PAGE 53
Advanced Configuration • • Distance Between APs: 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. Multicast Rate: Sets the rate at which Multicast messages are sent.
PAGE 54
Advanced Configuration 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.
PAGE 55
Advanced Configuration 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.

PAGE 76
Advanced Configuration Security The AP provides several security features to protect your network from unauthorized access. • • • Authentication and Encryption Modes MAC Access Rogue Access Point Detection (RAD) Authentication and Encryption Modes The AP supports the following Security features: • • • WEP Encryption: The original encryption technique specified by the IEEE 802.11 standard. 802.1x Authentication: An IEEE standard for client authentication.
PAGE 77
Advanced Configuration NOTE The AP supports the following EAP types when Authentication Mode is set to 802.1x or WPA: EAP-TLS, PEAP, and EAP-TTLS. When Authentication Mode is set to Mixed, the AP supports the following EAP types: EAP-TLS, PEAP, EAP-TLLS, and EAP-MD5 (MD5 does not support automatic key distribution; therefore, if you choose this method you need to manually configure each client with the network's encryption key).
PAGE 78
Advanced Configuration 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).
PAGE 79
Advanced Configuration 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.
PAGE 80
Advanced Configuration 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. Click Configure > Security > Authentication. 2. Set Authentication Mode to Mixed. 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.
PAGE 81
Advanced Configuration 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. Rekeying frustrates hacking attempts without taxing system resources. Setting a fairly frequent rekey value (900 seconds=15 minutes) effectively protects against intrusion without disrupting network activities. 4.

Advanced Configuration Rogue Access Point Detection (RAD) The Rogue AP Detection (RAD) feature provides an additional security level for wireless LAN deployments. RAD detects unauthorized Access Points in the coverage area. When enabled, the Access Point scans the coverage area and identifies all active Access Points. Support is available for all versions and operation modes of Access Points. For example, an 802.11a Access Point identifies all similar Access Points.
PAGE 84
Advanced Configuration An example network deployment is shown. The Trusted AP has Rogue Access Detection enabled and the trap host is configured to be the management station. The Trusted AP on detecting the Rogue AP will send a trap to the management station with the Channel and BSSID of the Rogue Access Point. Configuring RAD Perform this procedure to enable RAD and define the Scan Interval and Scan Interface.
PAGE 85
Advanced Configuration RADIUS The AP communicates with a network’s RADIUS server to provide the following features: – – – MAC Access Control by way of RADIUS Authentication RADIUS Authentication with 802.1x RADIUS Accounting The network administrator can configure multiple RADIUS Authentication Servers for different Authentication types. The current available authentication types are EAP/802.1x authentication and MAC-based authentication.
PAGE 86
Advanced Configuration 6. Select a Server Addressing Format type (IP Address or Name). • If you want to identify RADIUS servers by name, you must configure the AP as a DNS Client. See DNS Client for details. 7. Enter the server’s IP address or name in the field provided. 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.

PAGE 88
Advanced Configuration 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.
PAGE 89
Advanced Configuration Figure 4-21 RADIUS Accounting Server Configuration 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.
PAGE 90
Advanced Configuration VLANs now extend as far as the reach of the access point signal. Clients can be segmented into wireless sub-networks by way of 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.
PAGE 91
Advanced Configuration 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).

Command Line Interface (CLI) 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.
PAGE 146
Command Line Interface (CLI) Example 3 - Modify a table entry or row Use the index to be modified and the table elements you would like to modify. For example, suppose the IP Access Table has one entry and you wanted to modify the IP address: [Device-Name]>set mgmtipaccesstbl 1 ipaddr 10.0.0.11 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.
