PIX 525 Virtual MAC Address Configuration

Answered Question
Apr 3rd, 2007

I am currently setting up a pair of PIX 525 firewalls in an active/active arrangement with multiple security contexts. What is the difference between setting the MAC address and standby MAC address at the system level in the failover groups, or at an interface in a security context. I appear to be able to do any combination of one or the other or both? Which take s precidence? Is there a reason why you would use one or the other places to set the MAC and standby MAC?

I have this problem too.

Nope, you can still set them in the system config, under the 'failover group' section.

Either way works. However, I would suggest assigning the MACs in the failover group (that is what the command was designed for).

If you choose to set the MAC under the interface, then this will have precidence.

Thank you for the reply.

One follow up question. If the same interface is allocated in more than one security context, would it then be better to set different MAC addresses at the interface level for each security context?
