reverse arp tools

[carl_townshend]

Hi all, is there any tools I can use to find an ip from a mac address ?

Carl,

on the router type:-

sh arp | inc <>

HTH.

[andrew.prince]

If you want to find the switch port the mac address is connect to:-

show mac-address-table | inc <>

for IOS switches

for CatOS, I think I remeber it's:-

show cam dynamic <>
