Configuring REP
Enter the no form of each command to return to the default configuration. Enter the show rep topology
privileged EXEC command to see which port in the segment is the primary edge port.

Step 7
rep block port {id port-id | neighbor_offset |
preferred} vlan {vlan-list | all}
preferred} vlan {vlan-list | all}
(Optional) Configure VLAN load balancing on the primary edge
port, identify the REP alternate port, and configure the VLANs to be
blocked on the alternate port.
port, identify the REP alternate port, and configure the VLANs to be
blocked on the alternate port.
•
Enter the id port-id to identify the alternate port by port ID. The
port ID is automatically generated for each port in the segment.
You can view interface port IDs by entering the show interface
interface-id rep [detail] privileged EXEC command.

You can view interface port IDs by entering the show interface

•
Enter a neighbor_offset number to identify the alternate port as
a downstream neighbor from an edge port. The range is from
–256 to 256, with negative numbers identifying the downstream
neighbor from the secondary edge port. A value of 0 is invalid.
Enter -1 to identify the secondary edge port as the alternate port.

a downstream neighbor from an edge port. The range is from
–256 to 256, with negative numbers identifying the downstream
neighbor from the secondary edge port. A value of 0 is invalid.
Enter -1 to identify the secondary edge port as the alternate port.
See
for an example of neighbor offset
numbering.
Note
Because you enter this command at the primary edge port
(offset number 1), you would never enter an offset value of 1
to identify an alternate port.

to identify an alternate port.
•
Enter preferred to select the regular segment port previously
identified as the preferred alternate port for VLAN load
balancing.
identified as the preferred alternate port for VLAN load
balancing.
•
Enter vlan vlan-list to block one VLAN or a range of VLANs.
•
Enter vlan all to block all VLANs.
Note
Enter this command only on the REP primary edge port.
Step 8
rep preempt delay seconds
(Optional) 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. The time delay range is 15 to 300
seconds. The default is manual preemption with no time delay.

Note
Enter this command only on the REP primary edge port.
Step 9
rep lsl-age-timer value
(Optional) Configure a time (in milliseconds) for which the REP
interface remains up without receiving a hello from a neighbor. The
range is from 3000 to 10000 ms in 500 ms increments; the default is
5000 ms (5 seconds).

Step 10
end
Return to privileged EXEC mode.
Step 11
show interface [interface-id] rep [detail]
Verify the REP interface configuration.
Step 12
copy running-config startup config
(Optional) Save your entries in the switch startup configuration file.
