show vlans command

[fabio.marino]

Hi to all, till now to gather brief information about implemented vlan, especially the description, i use the "show vlan brief" command.

During my work i found devices that not support this command but only:

show vlans and the output is :

Virtual LAN ID:  13 (Inter Switch Link Encapsulation)

   vLAN Trunk Interface:   FastEthernet2/0.13

   Protocols Configured:      Address:              Received:        Transmitted:
           IP                       10.130.0.0         490963638           503785545

The devis is a router 7200 and ios 12.2(31).

Can someone explain this command and overall how can i get the description of the vlan?

Thanks

Hi,

sh vlan brief is for switches  and for switching modules on routers it is sh vlan-switch brief.

But here you have a subinterface with ISL encapsulation on a routed port of a router and so  if you want a descriptionof the vlan

I think you should try a sh cdp nei detail and hopefully if ther is a switch attached and provided you can telnet into itthen you should

have a description of that vlan.

Regards.

Ok, thanks.

I think i'll try to discover if a switch or mls is connect to the subinterface in order to get the vlan name. Great you give me a good solution thanks.
