Existng setup:


SW-Dist1 SW-Dist2

| |

SW1 SW2

ACE 1 --- ACE2

Active

C1

C2

C3


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.

With ACE you have 3 tracking options

you can track host (an ip), track an Interface and an HSRP group.


Tracking interface option is applicable for VLAN interfaces only. It cannot track port channel/ physical interface.


In your case the best option would be to track HSRP group configured on the uplink devices.

Thanks Iftekhar for the link, Is tracking HSRP group good for ACE if it is deployed in Bridge mode ?

Sure.

Infact HSRP tracking is the recommended option for bridge mode.
