in INTERFACE mode, as shown in
Figure 17-4 . Use
show config

Configuring GVRP Registration
• Fixed Registration Mode : Configuring a port in fixed registration mode allows for manual creation
and registration of VLANs, prevents VLAN de-registration, and registers all VLANs known on other
ports on the port. For example, if an interface is statically configured via the CLI to belong to a VLAN,
it should not be un-configured when it receives a Leave PDU. So, the registration mode on that
interface is FIXED.
• Forbidden Mode : Disables the port to dynamically register VLANs, and to propagate VLAN
information except information about VLAN 1. A port with forbidden registration type thus allows
only VLAN 1 to pass through even though the PDU carries information for more VLANs. So, set the
interface to the registration mode of FORBIDDEN if you do not want the interface to advertise or learn
about particular VLANS.
