3Com WX2200 3CRWX220095A, WXR100 3CRWXR10095A Monitoring, VLANs and Tunnels, A Mobility, Domain

Monitoring the VLANs and Tunnels in a Mobility Domain 159

Monitoring the	Tunnels connect WX switches. Tunnels are formed automatically in a
VLANs and Tunnels	Mobility Domain to extend a VLAN to the WX switch that a roaming
in a Mobility	station is associated with. A single tunnel can carry traffic for many users
Domain	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.)

Displaying Roaming The command display roaming station displays a list of the stations Stations roaming to the WX switch through a VLAN tunnel. To display roaming

stations (clients), type the following command:

WX1200# display roaming station		VLAN	State
User Name	Station Address
