3com WXR100 3CRWXR10095A User Manual

Tunnels connect WX switches. Tunnels are formed automatically in a 
Mobility Domain to extend a VLAN to the WX switch 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. 

MSS 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 WX switches, the tunnels can carry user traffic of any protocol 
type.

MSS provides the following commands to display the roaming and 
tunneling of users within their Mobility Domain groups:

„

display roaming station (See “Displaying Roaming Stations” on 
page 159.)

„

display roaming vlan (See “Displaying Roaming VLANs and Their 
Affinities” on page 160.)

„

display tunnel (See “Displaying Tunnel Information” on page 160.)

The command display roaming station displays a list of the stations 
roaming to the WX switch through a VLAN tunnel. To display roaming 
stations (clients), type the following command:

WX1200# display roaming station
User Name              Station Address   VLAN            State
