rep preempt delay

Use the rep preempt delay interface configuration command on the REP primary edge port to configure

a waiting period after a segment port failure and recovery before Resilient Ethernet Protocol (REP)

VLAN load balancing is triggered. Use the no form of this command to remove the configured delay.

Syntax Description

No preemption delay is set. If you do not enter the rep preempt delay command, the default is manual

preemption with no delay.

Usage Guidelines

You must enter this command on the REP primary edge port.

You must enter this command and configure a preempt time delay if you want VLAN load balancing to

automatically trigger after a link failure and recovery.

If VLAN load balancing is configured, after a segment port failure and recovery, the REP primary edge

port starts a delay timer before VLAN load balancing occurs. Note that the timer restarts after each link

failure. When the timer expires, the REP primary edge alerts the alternate port to perform VLAN load

balancing (configured by using the rep block port interface configuration command) and prepares the

segment for the new topology. The configured VLAN list is blocked at the alternate port, and all other

VLANs are blocked at the primary edge port.

This example shows how to configure a REP preemption time delay of 100 seconds on the primary edge

Switch (config)# interface gigabitethernet0/1

Switch (config-if)# rep preempt delay 100

Switch (config-if)# exit

You can verify your settings by entering the show interfaces rep privileged EXEC command.
