MAC addresses of redundant interfaces on failover pair of CSS.

[dtochilovsky]

Helo all, I wanted to know what happens to the MAC addresses of the failover interfaces on the two CSS devices configured as a failover pair when a failover occurs?

Also what happens in a failover event in general? Can anyone point me to some documents describing the failover process.

Thank you,

Dmitry.

Usually a G-ARP is sent after a failover to update arp/cam tables.

Does anyone have any docs on the failover process of the CSS, what exaclty happens during failover in regards to the IP addresses of the circuits and the MAC addresses of the interfaces?

Thank you.

Dmitry.
