Usage Guidelines
When you enter the rep preempt segment segment-id command, a confirmation message appears before
the command is executed because preemption can cause network disruption.
Enter this command on the switch on the segment that has the primary edge port.
If you do not configure VLAN load balancing, entering this command results in the default
behavior—the primary edge port blocks all VLANs.
You configure VLAN load balancing by entering the rep block port {id port-id | neighbor_offset |
preferred} vlan {vlan-list | all} interface configuration command on the REP primary edge port before
you manually start preemption.
There is not a no version of this command.
Examples
This example shows how to manually trigger REP preemption on segment 100 with the confirmation
message:
Switch# rep preempt segment 100
The command will cause a momentary traffic disruption.
