4.8.11 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.
