ASA check mac address on physical interface

Hi all,

Is there a command to check mac addresses on CLI on physical interfaces "switchport" because when you use : show arp you see mac addresses associated to the interface alias ?

thx

"show interface" will show you the mac address of the interface.

Ping the physical interface ip address from the ASA, and whatever the arp association of the ip address should show up under "show arp".

There is no other way to check the physical mac address of other device from the ASA.
