rep admin vlan
Use the rep admin vlan global configuration command to configure a Resilient Ethernet Protocol (REP)
administrative VLAN for REP to transmit hardware flood layer (HFL) messages. Use the no form of this
command to return to the default configuration with VLAN 1 as the administrative VLAN.
rep admin vlan vlan-id
no rep admin vlan
Syntax Description
Defaults The administrative VLAN is VLAN 1.
Command Modes Global configuration
Command History
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.
Examples 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.
Related Commands
vlan-id The VLAN ID range is from 1 to 4094. The default is VLAN 1; the range to
configure is 2 to 4094.
Release Modification
