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.
You can verify your settings by entering the show interfaces rep privileged EXEC command.
Examples
The following example shows how to configure a REP preemption time delay of 100 seconds on the primary
edge port.
Device(config)# interface TenGigabitEthernet 4/1
Device(config-if)# rep preempt delay 100
