C HAPT ER 1 Introducing the NWA This chapter introduces the main applications and features of the NWA. It also discusses the ways you can manage your NWA. 1.1 Introducing the NWA This User’s Guide covers the following models: NWA1121-NI, and NWA1123-NI. Your NWA is an IPv6 wireless AP (Access Point) that can function in several wireless modes. It extends the range of your existing wired network without additional wiring, providing easy network access to mobile users.
Chapter 1 Introducing the NWA 1.1.1 Dual-Band The NWA1123-NI is a dual-band AP and able to function both 2.4G and 5G networks at the same time. You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz band for time sensitive traffic like high-definition video, music, and gaming. Figure 1 Dual-Band Application 1.
Chapter 1 Introducing the NWA You can assign different wireless and security settings to each SSID profile. This allows you to compartmentalize groups of users, set varying access privileges, and prioritize network traffic to and from certain BSSs. To the wireless clients in the network, each SSID appears to be a different access point. As in any wireless network, clients can associate only with the SSIDs for which they have the correct security settings.
Chapter 1 Introducing the NWA In the figure below, the printer can receive requests from the wired computer clients A and B via the NWA in Client mode (Z) using only the 2.4 GHz band.
Chapter 1 Introducing the NWA 1.2.3 Root AP In Root AP mode, the NWA (Z) can act as the root AP in a wireless network and also allow repeaters (X and Y) to extend the range of its wireless network at the same time. In the figure below, both clients A, B and C can access the wired network through the root AP. Figure 4 Root AP Application On the NWA in Root AP mode, you can have multiple SSIDs active for reqular wireless connections and one SSID for the connection with a repeater (universal repeater SSID).
Chapter 1 Introducing the NWA clients and the wired LAN. Clients A and B access the AP and the wired network behind the AP throught repeaters Z and Y. Figure 5 Repeater Application When the NWA is in Repeater mode, universal repeater security between the NWA and other repeater is independent of the security between the wireless clients and the AP or repeater. If you do not enable universal repeater security, traffic between APs is not encrypted.
Chapter 1 Introducing the NWA 1.4 Configuring Your NWA’s Security Features Your NWA comes with a variety of security features. This section summarizes these features and provides links to sections in the User’s Guide to configure security settings on your NWA.

C HAPT ER 6 Wireless LAN 6.1 Overview This chapter discusses the steps to configure the Wireless Settings screen on the NWA. It also introduces the wireless LAN (WLAN) and some basic scenarios. Figure 19 Wireless Mode In the figure above, the NWA allows access to another bridge device (A) and a notebook computer (B) upon verifying their settings and credentials. It denies access to other devices (C and D) with configurations that do not match those specified in your NWA. 6.
Chapter 6 Wireless LAN • Use the MAC Filter screen to specify which wireless station is allowed or denied access to the NWA (see Section 6.9 on page 86). 6.3 What You Need To Know BSS A Basic Service Set (BSS) exists when all communications between wireless clients or between a wireless client and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless clients in the BSS.
Chapter 6 Wireless LAN Channel A channel is the radio frequency(ies) used by wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference. Wireless Mode The IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features.
Chapter 6 Wireless LAN The NWA secure communications via data encryption, wireless client authentication and MAC address filtering. It can also hide its identity in the network. User Authentication Authentication is the process of verifying whether a wireless device is allowed to use the wireless network. You can make every user log in to the wireless network before they can use it. However, every device in the wireless network has to support IEEE 802.1x to do this.
Chapter 6 Wireless LAN Passphrase A passphrase functions like a password. In WEP security mode, it is further converted by the NWA into a complicated string that is referred to as the “key”. This key is requested from all devices wishing to connect to a wireless network. PSK The Pre-Shared Key (PSK) is a password shared by a wireless access point and a client during a previous secure connection. The key can then be used to establish a connection between the two parties.
Chapter 6 Wireless LAN In the figure above, wireless clients A and B are trying to access the Internet via the NWA. The NWA in turn queries the RADIUS server if the identity of clients A and U are allowed access to the Internet. In this scenario, only client U’s identity is verified by the RADIUS server and allowed access to the Internet. The RADIUS server handles the following tasks: • Authentication which determines the identity of the users.

Table 25 WMM QoS Priorities Priority Level description voice Typically used for traffic that is especially sensitive to jitter. Use this priority to reduce latency for improved voice quality.
C HAPT ER 7 LAN 7.1 Overview This chapter describes how you can configure the IP address of your NWA. The Internet Protocol (IP) address identifies a device on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts. Figure 41 IPv4 Setup The figure above illustrates one possible setup of your NWA. The gateway IPv4 address is 192.168.1.
Chapter 7 LAN IPv6 IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP addresses. IPv6 Addressing The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000. IPv6 addresses can be abbreviated in two ways: • Leading zeros in a block can be omitted.

C HAPT ER 8 VLAN 8.1 Overview This chapter discusses how to configure the NWA’s VLAN settings. Figure 43 Management VLAN Setup B A In the figure above, to access and manage the NWA from computer A, the NWA and switch B’s ports to which computer A and the NWA are connected should be in the same VLAN. 8.1.1 What You Can Do in This Chapter The VLAN screens let you set up the NWA’s mangement VLAN (Section 8.3 on page 96). 8.
Chapter 8 VLAN VLAN also increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain. In traditional switched environments, all broadcast packets go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain. IEEE 802.1Q Tag The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN membership of a frame across bridges.
C HAPT ER 9 System 9.1 Overview This chapter shows you how to enable remote management of your NWA. It provides information on determining which services or protocols can access which of the NWA’s interfaces. Remote Management allows a user to administrate the device over the network.
Chapter 9 System • Use the SNMP screen to configure through which interface(s) and from which IP address(es) a network systems manager can access the NWA (see Section 9.7 on page 104). • Use the FTP screen to configure through which interface(s) and from which IP address(es) you can use File Transfer Protocol (FTP) to manage the NWA. You can use FTP to upload the latest firmware for example (see Section 9.8 on page 106). 9.
Chapter 9 System The next figure illustrates an SNMP management operation. Figure 47 SNMP Management Mode An SNMP managed network consists of two main types of component: agents and a manager. An agent is a management software module that resides in a managed device (the NWA). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions.

A PPENDIX C IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts. Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.
Appendix C IP Addresses and Subnetting The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID. Figure 88 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask.
Appendix C IP Addresses and Subnetting Subnet masks can be referred to by the size of the network number part (the bits with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes. Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks.
Appendix C IP Addresses and Subnetting The following table shows some possible subnet masks using both notations. Table 42 Alternative Subnet Mask Notation SUBNET MASK ALTERNATIVE NOTATION LAST OCTET (BINARY) LAST OCTET (DECIMAL) 255.255.255.0 /24 0000 0000 0 255.255.255.128 /25 1000 0000 128 255.255.255.192 /26 1100 0000 192 255.255.255.224 /27 1110 0000 224 255.255.255.240 /28 1111 0000 240 255.255.255.248 /29 1111 1000 248 255.255.255.
Appendix C IP Addresses and Subnetting The following figure shows the company network after subnetting. There are now two subnetworks, A and B. Figure 90 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address). 192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.

A PPENDIX D IPv6 Overview IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP addresses. IPv6 Addressing The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000. IPv6 addresses can be abbreviated in two ways: • Leading zeros in a block can be omitted.
Appendix D IPv6 Global Address A global address uniquely identifies a device on the Internet. It is similar to a “public IP address” in IPv4. A global unicast address starts with a 2 or 3. Unspecified Address An unspecified address (0:0:0:0:0:0:0:0 or ::) is used as the source address when a device does not have its own address. It is similar to “0.0.0.0” in IPv4. Loopback Address A loopback address (0:0:0:0:0:0:0:1 or ::1) allows a host to send packets to itself. It is similar to “127.0.0.1” in IPv4.
Appendix D IPv6 Table 52 Reserved Multicast Address (continued) MULTICAST ADDRESS FF0A:0:0:0:0:0:0:0 FF0B:0:0:0:0:0:0:0 FF0C:0:0:0:0:0:0:0 FF0D:0:0:0:0:0:0:0 FF0E:0:0:0:0:0:0:0 FF0F:0:0:0:0:0:0:0 Subnet Masking Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character (1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal characters.
Appendix D IPv6 combines its interface ID and global and subnet information advertised from the router. This is a routable global IP address. DHCPv6 The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a server-client protocol that allows a DHCP server to assign and pass IPv6 network addresses, prefixes and other configuration information to DHCP clients. DHCPv6 servers and clients exchange DHCP messages using UDP.
Appendix D IPv6 such as the system name. The interface-ID option provides slot number, port information and the VLAN ID to the DHCPv6 server. The remote-ID option (if any) is stripped from the Relay-Reply messages before the relay agent sends the packets to the clients. The DHCP server copies the interface-ID option from the Relay-Forward message into the Relay-Reply message and sends it to the relay agent. The interface-ID should not change even after the relay agent restarts.
Appendix D IPv6 determine whether the destination address is on-link and can be reached directly without passing through a router. If the address is onlink, the address is considered as the next hop. Otherwise, the NWA determines the next-hop from the default router list or routing table. Once the next hop IP address is known, the NWA looks into the neighbor cache to get the link-layer address and sends the packet when the neighbor is reachable.
Appendix D IPv6 Example - Enabling IPv6 on Windows XP/2003/Vista By default, Windows XP and Windows 2003 support IPv6. This example shows you how to use the ipv6 install command on Windows XP/2003 to enable IPv6. This also displays how to use the ipconfig command to see auto-generated IP addresses.

DHCPv6 is also enabled when you enable IPv6 on a Windows 7 computer. To enable IPv6 in Windows 7: 184 1 Select Control Panel > Network and Sharing Center > Local Area Connection. 2 Select the Internet Protocol Version 6 (TCP/IPv6) checkbox to enable it. 3 Click OK to save the change.

A PPENDIX E Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS).
Appendix E Wireless LANs disabled, wireless client A and B can still access the wired network but cannot communicate with each other. Figure 92 Basic Service Set ESS An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN.
Appendix E Wireless LANs An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless clients within the same ESS must have the same ESSID in order to communicate. Figure 93 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area.
Appendix E Wireless LANs cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Figure 94 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.
Appendix E Wireless LANs If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Preamble Type Preamble is used to signal that data is coming to the receiver. Short and long refer to the length of the synchronization field in a packet.
Appendix E Wireless LANs Table 55 Wireless LAN Standards Comparison Table WIRELESS LAN STANDARD MAXIMUM NET DATA RATE FREQUENCY BAND COMPATIBILITY IEEE 802.11a 54 Mbps 5 GHz IEEE 802.11n IEEE 802.11n 300 Mbps 2.4 GHz, 5 GHz IEEE 802.11b IEEE 802.11g IEEE 802.11a Wireless Security Overview Wireless security is vital to your network to protect wireless communication between wireless clients, access points and the wired network.
Appendix E Wireless LANs RADIUS RADIUS is based on a client-server model that supports authentication, authorization and accounting. The access point is the client and the server is the RADIUS server. The RADIUS server handles the following tasks: • Authentication Determines the identity of the users. • Authorization Determines the network services available to authenticated users once they are connected to the network. • Accounting Keeps track of the client’s network activity.
Appendix E Wireless LANs EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x.
Appendix E Wireless LANs LEAP LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. Dynamic WEP Key Exchange The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed.
Appendix E Wireless LANs Encryption WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA2 also uses TKIP when required for compatibility reasons, but offers stronger encryption than TKIP with Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP). TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server.
Appendix E Wireless LANs Wireless Client WPA Supplicants A wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA. At the time of writing, the most widely available supplicant is the WPA patch for Windows XP, Funk Software's Odyssey client. The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero Configuration" wireless client. However, you must run Windows XP to use it.
Appendix E Wireless LANs 1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters or 64 hexadecimal characters (including spaces and symbols). 2 The AP checks each wireless client's password and allows it to join the network only if the password matches. 3 The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID.

A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air.
Appendix E Wireless LANs • Directional antennas concentrate the RF signal in a beam, like a flashlight does with the light from its bulb. The angle of the beam determines the width of the coverage pattern. Angles typically range from 20 degrees (very directional) to 120 degrees (less directional). Directional antennas are ideal for hallways and outdoor point-to-point applications. Positioning Antennas In general, antennas should be mounted as high as practically possible and free of obstructions.
