Issue Description
Do All Interfaces Have MAC Addresses?
Solution
Each Layer 3 Ethernet interface has a MAC address.

A VLANIF interface obtains the device MAC address as its own MAC address. This MAC address is fixed.

A Bridge-if interface obtains the device MAC address as its own MAC address. This MAC address can be changed using the CLI.

The MAC address of a Layer 2 interface has no function on the AR.

NOTE:
  • To change the device MAC address, run the set system-mac { current | default } command in the diagnosis view, save the configuration, and restart the device.
  • The system MAC address to be modified cannot be a multicast MAC address.
