GVRP Configuration Guidelines
This section describes the guidelines for configuring GVRP:
• You can configure the per-port GVRP state only on the 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.
• When VTP pruning is enabled, it runs on all the GVRP-disabled 802.1Q trunk ports.
