GARP VLAN Registration (GVRP)

Overview

GARP VLAN Registration (GVRP) is supported on platforms c, e, and s

Commands

The GVRP commands are:

• bpdu-destination-mac-address

• clear gvrp statistics

• debug gvrp

• disable

• garp timers

• gvrp enable

• gvrp registration

• protocol gvrp

• show config

• show garp timers

• show gvrp

• show gvrp statistics on page 27

The GARP (Generic Attribute Registration Protocol) mechanism allows the configuration of a GARP

participant to propagate through a network quickly. A GARP participant registers or de-registers its

attributes with other participants by making or withdrawing declarations of attributes. At the same

time, based on received declarations or withdrawals, GARP handles attributes of other participants.

GVRP enables a device to propagate local VLAN registration information to other participant devices

and dynamically update the VLAN registration information from other devices. The registration

information updates local databases regarding active VLAN members and through which port the

VLANs can be reached.

GVRP ensures that all participants on a bridged LAN maintain the same VLAN registration

information. The VLAN registration information propagated by GVRP include both manually

configured local static entries and dynamic entries from other devices.

GVRP participants have the following components:

• The GVRP application

• GARP Information Propagation (GIP)

• GARP Information Declaration (GID)
