cGVRP 12.2(33)SRB The Compact (c) Generic Attribute Registration Protocol

(GARP) VLAN Registration Protocol (GVRP) feature

reduces CPU time for transmittal of 4094 VLAN states on a

port. GVRP enables automatic configuration of switches in

a VLAN network allowing network devices to dynamically

exchange VLAN configuration information with other

devices. GVRP is based on GARP which defines procedures

for registering and deregistering attributes with each other.

It eliminates unnecessary network traffic by preventing

attempts to transmit information to unregistered users.

GVRP is defined in IEEE 802.1Q.

The following commands were introduced or modified to

support this feature: clear gvrp statistics, debug gvrp,

gvrp global, gvrp mac-learning, gvrp registration, gvrp

timer, gvrp vlan create, show gvrp interface, show gvrp
