Examples

When you enable preempt, the higher priority CSM preempts the other CSM in the fault-tolerant group when the higher priority CSM comes online. When you enable no preempt, the current primary CSM remains the primary CSM when the next CSM comes online.

You must set both members of the fault-tolerant CSM pair to preempt for this feature to work.

This example shows how to set the fault-tolerance mode to preempt:
