sh mac address on native mode Cat 6000 switches

Before the native mode upgrade on our cat 6000 switch we could run a

command to find what port a device was plugged in. SHOW MAC ADDRESS

H.H.H. But now ths command doesn't show you the info you need.

Does anyone know of what commands you can run to find the ports specific

devices are plugged into. Using either IP or MAC ?

All you get now is something like:

vlan mac address type protocol qos ports

------+----------------+--------+---------+---+-------------------

191 0080.5fa6.dd4f dynamic ip -- Po1

Re: sh mac address on native mode Cat 6000 switches

Looks like in your case the MAC address is being learnt of Port Channel 1. The command you are using is correct and here is an example from my lab switch

Router#sh mac-address-table dynamic

vlan mac address type protocol qos ports

-----+---------------+--------+---------+---+--------------------------------

1 0030.7b4e.6400 dynamic assigned -- Gi2/1

4095 0000.0000.0000 dynamic ip -- Router

10 0030.7b4e.6400 dynamic assigned -- Gi2/1

1 0030.7b4e.6400 dynamic other -- Gi2/1

Router#sh mac-address-table address 0030.7b4e.6400

vlan mac address type protocol qos ports

-----+---------------+--------+---------+---+--------------------------------

1 0030.7b4e.6400 dynamic assigned -- Gi2/1

10 0030.7b4e.6400 dynamic assigned -- Gi2/1

1 0030.7b4e.6400 dynamic other -- Gi2/1

Re: sh mac address on native mode Cat 6000 switches

thanks for the feed back. What is Po1 ? I've been chasing a mac address

trying to find its location. When the sh mac shows Po1 and I run sh cdp ne.

How do I know what port its learning it from so I can look on the next device?

thanks
