Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
rep admin vlan
rep admin vl an
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 v lan-id
no rep admin vlan
Syntax Description
Defaults The administrative VLAN is VLAN 1.
Command Modes Global configuration
Usage Guidelines If the VLAN does not already exist, this command does not create the VLAN.
To avoid the delay introduced by relaying mess ages in software for link-f ailure or VLAN-blocki ng
notification during load balanc ing, REP floods packets a t the hardware flood layer (H FL) to a regular
multicast address. These messages are flooded to the whole network, not just the REP segment. Switc hes
that do not belong to the segment treat them as data traffic. Configuring an administrative VLAN for the
whole domain can control floodin g of these messages.
If no REP administrative VLAN is configured, the default is VLAN 1.
There can be only one administrative VLA N 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 RE P administrative VLAN:
Switch(config)# rep admin vlan 100
You can verify your settings by entering the show interface rep detail privileged EXEC command.
