Port 2 receives advertisement of VID 3. (Port 2 was already statically configured for VIDs
1, 2, 3)

If a static VLAN is configured on at least one port of a switch, and that port has
established a link with another device, then all other ports of that switch will send
advertisements for that VLAN.

In the figure below, tagged VLAN ports on switch “A” and switch “C” advertise VLANs 22 and
33 to ports on other GVRP-enabled switches that can dynamically join the VLANs. A port can
learn of a dynamic VLAN through devices that are not aware of GVRP (Switch “B”.)

Ports 6 dynamically joined VLAN 33

An “unknown VLAN” is a VLAN that the switch learns of by GVRP. For example, suppose that
port 1 on switch “A” is connected to port 5 on switch “C”. Because switch “A” has VLAN 22
statically configured, while switch “C” does not have this VLAN statically configured, VLAN 22
is handled as an “Unknown VLAN” on port 5 in switch “C”. Conversely, if VLAN 22 was
statically configured on switch C, but port 5 was not a member, port 5 would become a member
when advertisements for VLAN 22 were received from switch “A”. GVRP provides a per-port
join-request option which can be configured.
