Hi
I've have six 3548xl switches, and have fibre links going from gigabit ports 1 and 2 to another. These links haven't been labeled, so I'm unsure which switch each fibre link is going to. Is there an IOS command (currently running IOS 12.0(5)) I could run that would show me the destination switch's mac address to which the connection is going into?
So to illustrate this, let's say I'm on switch 1 and the fibre link is running to another switch, what command could I run on switch 1 that will tell me the destination hardware address that the fibre is directly connected into?
Thanks in advance for your help.

Show mac-address table interface g1/0/1
this should show you the MAC addresses being learnt on the interface you type in.

Am I missing something here , why don't you just use CDP , this tells you exactly where it is going if it is a cisco switch on the far end . "show cdp neighbor detail" is your friend :-)
