To function as a Layer 3 device, the Wireless Edge Services xl Module requires
only one IP address, usually assigned to the default management interface.
(The default management interface is virtual LAN [VLAN] 1.) For some net-
work environments, however, you may want to assign IP addresses to other
VLAN. To do so, you must create VLAN interfaces.
Reasons to create a VLAN interface and assign it an IP address include:
■ You want the Wireless Edge Services xl Module to act as the Dynamic Host
Configuration Protocol (DHCP) server for stations in that VLAN.
■ You want the Wireless Edge Services xl Module to use Network Address
Translation (NAT) to translate IP addresses on another VLAN to an
address on this VLAN.
■ The Wireless Edge Services xl Module assigns stations in a Web authenti-
cation (Web-Auth) WLAN to this VLAN.
When you configure a WLAN to use Web-Auth, the module must have an
IP address on the static VLAN. (For more information about configuring
Web-Auth for a WLAN, see Chapter 5: Web Authentication for Mobile
Users.)
■ You want to enable routing between VLANs.
You can assign an IP address to a maximum of eight VLAN interfaces on the
Wireless Edge Services xl Module.
