GVRP manages the active topology, not nontopological data such as
VLAN protocols. If a local bridge needs to classify and analyze packets
by VLAN protocols, you must manually configure protocol-based
VLANs and simply rely on GVRP to send VLAN ID updates. But if the
local bridge needs to know only how to reach a given VLAN, then
GVRP provides all necessary information.
The VLAN topologies that GVRP learns are treated differently from
VLANs that are statically configured. Although static updates are
saved in nonvolatile RAM, GVRP's dynamic updates are not. When
GVRP is disabled, the system deletes all VLAN interfaces that were
learned through GVRP and leaves unchanged all VLANs that were
configured through the Administration Console or through the Web
management software.
For more information about bridging, STP, and GVRP consult the
following standards:
IEEE 802.1D — This standard specifies the requirements to which
your system, as a transparent bridge, complies.
IEEE 802.1Q — This standard defines GVRP, tagging, and the dynamic
registration of VLANs.
