VLAN Configuration
7.7.11 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.
