Method used to view the MAC address of a device on USG firewalls

The method used to view the MAC address of a device on the USG2000, USG5000, and USG6000 is as follows:
You cannot view the MAC address of a device on the web UI on USG firewalls.
You can run the display arp command in the command line to view the local MAC address and peer MAC address.
