For CatOS switches, "show cam dynamic (slot/port)"

For IOS switches, "show mac-address (slot/port)"

I dont think this is a valid command (show mac-address). I know you can use show mac-address-table to view ports mac addresses. What I am looking for, is a command to view a mac address for a device that is connected to a particular switch port (Forinstance, mac address for a pc connected to fa3/10)

I'm sorry, you are right. The IOS command is "show mac address-table interface (interface ID)". Good luck.

the information you need is included in the output of "show mac-address-table"

Thanks Mark and Yuangi. Actually the show ma-address-table int (mod/port) will display the mac address of the device connected to that particular port. Again, thanks for your inputs.
