Rep Preempt Segment - Cisco Catalyst 3650 series Command Reference Manual

rep preempt segment

rep preempt segment
To manually start REP VLAN load balancing on a segment, use the rep preempt segment command in
privileged EXEC mode.
rep preempt segment segment-id
Syntax Description
segment-id
Command Default
Manual preemption is the default behavior.
Command Modes
Privileged EXEC (#)
Command History
Release
Cisco IOS XE Denali 16.2.2
Usage Guidelines
Enter this command on the segment, which has the primary edge port on the router.
Ensure that all the other segment configuration is completed before setting preemption for VLAN load
balancing. When you enter the rep preempt segment segment-id command, a confirmation message appears
before the command is executed because preemption for VLAN load balancing can disrupt the network.
If you do not enter the rep preempt delay seconds command in interface configuration mode on the primary
edge port to configure a preemption time delay, the default configuration is to manually trigger VLAN load
balancing on the segment. Use the show rep topology privileged EXEC command to see which port in the
segment is 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 command in interface configuration
mode on the REP primary edge port before you manually start preemption.
