Monitoring the VLANs and tunnels in a Mobility Domain
Tunnels connect WSSs. Tunnels are formed automatically in a Mobility Domain to extend a VLAN to the WSS that a
roaming station is associated with. A single tunnel can carry traffic for many users and many VLANs. The tunnel port
can carry traffic for multiple VLANs by means of multiple virtual ports.
WSS Software automatically adds virtual ports to VLANs as needed to preserve the associations of users to the correct
subnet or broadcast domain as they roam across the Mobility Domain. Although tunnels are formed by IP between WSS
switches, the tunnels can carry user traffic of any protocol type.
WSS Software provides the following commands to display the roaming and tunneling of users within their Mobility
Domain groups:
• show roaming station (See “Displaying roaming stations” on page 226.)
• show roaming vlan (See “Displaying roaming VLANs and their affinities” on page 227.)
• show tunnel (See “Displaying tunnel information” on page 227.)
Displaying roaming stations
The command show roaming station displays a list of the stations roaming to the WSS through a VLAN tunnel. To
display roaming stations (clients), type the following command:
WSS# show roaming station
(For more information about this command and the fields in the output, see the Nortel WLAN Security Switch 2300
Series Command Line Reference.)
