bridge gvrpState Enables or disables the GARP VLAN Registration Protocol (GVRP), which
can help simplify management of VLAN configurations in larger
networks, and determines whether the virtual LAN (VLAN) origin for a
port-based VLAN is dynamic (with GVRP) or static (without GVRP).

Important Considerations
■
To activate GVRP in your Multilayer Switching Module, you first enable
it for the entire bridge (this command) and then enable it on
appropriate individual bridge ports (see Chapter 7).
■
To maximize the effectiveness of GVRP, it should be enabled in as
many end stations and network devices as possible.
■
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, or if GVRP is disabled, or if the module is rebooted, all
dynamic VLANs are removed.
■
If you disable GVRP after it has been enabled for a period of time, the
module deletes all VLAN interfaces that were learned through GVRP
and leaves unchanged all VLANs that were statically configured
through the Administration Console or through the Web
management software.
