Configuring REP
Setting Manual Preemption for VLAN Load Balancing
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 to complete all other segment configuration 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.
Beginning in privileged EXEC mode, follow these steps on the switch that has the segment primary edge
port to manually trigger VLAN load balancing on a segment:
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. Beginning in privileged EXEC mode, follow these steps to
configure REP traps:
To remove the trap, enter the no snmp mib rep trap-rate global configuration command.
This example configures the switch to send REP traps at a rate of 10 per second:
Switch(config)# snmp mib rep trap-rate 10
Command Purpose
Step 1
rep preempt segment segment-id Manually trigger VLAN load balancing on the segment.
You need to confirm the command before it is executed.
Step 2
show rep topology View REP topology information.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
snmp mib rep trap-rate value Enable the switch to send REP traps, and set 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).
Step 3
end Return to privileged EXEC mode.
Step 4
show running-config Verify the REP trap configuration.
Step 5
copy running-config startup config (Optional) Save your entries in the switch startup configuration
file.
