Usage Guidelines

If the VLAN does not already exist, this command does not create the VLAN.

To avoid the delay introduced by relaying messages in software for link-failure or VLAN-blocking

notification during load balancing, REP floods packets at the hardware flood layer (HFL) to a regular

multicast address. These messages are flooded to the whole network, not just the REP segment. Switches

that do not belong to the segment treat them as data traffic. Configuring an administrative VLAN for the

whole domain can control flooding of these messages.

If no REP administrative VLAN is configured, the default is VLAN 1.

There can be only one administrative VLAN on a switch and on a segment.

The administrative VLAN cannot be the RSPAN VLAN.

This example shows how to configure VLAN 100 as the REP administrative VLAN:

Switch (config)# rep admin vlan 100

You can verify your settings by entering the show interface rep detail privileged EXEC command.
