Displaying Tunnel Information

The command show tunnel displays the tunnels that the WSS switch is hosting to distribute to a locally attached VLAN. To display tunnel information, type the following command:

23x0# show tunnel
VLAN	Local Address	Remote Address	State	Port	LVID	RVID
--------------------------------------------------------------						---
vlan-eng	192.168.12.7	192.168.15.5	UP	1024	130	4103
vlan-eng	192.168.12.7	192.168.14.6	DORMANT	1026	130	4097
vlan-pm	192.168.12.7	192.168.15.5	UP	1024	4096	160

(For more information about this command and the fields in the output, see the Nortel Mobility System Software Command Reference.)

Understanding the Sessions of Roaming Users

When a wireless client successfully roams from one AP to another, its sessions are affected in the following ways:

•The WSS treats this client session as a roaming session and not a new session.

•RADIUS accounting is handled as a continuation of an existing session, rather than a new one.

•The session with the roamed-from AP is cleared from the WSS, even if the client does not explicitly disassociate from the AP and the IEEE 802.1X reauthentication period has not expired.

Roaming requires certain conditions and can be affected by some of the WSS’s timers. You can monitor a wireless client’s roaming sessions with the show sessions network verbose command.
