Hello,

When I put in the below configuration, on our core ASA, it disrupts all communication to outside and dns inside.

I cleared the arp and xlate but the problem did not go away till I got rid of the commands completely.

Is there a way to put in these commands with out disrupting the core network or.. have just a short disruption?

      failover mac address GigabitEthernet0/0 001e.be7a.3333 001e.be7a.4444
      failover mac address GigabitEthernet0/1 001e.be7a.5555 001e.be7a.6666
      failover mac address GigabitEthernet0/2 001e.be7a.7777 001e.be7a.8888
      failover mac address Management0/0 001e.be7a.1111 001e.be7a.2222

Thanks in advance.

you probably need to clear the arp cache on the connected devices as well.

I cleared the arp and Mac table on the asa and 6513 core switches.

The 6513 even showed the new Mac. Everything seems to work but DNS translation. Their is a DNS server at the Colo and the HQ Datacenter.

The connected switches and devices had the arps cleared and servers reloaded. Still no joy.
