Locating MAC addresses on a 6509 switch

On my 35xx switches, I am able to locate what interface a MAC address is connected to by using the the "sho mac" command.

Is there a comparable command for the 6509?

Note, my 6509 has a MSFC2 card for routing and Gigabit interfaces 6416-GBIC connecting to the 35xx switches. I can get the arp table with sho ip arp, but it lists the mac address and ip address as going to a VLAN, but the VLAN is on almost every interface. If I knew the gigabit port I could tell which 35xx switch and then find the actual ethernet port.

Assuming your running CatOS on your 6509. If so then the "show cam" command will show you the mac to port table that the "show mac" command does on your 35xx switches. If you are running Natvie IOS on your 6509 "show mac" is the command you need.

Run the "show cam dynamic" command on the supervisor.

do a sh cam xx-xx-xx-xx-xx

the mac must be entered with dashes
