Configuring GVRP on the Switch

The following sections describe how to configure GVRP.

Enabling GVRP Globally

You must enable GVRP globally before any GVRP will process on the switch. Enabling GVRP globally
enables GVRP to perform VLAN pruning on 802.1Q trunk links. Pruning occurs only on GVRP-enabled
trunks. For information on setting the per-trunk port GVRP enable state, see the
Individual 802.1Q Trunk Ports" section on page
To enable dynamic VLAN creation, you must explicitly enable dynamic VLAN creation globally on the
switch. For information on enabling dynamic VLAN creation, see the
Creation" section on page

shows the default GVRP configuration.
You can configure the per-port GVRP state only on 802.1Q-capable ports.
You must enable GVRP on both ends of an 802.1Q trunk link.
The GVRP registration mode for VLAN 1 is always fixed and is not configurable. VLAN 1 is always
carried by 802.1Q trunks on which GVRP is enabled.
When VTP pruning is enabled, it runs on all GVRP-disabled 802.1Q trunk ports.
