Re: Physical ports in IOS

[John Kinsella <jlk () thrashyour com>]

"show mac-address-table" will give you a list of ethernet addresses and
what port they're on.  If you don't know your mac, "sh arp" might give
it to you, just ping your IP first, presuming you're on a local
subnet...

If you're unexperienced, be careful setting up span ports - do it wrong
on a production switch and there's a good chance you'll take down the
network. Might wanna go rent out a ccie lab online for a few hours to
putz around with, first.
