Automatic VLAN registration— GARP VLAN Registration Protocol
(GVRP) defines a system whereby the switch can automatically learn
the VLANs to which each end station is assigned. If an end station (or
its network adapter) supports the IEEE 802.1Q VLAN protocol, it can be
configured to broadcast a message to your network indicating the VLAN
groups it wants to join. When the switch receives these messages, it
automatically places the receiving port in the specified VLANs and then
forwards the message to all other ports. When the message arrives at
another switch that supports GVRP, it also places the receiving port in
the specified VLANs and passes the message on to all other ports.
VLAN requirements are propagated in this way throughout the network,
allowing GVRP-compliant devices to be automatically configured for
VLAN groups based solely on end-station requests.
The following figure illustrates how you can you port-based VLANs.
Using port-based VLANs
To implement GVRP in a network, first add the host devices to the required
VLANs (using the operating system or other application software) so that
these VLANs can be propagated onto the network. For both the edge
switches attached directly to these hosts and the core switches in the
network, enable GVRP on the links between these devices. Also, determine
security boundaries in the network and disable GVRP on ports to prevent
advertisements being propagated, or forbid ports from joining restricted
VLANs.
