Redundancy in physical interface tracking .

[gopi_sivam]

Hi ,

We are managing almost 20 ACE in different location in HA mode . Right now the configuration is for redundancy in  ft group and ft track in user context and this redundancy are working well good . My new requirement is to track the physical interface in admin context ,where my  ACE designed  to track only the  interface vlan now in user context  .

                                When two interface goes down in the ace , failover should happen to secondary . where all the four interface is bundle in single port channel . when two interface goes down , load in the port channel  will be increased  to avoid this , any redundant configuration is there ?  to switchover the active role to secondary .

Hi,

If a port in a channel goes down, it is treated as a link failure and its traffic is transferred to one or more of the remaining ports in the channel by design.

But one option is to track a neighbor router IP with the host tracking option (not used with port channel though) .
