GVRP—GARP VLAN Registration Protocol—is an application of the Generic Attribute Registration Protocol—GARP. GVRP is defined in the IEEE 802.1Q standard, and GARP is defined in the IEEE 802.1P standard.

To understand and use GVRP you must have a working knowledge of 802.1Q VLAN tagging. (See “Port-Based Virtual LANs (Static VLANs)” on page 9-50.)

GVRP uses “GVRP Bridge Protocol Data Units” (“GVRP BPDUs”) to “advertise ” static VLANs. In this manual, a GVRP BPDU is termed an advertisement.

GVRP enables the Switch 2512/2524 to dynamically create 802.1Q-compliant VLANs on links with other devices running GVRP. This enables the switch to automatically create VLAN links between GVRP-aware devices. (A GVRP link can include intermediate devices that are not GVRP-aware.) This operation reduces the chances for errors in VLAN configuration by automatically providing VLAN ID (VID) consistency across the network. That is, you can use GVRP to propagate VLANs to other GVRP-aware devices instead of manually having to set up VLANs across your network. After the switch creates a dynamic VLAN, you can optionally use the CLI static <vlan-id>command convert it to a static VLAN or allow it to continue as a dynamic VLAN for as long as needed. You can also use GVRP to dynamically enable port membership in static VLANs configured on a switch.
