Check the ports assigned to VLANs on CISCO 6509 switch

[AndreyPokorskiy]

Hello,

I'm tring to find a port where the PC connected

I found from the core switch the IP address had been learned from VLAN505 (fro example)

#show ip route 10.x.x.x

Routing entry for 10.x.x.x/x
  Known via "connected", distance 0, metric 0 (connected, via interface)
  Routing Descriptor Blocks:
  * directly connected, via Vlan505
      Route metric is 0, traffic share count is 1

I'm tring to check what ports was assigned to this VALN (where this VALN physically connected)

What I did:

#show interfaces trunk | i 505

I got the list of port-chanels where this VLAN505 allowed on trunk

#show interfaces PoXX etherchannel

I found the interfaces connected to the PoXX

Next

#show cdp neighbors Gix/x/x

There I found where the MAC address

Do you know any other way how to check how VLAN connected to the switch?

Hi,

What about "sho vlan id ..." command?, that would show you the ports configured on a specifi vlan, example:

Switch#sh vlan id 20

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
20   VLAN0020                         active    Fa0/2, Fa0/8, Fa0/10, Fa0/13
                                                               Fa0/14
