How can I find the system/CPU MAC address of a Cisco ASR device? On a Catalyst switch, I can type
show mac address-table | include CPU
to find the system mac, but there's no mac address table on an ASR.
Thanks

That did not seem to work for me unfortunately, it does not recognize that command. It is an ASR9k if that helps at all.

Also,
show version
may totally show you the base Mac address on the switch for the device itself, as opposed to the interface Mac address totally!

I think there is no mac address for cpu in asr9k or any router.
The cpu mac in l2sw is use as source of some specific control frame like
stp dtp cdp lldp
In l3 device the mac address of interface is used control frame like
ospf bgp eigrp arp...etc.
Anyway I will make double check this point.

If that's the case, do you know the command to get the mac address of an interface?
