ACE 1 --- ACE2
where C1-3 are contexts, all contexts are active in ACE1.
These ACE are modules in 6504 switches.
SW1 and SW2 respectively.
SW1 and SW2 are trunked to Distribution Switches via port channels.
Requirement is to implement failover by tracking uplink port-channel availability.
How to achieve this? Any help is much appreciated.
