Rep Admin Vlan - Cisco Catalyst 4500 Series Configuration Manual

rep admin vlan

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.

Command History Release

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. You can control flooding of these messages
by configuring an administrative VLAN for the entire domain or segment-wise.
If no REP administrative VLAN is configured, the default is VLAN 1.
There can be any number of administrative VLANs as long as it is per segment.
The administrative VLAN cannot be the RSPAN VLAN.
Examples
The following example shows how to configure VLAN 100 as the REP administrative VLAN:
Switch(config)# rep admin vlan 100
