Identifying port MAC on CatOS

[jdevoll]

What command allows you to see the MAC address used on a given switchport. Note that I am not asking for the MAC address of the device plugged into a switchport. Rather I am asking for the MAC address of the switchport itself.

Thank you in advance.

It might be like "show mod" , it gives you the range and you have to figure out which port it goes with starting at port 1 on a given module .

Hi Friend,

The easiest way is to issue a command

show port mac-address [mod[/port]

If you do not specify a module number, the MAC addresses for all ports on all modules are shown. If you specify a module number but no port number, the MAC addresses for all ports on the specified module are shown.

Have a look at this link for more details

But this command is supported in release 8.5 or later version.

But if you do not have this latest version or running older version of CATOS then the only option left is to run "sh mod" and from there you can get the serires of mac address for that particular module or line card.
