or ASCII format.
Security Enable 802.1x Security Follow these steps to enable 802.1x only: 1. Within the 802.1x Configuration screen, set 802.1x Security Mode to 802.1x. 2. Select an Encryption Key Length. — An 802.11b AP supports 64-bit and 128-bit encryption. — An 802.11a or 802.11b/g AP supports 64-bit and 128-bit encryption. 3. Enter a Re-keying Interval. — The Re-keying Interval determines how often a client’s encryption key is changed and can be set to any value between 60 - 65535 seconds.
Security Enable Mixed Mode (802.1x and WEP Encryption) Follow these steps to use both 802.1x and WEP Encryption simultaneously (clients that do not support 802.1x use WEP Encryption for security purposes): 1. Within the 802.1x Configuration screen, set 802.1x Security Mode to Mixed. 2. Enter a Re-keying Interval. — The Re-keying Interval determines how often a client’s encryption key is changed and can be set to any value between 60 - 65535 seconds.
Security — You can enter the Encryption Keys in either hexadecimal or ASCII format. — You need to manually configure your wireless clients that do not support 802.1x to use the same Encryption Key. 7. Confirm that Key 1 is selected in the Encrypt Data Transmissions Using drop-down menu. 8. Click OK. 9. If you have not already done so, configure the RADIUS authentication settings (see RADIUS Authentication with 802.1x for details). 10. Reboot the Access Point. 802.

WPA is NOT available for APs with an 802.11b PC Card or a 5 GHz Upgrade Kit. 1. Click Configure > Security > Authentication. 2. Set Authentication Mode to WPA-PSK. 3. Enter a Re-keying Interval. — The Re-keying Interval determines how often a client's encryption key is changed and can be set to any value between 60 and 65535 seconds.
Security 4. Configure the Pre-Shared Key. — You must also configure your clients to use this same key. — Do one of the following: • Enter 64 hexadecimal digits or 32 ASCII characters in the Pre-Shared Key field. See ASCII Character Chart for a hexadecimal to ASCII conversion chart. • Enter a phrase in the PSK Pass Phrase field. The AP will automatically generate a Pre-Shared Key based on the phrase you enter.
Security determines how the stations identified in the MAC Access Control Table are filtered. — If set to Passthru, only the addresses listed in the Control Table will pass through the bridge. — If set to Block, the bridge will block traffic to or from the addresses listed in the Control Table. • MAC Access Control Table: Click Add to create a new entry. Click Edit to change an existing entry. Each entry contains the following field: — MAC Address: Enter the wireless client’s MAC address.
Security Figure 4-13.
RADIUS RADIUS The AP communicates with a network’s RADIUS server to provide the following features: • MAC Access Control Via RADIUS Authentication • RADIUS Authentication with 802.
RADIUS The back-up servers are optional, but when configured, the AP will communicate with the back-up server if the primary server is off-line. After the AP has switched to the backup server, it will periodically check the status of the primary RADIUS server every five (5) minutes. Once the primary RADIUS server is again online, the AP automatically reverts from the backup RADIUS server back to the primary RADIUS server. All subsequent requests are then sent to the primary RADIUS server.
RADIUS 2. Place a check mark in the box labeled Enable Primary RADIUS Authentication Server. 3. If you want to configure a back-up RADIUS server, place a check mark in the box labeled Enable Back-up RADIUS Authentication Server. 4. Enter the time, in seconds, each client session may be active before being automatically re-authenticated in the Authorization Lifetime field. This parameter supports a value between 900 and 43200 sec; the default is 900 sec. 5. Select a MAC Address Format Type.
RADIUS 8. Enter the port number which the AP and the server will use to communicate. By default, RADIUS servers communicate on port 1812. 9. Enter the Shared Secret in the Shared Secret and Confirm Shared Secret field. This is a password shared by the RADIUS server and the AP. The same password must also be configured on the RADIUS server. 10. Enter the maximum time, in seconds, that the AP should wait for the RADIUS server to respond to a request in the Response Time field.
RADIUS Figure 4-14.
RADIUS RADIUS Authentication with 802.1x You must configure a primary RADIUS Authentication server to use 802.1x security. A back-up server is optional. NOTE: Problems with RADIUS Server configuration or RADIUS Authentication should be referred to the RADIUS Server developer. Follow these steps to enable a RADIUS Authentication server for 802.1x security: 1. Within the 802.1x Configuration screen, configure the 802.1x settings. See 802.1x Authentication for details. 2. Click the RADIUS tab. 3.
RADIUS — If you want to identify RADIUS servers by name, you must configure the AP as a DNS Client. See DNS Client for details. 8. Enter the server’s IP address or name in the field provided. 9. Enter the port number which the AP and the server will use to communicate. By default, RADIUS servers communicate on port 1812. 10. Enter the Shared Secret in the Shared Secret and Confirm Shared Secret field. This is a password shared by the RADIUS server and the AP.
RADIUS RADIUS Accounting Using an external RADIUS server, the AP can track and record the length of client sessions on the access point by sending RADIUS accounting messages per RFC2866. When a wireless client is successfully authenticated, RADIUS accounting is initiated by sending an “Accounting Start” request to the RADIUS server. When the wireless client session ends, an “Accounting Stop” request is sent to the RADIUS server.
RADIUS Configuring RADIUS Accounting Follow these steps to enable RADIUS accounting on the AP: 1. Within the RADIUS Accounting Configuration screen, place a check mark in the Enable RADIUS Accounting box to turn on this feature. 2. Place a check mark in the box labeled Enable Primary RADIUS Accounting Server. 3. If you want to configure a back-up RADIUS server, place a check mark in the box labeled Enable Back-up RADIUS Accounting Server. 4.
RADIUS 8. Enter the Shared Secret in the Shared Secret and Confirm Shared Secret field. This is a password shared by the RADIUS server and the AP. The same password must also be configured on the RADIUS server. 9. Enter the maximum time, in seconds, that the AP should wait for the RADIUS server to respond to a request in the Response Time field. Range is 1-10 seconds; default is 3 seconds. 10.
RADIUS Figure 4-15.
VLAN/SSID VLAN/SSID The AP allows you to segment wireless networks into multiple sub-networks based on Network Name (SSID) and VLAN membership. A Network Name (SSID) identifies a wireless network. Clients associate with Access Points that share its SSID. During installation, the Setup Wizard prompts you to configure one Network Name for each wireless interface.
VLAN/SSID VLANs now extend as far as the reach of the access point signal. Clients can be segmented into wireless sub-networks via SSID and VLAN assignment. A Client can access the network by connecting to an AP configured to support its assigned SSID/VLAN. AP devices are fully VLAN-ready; however, by default VLAN support is disabled.
VLAN/SSID VLAN tagged data is collected and distributed through an AP's wireless interface(s) based on Network Name (SSID). An Ethernet port on the access point connects a wireless cell or network to a wired backbone. The access points communicate across a VLAN-capable switch that analyzes VLAN-tagged packet headers and directs traffic to the appropriate ports. On the wired network, a RADIUS server authenticates traffic and a DHCP server manages IP addresses for the VLAN(s).
VLAN/SSID Figure 4-16.
VLAN/SSID VLAN Workgroups and Traffic Management Access Points that are not VLAN-capable typically transmit broadcast and multicast traffic to all wireless Network Interface Cards (NICs). This process wastes wireless bandwidth and degrades throughput performance. In comparison, VLAN-capable AP is designed to efficiently manage delivery of broadcast, multicast, and unicast traffic to wireless clients. The AP assigns clients to a VLAN based on a Network Name (SSID).
VLAN/SSID In this scenario, the AP would assign every packet it accepted to a VLAN. Each packet would then be identified as EMPLOYEE or GUEST, depending on which wireless NIC received it. The AP would insert VLAN headers or “tags” with identifiers into the packets transmitted on the wired backbone to a network switch. Finally, the switch would be configured to route packets from the EMPLOYEE workgroup to the appropriate corporate resources such as printers and servers.
VLAN/SSID NOTE: For Dual-radio APs: APs with an 11a Upgrade Kit or 802.11b/g Kit support up to 16 VLAN/SSID pairs. APs with an 802.11b PC Card or a 5 GHz Upgrade Kit support only one VLAN/SSID per radio. The four primary scenarios for using VLAN workgroups are as follows: VLAN disabled: Your network does not use VLANs, but you can configure the AP to use multiple SSIDs.
VLAN/SSID 4. Add one or more new SSID/VLAN entries. Follow these steps: NOTE: For Dual-radio APs: APs with an 11a Upgrade Kit or 802.11b/g Kit support up to 16 VLAN/SSID pairs. APs with an 802.11b PC Card or a 5 GHz Upgrade Kit support only one VLAN/SSID per radio. a. Click Add to create a new SSID/VLAN entry. b. Enter a Network Name (SSID), between 1 and 32 characters, in the field provided. c. Enter a VLAN ID in the field provided. — As defined by the 802.
VLAN/SSID — Click Edit if you want to modify an existing entry. You can also disable or delete an entry from the Edit screen. 5. Click the tab for the second wireless interface (if applicable) and create/modify SSID/VLAN entries as necessary. 6. Reboot the AP. Typical VLAN Management Configurations Control Access to the AP Management access to the AP can easily be secured by making management stations or hosts and the AP itself members of a common VLAN.
VLAN/SSID Provide Access to a Wireless Host in the Same Workgroup The VLAN feature can allow wireless clients to manage the AP. If the VLAN Management ID matches a VLAN User ID, then those wireless clients who are members of that VLAN will have AP management access. ! CAUTION: Once a VLAN Management ID is configured and is equivalent to one of the VLAN User IDs on the AP, all members of that User VLAN will have management access to the AP.

Troubleshooting 7 In This Chapter • Troubleshooting Concepts • Symptoms and Solutions • Recovery Procedures • Related Applications NOTE: This section helps you locate problems related to the AP device setup. For details about RADIUS, TFTP, serial communication programs (such as HyperTerminal), Telnet applications, or web browsers, please refer to the documentation that came with the application for assistance.
Troubleshooting Concepts Troubleshooting Concepts The following list identifies important troubleshooting concepts and topics. The most common initialization and installation problems relate to IP addressing. For example, you must have valid IP addresses for both the AP and the management computer to access the unit’s HTTP interface. • IP Address management is fundamental. • Factory default units are set for “Dynamic” (DHCP) IP Address assignment. The default IP address for the AP is 10.0.0.
Troubleshooting Concepts • The AP Supports a Command Line Interface (CLI). If you are having trouble locating your AP on the network, connect to the unit directly using the serial interface and refer to Command Line Interface (CLI) for CLI command syntax and parameter names.
Symptoms and Solutions Symptoms and Solutions Connectivity Issues Connectivity issues include any problem that prevents you from powering up or connecting to the AP. AP Unit Will Not Boot - No LED Activity 1. Make sure your power source is operating. 2. Make sure all cables are connected to the AP correctly. 3. If you are using Active Ethernet, make sure you are using a Category 5, foiled, twisted pair cable to power the AP. Serial Link Does Not Work 1.
Symptoms and Solutions 3. Make sure your PC terminal program (such as HyperTerminal) is active and configured to the following values: — Com Port: (COM1, COM2, etc. depending on your computer); — Baud rate: 9600; Data bits: 8; Stop bits: 1; Flow Control: None; Parity: None; — Line Feeds with Carriage Returns (In HyperTerminal select: File -> Properties -> Settings -> ASCII Setup -> Send Line Ends with Line Feeds) Ethernet Link Does Not Work 1. Double-check the physical network connections.
Symptoms and Solutions Basic Software Setup and Configuration Problems Lost AP, Telnet, or SNMP Password 1. Perform the Reset to Factory Default Procedure in this guide. This procedure resets system and network parameters, but does not affect the AP Image. The default AP HTTP password is “public”, and the default Telnet password is also “public”. Client Computer Cannot Connect 1. Client computers should have the same Network Name and security settings as the AP. 2.
Symptoms and Solutions AP Has Incorrect IP Address 1. Default IP Address Assignment mode is dynamic (DHCP). If you do not have a DHCP server on your network, the default IP Address is 10.0.0.1. If you have more than one unintialized AP connected to the network, they will all have the same default IP address and you will not be able to communicate with them (due to an IP address conflict).
Symptoms and Solutions 6. Perform the Reset to Factory Default Procedure in this guide. This will reset the unit to “DHCP” mode. If there is a DHCP Server on the network, the DHCP Server will assign an IP Address to the AP. HTTP (browser) or Telnet Interface Does Not Work 1. Make sure you are using a compatible browser: — Microsoft Internet Explorer 6 with Service Pack 1 or later — Netscape 6.1 or later 2. Make sure you have the proper IP address.
Symptoms and Solutions HTML Help Files Do Not Appear 1. Verify that the HTML Help files are installed in the default directory: C:\Program Files\Avaya_Wireless\AP\HTML\ 2. If the Help files are not located in this folder, contact your network administrator to find out where the Help files are located on your server. 3. Perform the following steps to verify the location or to enter the pathname for the Help files: a. Click the Commands button in the HTTP interface. b.
Symptoms and Solutions TFTP Server Does Not Work 1. Make sure the TFTP Server has been started. 2. Verify the IP address of the TFTP Server. The server may be local or remote, so long as it has a valid IP address. 3. Configure the TFTP Server to “point” to the folder containing the file to be downloaded (or to the folder in which the file is to be uploaded). 4. Verify that you have entered the proper AP Image file name (including the file extension) and directory path. 5.
Symptoms and Solutions Client Connection Problems Client Software Finds No Connection Make sure you have configured your client software with the proper Network Name and Security settings. Network Names and WEP Keys are typically allocated and maintained by your network administrator. Client PC Card Does Not Work 1. Make sure you are using the latest PC Card driver software. 2. Download and install the latest Avaya Wireless client software from http://www.avaya.com/support.
Symptoms and Solutions Intermittent Loss of Connection 1. Make sure you are within range of an active AP. 2. You can check the signal strength using the signal strength gauge on your client software. If you have an 802.11b AP, you can also use the Remote Link Test available in the Access Point’s HTTP interface. See Link Test (802.11b APs Only). Client Does Not Receive an IP Address - Cannot Connect to Internet 1.
Symptoms and Solutions VLAN Operation Issues Verifying Proper Operation of the VLAN Feature The correct VLAN configuration can be verified by “pinging” both wired and wireless hosts from both sides of the AP device and the network switch. Traffic can be “sniffed” on both the wired (Ethernet) and wireless (WDS) backbones (if configured). Bridge frames generated by wireless clients and viewed on one of the backbones should contain IEEE 802.1Q compliant VLAN headers or tags.
Symptoms and Solutions What if network traffic is being directed to a nonexistent host? • All sessions are disconnected, traffic is lost, and a manual override is necessary • Workaround: you can configure the switch to mimic the nonexistent host I have just configured the Management ID and now I can't manage the AP? • Check to ensure your password is correct. If your password is incorrect or all inbound packets do NOT have the correct tag, then a manual override is necessary.
Symptoms and Solutions 4. Try using a different Ethernet cable – if it works, there is probably a faulty connection over the long cable, or a bad RJ-45 connection. 5. Check power plug and hub. 6. If the Ethernet link goes down, check the cable, cable type, switch, and hub. There Is No Data Link 1. Verify that the indicator for the port is “on.” 2. Verify that the AE hub is connected to the Ethernet network with a good connection. 3.
Recovery Procedures “Overload” Indications 1. Verify that you are not using a cross-over cable between the AE output port and the AP. 2. Verify that there is no short over any of the twisted pair cables. 3. Move the device into a different output port – if it works, there is probably a faulty port or bad RJ-45 connection. Recovery Procedures The most common installation problems relate to IP addressing.
Recovery Procedures Reset to Factory Default Procedure Use this procedure to reset the network configuration values, including the Access Point’s IP address and subnet mask. The current AP Image is not deleted. Follow this procedure if you forget the Access Point’s password: 1. Press and hold the RELOAD button for 10 seconds. NOTE: See RELOAD and RESET Buttons to identify the buttons. You need to use a pin or the end of a paperclip to press a button.
Recovery Procedures Figure 7-1. RELOAD and RESET Buttons Forced Reload Procedure Use this procedure to erase the current AP Image and download a new AP Image. In some cases, specifically when a missing or corrupted AP Image prevents successful booting, you may need to use ScanTool or the Bootloader CLI to download a new executable AP Image.
Recovery Procedures NOTE: This does not delete the AP’s configuration (in other words, the Forced Reload Procedure does not reset to device to factory defaults). If you need to force the AP to the factory default state after loading a new AP image, use the Reset to Factory Default Procedure. For this procedure, you will first erase the AP Image currently installed on the unit and then use either ScanTool or the Bootloader CLI (over the serial port) to set the IP address and download a new AP Image.
Recovery Procedures 3. Follow one of the procedures below to load a new AP Image to the Access Point: — Download a New Image Using ScanTool — Download a New Image Using the Bootloader CLI Download a New Image Using ScanTool To download the AP Image, you will need an Ethernet connection to the computer on which the TFTP server resides and to a computer that is running ScanTool (this is either two separate computers connected to the same network or a single computer running both programs).
Recovery Procedures Download Procedure Follow these steps to use ScanTool to download a software image to an Access Point with a missing image: 1. Download the latest software from http://www.avaya.com/support. 2. Copy the latest software updates to your TFTP server. 3. Launch ScanTool. 4. Highlight the entry for the AP you want to update and click Change. 5. Set IP Address Type to Static.
Recovery Procedures 10. Enter the Image File Name (including the file extension). Enter the full directory path and file name. If the file is located in the default TFTP directory, you need enter only the file name. 11. Click OK. — Result: The Access Point will reboot and the download will begin automatically. You should see downloading activity begin after a few seconds within the TFTP server’s status screen. 12.
Recovery Procedures Preparing to Download the AP Image Before starting, you need to know the Access Point’s IP address, subnet mask, the TFTP Server IP Address, and the AP Image file name. Make sure the TFTP server is running and configured to point to the folder containing the image to be downloaded. Download Procedure 1. Download the latest software from http://www.avaya.com/support. 2. Copy the latest software updates to your TFTP server’s default directory. 3.
Recovery Procedures 4. Open your terminal emulation program (like HyperTerminal) and set the following connection properties: — Com Port: — Baud rate: 9600 — Data Bits: 8 — Stop bits: 1 — Flow Control: None — Parity: None 5. Under File -> Properties -> Settings -> ASCII Setup, enable the Send line ends with line feeds option. Result: HyperTerminal sends a line return at the end of each line of code. 6. Press the RESET button on the AP.
Recovery Procedures 7.
Recovery Procedures Setting IP Address using Serial Port Use the following procedure to set an IP address over the serial port using the CLI. The network administrator typically provides the AP IP address. Hardware and Software Requirements • Standard straight-through serial data (RS-232) cable with a one male DB-9 connector and one female DB-9 connector. The AP comes with a female 9-pin serial port. • ASCII Terminal software, such as HyperTerminal. Attaching the Serial Port Cable 1.
Recovery Procedures Initializing the IP Address using CLI After installing the serial port cable, you may use the CLI to communicate with the AP. CLI supports most generic terminal emulation programs, such as HyperTerminal (which is included with the Windows operating systems). In addition, many web sites offer shareware or commercial terminal programs you can download. Once the IP address has been assigned, you can use the HTTP interface or the CLI over Telnet to complete configuration.
Recovery Procedures Follow these steps to assign the AP an IP address: 1. Open your terminal emulation program (like HyperTerminal) and set the following connection properties: — Com Port: — Baud rate: 9600 — Data Bits: 8 — Stop bits: 1 — Flow Control: None — Parity: None 2. Under File -> Properties -> Settings -> ASCII Setup, enable the Send line ends with line feeds option. Result: HyperTerminal sends a line return at the end of each line of code. 3.
Recovery Procedures 5. Enter show ip. Result: Network parameters appear: Figure 7-2. Result of “show ip” CLI Command 6. Change the IP address and other network values using set and reboot CLI commands, similar to the example below (use your own IP address and subnet mask). Note that IP Address Type is set to Dynamic by default.
Related Applications 7. After the AP reboots, verify the new IP address by reconnecting to the CLI and enter a show ip command. Alternatively, you can ping the AP from a network computer to confirm that the new IP address has taken effect. 8. When the proper IP address is set, use the HTTP interface or CLI over Telnet to configure the rest of the unit’s operating parameters.
Related Applications TFTP Server The “Trivial File Transfer Protocol” (TFTP) server allows you to transfer files across a network. You can upload configuration files from the AP for backup or copying, and you can download configuration files or new software images. The TFTP software is located on the Avaya Wireless AP Installation CD-ROM. If a TFTP server is not configured and running, you will not be able to download and upload images and configuration files to/from the AP.
Command Line Interface (CLI) A In This Appendix This section describes the AP’s Command Line (CLI) Interface. CLI commands can be used to initialize, configure, and manage the Access Point. CLI commands may be entered in real time through a keyboard or submitted with CLI scripts. The CLI is available through both the Serial Port interface and over the Ethernet interface using Telnet. NOTE: All CLI commands and parameters are case-sensitive.
General Notes • Other Network Settings • CLI Monitoring Parameters • Parameter Tables General Notes Prerequisite Skills and Knowledge To use this document effectively, you should have a working knowledge of Local Area Networking (LAN) concepts, network access infrastructures, and client-server relationships. In addition, you should be familiar with software setup procedures for typical network operating systems and servers. Notation Conventions • Computer prompts are shown as constant width type.
General Notes Important Terminology Term Description Configuration Files Database files containing the current Access Point configuration. Configuration items include the IP Address and other network-specific values. Config files may be downloaded to the Access Point or uploaded for backup or troubleshooting. Download vs. Upload Downloads transfer files to the Access Point. Uploads transfer files from the Access Point. The TFTP server performs file transfers in both directions.
General Notes Term Description Parameter A fundamental network value that can be displayed and may be changeable. For example, the Access Point must have a unique IP Address and the Wireless interface must be assigned an SSID. Change parameters with the CLI set Command, and view them with the CLI show Command. Table Tables hold parameters for several related items. For example, you can add several potential managers to the SNMP Table.
General Notes Navigation and Special Keys This CLI supports the following navigation and special key functions to move the cursor along the prompt line.
General Notes CLI Error Messages The following table describes the error messages associated with improper inputs or expected CLI behavior. Error Message Syntax Error Invalid Command Invalid Parameter Name Invalid Parameter Value Invalid Table Index Invalid Table Parameter Invalid Table Parameter Value Read Only Parameter Incorrect Password Download Unsuccessful Upload Unsuccessful A-6 Description Invalid syntax entered at the command prompt. A non-existent command has been entered at the command prompt.
Command Line Interface (CLI) Variations Command Line Interface (CLI) Variations Administrators use the CLI to control Access Point operation and monitor network statistics. The AP supports two types of CLI: the Bootloader CLI and the normal CLI. The Bootloader CLI provides a limited command set, and is used when the current AP Image is bad or missing. The Bootloader CLI allows you to assign an IP Address and download a new image.
Command Line Interface (CLI) Variations The parameters supported by the Bootloader CLI (for viewing and modifying) are: • System Name • IP Address Assignment Type • IP Address • IP Mask • Gateway IP Address • TFTP Server IP Address • Image File Name (including the file extension) A-8 Avaya Wireless AP-3 User’s Guide
Command Line Interface (CLI) Variations The following lists display the results of using the help command in the Bootloader CLI: Figure A-1.
Command Line Interface (CLI) Variations The following lists display the results of using the show command in the Bootloader CLI: Figure A-2.
CLI Command Types CLI Command Types This guide divides CLI Commands into two categories: Operational and Parameter Controls. Operational CLI Commands These commands affect Access Point behavior, such as downloading, rebooting, and so on. After entering commands (and parameters, if any) press the Enter key to execute the Command Line.
CLI Command Types • search: Lists the parameters in a specified Table • upload: Uses TFTP server to upload “config” files from Access Point to TFTP default directory or specified path ? (List Commands) This command can be used in a number of ways to display available commands and parameters. The following table lists each operation and provides a basic example. Following the table are detailed examples and display results for each operation.
CLI Command Types Example 1. Display Command list To display the Command List, enter ?. [Device Name]>? Figure A-3. Result of “?” CLI command Example 2. Display specific Commands To show all commands that start with specified letters, enter one or more letters, then ? with no space between letters and ?. [Device Name]>s? Figure A-4.
CLI Command Types Example 3. Display parameters for set and show Example 3a allows you to see every possible parameter for the set (or show) commands. Notice from example 3a that the list is very long. Example 3b shows how to display a subset of the parameters based on initial parameter letters.
CLI Command Types Example 3a. Display every parameter that can be changed [Device Name]>set ? Figure A-5. Result of “set ?” CLI command . . . .
CLI Command Types Example 3b. Display parameters based on letter sequence This example shows entries for parameters that start with the letter “i”. The more letters you enter, the fewer the results returned. Notice that there is no space between the letters and the question mark. [Device Name]> show ipa? Figure A-6. Result of “show ipa?” CLI command [Device Name]> show iparp? Figure A-7.
CLI Command Types Example 4. Display Prompts for Successive Parameters Enter the command, a space, and then ?. Then, when the parameter prompt appears, enter the parameter value. Result: The parameter is changed and a new CLI line is echoed with the new value (in the first part of the following example, the value is the IP Address of the TFTP server).
CLI Command Types done, exit, quit Each of the following commands ends a CLI session: [Device Name]> done [Device Name]> exit [Device Name]> quit download Downloads the specified file from a TFTP server to the Access Point. Executing download in combination with the asterisks character (“*”) will make use of the previously set TFTP parameters. Executing download without parameters will display command help and usage information. 1.
CLI Command Types help Displays instructions on using control-key sequences for navigating a Command Line and displays command information and examples. 1. Using help as the only argument: [Device Name]>help Figure A-8.
CLI Command Types 2. Complete command description and command usage can be provided by: [Device Name]>help [Device Name]> help history Shows content of Command History Buffer. The Command History Buffer stores command statements entered in the current session. To avoid re-entering long command statements, use the keyboard “up arrow” (Ctrl-P) and “down arrow” (Ctrl-N) keys to recall previous statements from the Command History Buffer.
CLI Command Types reboot Reboots Access Point after specified number of seconds. Specify a value of 0 (zero) for immediate reboot. [Device Name]> reboot 0 [Device Name]> reboot 30 search Lists the parameters supported by the specified table. This list corresponds to the table information displayed in the HTTP interface. In this example, the CLI returns the list of parameters that make up an entry in the IP Access Table. [Device Name]> search mgmtipaccesstbl Figure A-9.
CLI Command Types upload Uploads a text-based configuration file from the AP to the TFTP Server. Executing upload with the asterisk character (“*”) will make use of the previously set/stored TFTP parameters. Executing upload without parameters will display command help and usage information. 1. Syntax to upload a file: [Device Name]>upload Example: [Device Name]>upload 192.168.1.100 APconfig.sys config 2.
CLI Command Types Parameter Control Commands The following sections cover the two Parameter Control Commands (show and set) and include several tables showing parameter properties. These commands allow you to view (show) all parameters and statistics and to change (set) parameters. • show: To see any Parameter or Statistic value, you can specify a single parameter, a Group, or a Table. • set: Use this CLI Command to change parameter values.
CLI Command Types Examples: [Device Name]>show ipaddr [Device Name]>show network [Device Name]>show mgmtipaccesstbl “set” CLI Command Sets (modifies) the value of the specified parameter. To see a definition and syntax example, type only set and then press the Enter key. To see a list of available parameters, enter a space, then a question mark (?) after set (example: set?). Syntax: [Device Name]>set [Device Name]>set ...CLI Command Types Configuring Objects that Require Reboot Certain objects supported by the Access Point require a device reboot in order for the changes to take effect. In order to inform the end-user of this behavior, the CLI provides informational messages when the user has configured an object that requires a reboot. The following messages are displayed as a result of the configuring such object or objects.
CLI Command Types Example 2: Executing the “exit”, “quit”, or “done” commands when an object that requires reboot has been configured In addition to the above informational message, the CLI also provides a message as a result of the exit, quit, or done command if changes have been made to objects that require reboot.
CLI Command Types “set” and “show” Command Examples In general, you will use the CLI show Command to view current parameter values and use the CLI set Command to change parameter values. As shown in the following examples, parameters may be set individually or all parameters for a given table can be set with a single statement. Example 1 - Set the Access Point IP Address Parameter Syntax: [Device Name]>set Example: [Device Name]> set ipaddr 10.0.0.
CLI Command Types Example 2 - Create a table entry or row Use 0 (zero) as the index to a table when creating an entry. When creating a table row, only the mandatory table elements are required (comment is usually an optional table element). For optional table elements, the default value is generally applied if you do not specify a value. Syntax: [Device Name]>set
… Example: [Device Name]> set mgmtipaccesstbl 0 ipaddr 10.0.0.CLI Command Types You can also modify several elements in the table entry. Enter the index number and specific table elements you would like to modify. (Hint: Use the search Command to see the elements that belong to the table.) [Device Name]>set mgmtipaccesstbl 1 ipaddr 10.0.0.12 ipmask 255.255.255.248 cmt “First Row” Example 4 - Enable, Disable, or Delete a table entry or row The following example illustrates how to manage the second entry in a table.
CLI Command Types Example 5 - Show the Group Parameters This example illustrates how to view all elements of a group or table. Syntax: [Device Name]> show Example: [Device Name]>show network Result: The CLI displays network group parameters. Note show network and show ip return the same data. Figure A-10.
CLI Command Types Example 6 - Show Individual and Table Parameters 1. View a single parameter. Syntax: [Device Name]>show Example: [Device Name]> show ipaddr Result: Displays the Access Point IP address. Figure A-11. Result of “show ipaddr” CLI Command 2. View all parameters in a table. Syntax: [Device Name]> show Example:[Device Name]> show mgmtipaccesstbl Result: Displays the IP Access Table and its entries.Using Tables & User Strings Using Tables & User Strings Working with Tables Each table element (or parameter) must be specified, as in the example below. [Device Name]>set mgmtipaccesstbl 0 ipaddr 10.0.0.10 ipmask 255.255.0.0 Below are the rules for creating, modifying, enabling/disabling, and deleting table entries. • Creation — The table name is required. — The table index is required – for table entry/instance creation the index is always zero (0).
Using Tables & User Strings • Modification — The table name is required. — The table index is required – to modify the table, “index” must be the index of the entry to be modified. — Only the table objects that are to be modified need to be specified. Not all the table objects are required. — If multiple table objects are to be modified the order in which they are entered is not important. — If the entire table entry is to be modified, all the table objects have to be specified.
Using Tables & User Strings Using Strings Since there are several string objects supported by the AP, a string delimiter is required for the strings to be interpreted correctly by the command line parser. For this CLI implementation, the single quote or double quote character can be used at the beginning and at the end of the string. For example: [Device Name]> set sysname Lobby - Does not need quote marks [Device Name]> set sysname “Front Lobby” - Requires quote marks.
Using Tables & User Strings ‘My “Desk” in the office’ Double Quotes within Single Quotes “Daniel’s Desk in the office” One Single Quote within Double Quotes ‘Daniel”s Desk in the office’ One Double Quote within Single Quotes The string delimiter does not have to be used for every string object. The single quote or double quote only has to be used for string objects that contain blank space characters.
Configuring the AP using CLI commands Configuring the AP using CLI commands Log into the AP using HyperTerminal 1. Open your terminal emulation program (like HyperTerminal) and set the following connection properties: — Com Port: — Baud rate: 9600 — Data Bits: 8 — Stop bits: 1 — Flow Control: None — Parity: None 2. Under File -> Properties -> Settings -> ASCII Setup, enable the Send line ends with line feeds option.
Configuring the AP using CLI commands Log into the AP using Telnet The CLI commands can be used to access, configure, and manage the AP using Telnet. Follow these steps: 1. Confirm that your computer’s IP address is in the same IP subnet as the AP. NOTE: If you have not previously configured the Access Point’s IP address and do not have a DHCP server on the network, the Access Point will default to an IP address of 10.0.0.1. 2. Go to the DOS command prompt on your computer. 3.
Set Basic Configuration Parameters Set Basic Configuration Parameters There are a few basic configuration parameters that you may want to setup right away when you receive the AP.
Set Basic Configuration Parameters Figure A-12. Result of “show system” CLI Command Set Static IP Address for the AP NOTE: The IP Subnet Mask of the AP must match your network’s Subnet Mask.
Set Basic Configuration Parameters Change Passwords [Device Name]>passwd (CLI password) [Device Name]>set httppasswd (HTTP interface password) [Device Name]>set snmprpasswd (SNMP read password) [Device Name]>set snmprwpasswd (SNMP read/write) [Device Name]>reboot 0 ! CAUTION: Avaya strongly urges you to change the default passwords to restrict access to your network devices to authorized personnel.
Set Basic Configuration Parameters Figure A-13.
Set Basic Configuration Parameters Set WEP Encryption for the Wireless Interface ! CAUTION: Wireless clients must be configured with the same encryption key to be able to communicate with the AP. The AP can only support one Key Length (so each of the configured keys must have the same length). The available key sizes vary based on the Access Point’s model. See Security Encryption Key Length Table for more information. You can set up to four encryption keys.
Set Basic Configuration Parameters Figure A-14. Result of “show wifsec” CLI Command Download an AP Configuration File from your TFTP Server Begin by starting your TFTP program. It must be running and configured to transmit and receive.
Set Basic Configuration Parameters After following the complete process (above) once, you can download a file of the same name (so long as all the other parameters are the same), with the following command: [Device Name]>download * Backup your AP Configuration File Begin by starting your TFTP program. It must be running and configured to transmit and receive. [Device Name]>upload
