bridge port gvrpState For CoreBuilder 9000: Applies to Layer 3 switching modules only.
Allows the port to participate in sending and receiving GARP VLAN
Registration Protocol (GVRP) updates, which can help you simplify the
management of IEEE 802.1Q VLAN configurations.

Important Considerations
■
You can use this command to configure the same setting on multiple
ports simultaneously. When you specify multiple port numbers, the
system prompts you to choose the setting and then applies it to all of
the ports.
■
To activate GVRP in your system, you must enable it for the entire
bridge (see “bridge gvrpState”in Chapter 9) as well as on individual
bridge ports (this command). If you enable GVRP on a port but you
have not enabled it for the bridge, GVRP does not function.
■
To maximize the effectiveness of GVRP, it should be enabled in as
many end stations and network devices as possible.
■
GVRP updates are not sent to any blocked Spanning Tree Protocol
(STP) ports. GVRP operates only on ports that are in the forwarding
state.
■
If GVRP is enabled on the bridge and on a given port which changes
to the STP forwarding state, the port automatically begins to
participate in GVRP.
■
VLANs that are created dynamically with GVRP exist only as long as a
GVRP-enabled device is sending updates — if the devices no longer
send updates, GVRP is disabled, or the system is rebooted, all dynamic
VLANs are removed, but the system leaves unchanged all VLANs that
were statically configured through a management interface.
