Fail Back Manually
If you have configured a CAM spare-group for manual failback, user traffic is handled by the spare CAM until it is manually
forced back to the original CAM by doing a shutdown / no shutdown on the spare-group leader.
1. (If necessary) Display the CAM spare-groups:
show spare-group
Example output:
Slot Leader Slot Mode
0 0 manual
1 0
2. Verify the status of the spare-group leader and original CAM:
show linecard status
The original CAM must be in-service (IS) and Protected. The spare-group leader after a failover is marked IS and Active.
