User Guidelines
When nonstop forwarding is enabled on a stack, the stack's management unit
checkpoints operational data to the backup unit. If the backup unit takes over
as the management unit, the control plane on the new management unit uses
the checkpoint data when initializing its state. Checkpoint statistics track the
amount of data checkpointed from the management unit to the backup unit.
Example
console#clear checkpoint statistics
clear counters stack-ports
Use the clear counters stack-ports command to clear the statistics for all
stack-ports.
