About show vlan brief command.

[speculor_cisco]

I had a very simple question.

I wondered if, in the output of the show vlan brief command, I can see also the ports belonging to an active VLAN but in a state different from up/up.

For example, if I shutdown an interface, can I see the interface under the field Ports of the output?

Thanks.

Hi,

Yes, you can see those ports in the output as below,

SWITCH#show vlan brief

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
1    default                          active    Gi1/4, Gi1/5
1002 fddi-default                     act/unsup
1003 token-ring-default               act/unsup
1004 fddinet-default                  act/unsup
1005 trnet-default                    act/unsup
SWITCH#show int g1/4 | inc pro
GigabitEthernet1/4 is administratively down, line protocol is down (disabled)
     0 unknown protocol drops
SWITCH#

Hello Nagendra and thanks for your answer.

I suppose this is the same also for status not up/up but different from administratively down.

Is it true?

Hi,

Yes. Even if it is UP/DOWN or DOWN/DOWN, still it will be shown in the output.

Hi,

Even you admin down a port and not removed the vlan from interface configuration, the interface will still show in VLAN ports.

Once you removed the vlan from the interface configuration then that port will show in the default vlan.

Hope this clear you...
