Configure a specific MAC address on a L3 sub interface or on a VLAN interface

L1 Bithead

Good morning all,

 

is it possible to configure the mac address of an L3 sub interface in such a way that it is different from that of the physical interface?


Likewise, would it be possible to do the same with VLAN interfaces?

 

Thank you!

Hi!

 

You can't manually change the MAC addresses of the firewall interfaces

The only manipulation you can apply is by enabling HA in which case the firewall will assume it's HA MAC addresses of which the cluster ID is a variable part (so clusters in the same broadcast domains don't have ARP conflicts)
