4.5.11 GVRP
Generic Attribute Registration Protocol (GARP) VLAN Registration Protocol
(GVRP) is an application defined in the IEEE 802.1Q standard that allows for the
control of VLANs.
GVRP will run only on 802.1Q trunk ports and is used primarily to prune traffic
from VLANs that does not need to be passed between trunking switches. There
are some parameters to configure GVRP:
GVRP Enable: By default GVRP is not enabled for the switch. You must first
enable GVRP on the switch before you can configure the 802.1Q ports for
GVRP operation.
Port Mode: enables/disables GVRP on the individual 802.1Q trunk port.
GVRP must be configured on both sides of the trunk to work correctly.
Registration: By default GVRP ports are in normal registration mode. These
ports use GVRP join messages from neighboring switches to prune the
VLANs running across the 802.1Q trunk link. If the device on the other side
is not capable of sending GVRP messages, or if you do not want to allow the
switch to prune any of the VLANs, use the fixed mode. Fixed mode ports will
forward for all VLANs that exist in the switch database. Ports in forbidden
mode forward only for VLAN 1.
