Determine which port servers/clients are plugged into

[8pcallahan]

On a new Catalyst 6509 running IOS is there a way to tell which port a particular server or client is plugged into? (Without tracing patch cables)

I have done this on old switch gear with ARP and/or CAM tables. Does not appear to be the same on this new switch.

Thanks.

Hi

if you know the mac-address already

1) sh mac-address-table address "mac address"

If you need the IP address of the server first

1) sh arp | include "IP address".

from this you get the mac-address

2) as above.
