@phoebe changing the failover interface will break communication between the active and standby units. You should disable failover, then reconfigure the failover/state interface. Example:

interface gig0/3
 no shutdown
!
no failover
failover lan interface FAILOVER Gi0/3
failover interface ip FAILOVER 192.0.2.1 255.255.255.252 standby 192.0.2.2
failover link FAILOVER Gig0/3
failover

Once the failover changes have been made on both units, communication should be re-established. Use "show failover" to confirm communication has been re-established.

Hi Rob

thank you for the fast replay, and your help it worked. I was also trying to change the failover interface to a new interface on both active and secondary but the cisco doc didn't have a clear instruction. .
