Monitoring and Maintaining REP
Setting Manual Preemption for VLAN Load Balancing
Before You Begin
If you do not enter the rep preempt delay seconds interface configuration command on the primary edge port to
configure a preemption time delay, the default is to manually trigger VLAN load balancing on the segment. Be sure that
all other segment configuration has been completed before manually preempting VLAN load balancing. 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.
Configuring SNMP Traps for REP
You can configure the switch to send REP-specific traps to notify the SNMP server of link operational status changes and
port role changes.

Configuration Examples for Configuring REP
Configuring the Administrative VLAN: Example
This example shows how to configure the administrative VLAN as VLAN 100 and verify the configuration by entering the
show interface rep detail command on one of the REP interfaces:
Switch# configure terminal
Switch (conf)# rep admin vlan 100
Switch (conf-if)# end
Switch# show interface GigabitEthernet1/17 rep detail
Command Purpose
1. rep preempt segment segment-id Manually triggers VLAN load balancing on the segment.
You will need to confirm the command before it is executed.
2. show rep topology Displays REP topology information.
Command Purpose
1. configure terminal Enters global configuration mode.
2. snmp mib rep trap-rate value Enables the switch to send REP traps, and sets the number of
traps sent per second. The range is from 0 to 1000. The default
is 0 (no limit imposed; a trap is sent at every occurrence).
3. end Returns to privileged EXEC mode.
Command Purpose
show interface [interface-id] rep [detail] Displays REP configuration and status for an interface or for all
interfaces.
show rep topology [segment segment_id] [archive]
[detail]
Displays REP topology information for a segment or for all
segments, including the primary and secondary edge ports in
the segment.
copy running-config startup config Saves your entries in the switch startup configuration file.
