about active VLAN members and through which port they can be reached. It thus ensures that all GVRP
participants on a bridged LAN maintain the same VLAN registration information. The VLAN registration
information propagated by GVRP includes both manually configured local static entries and dynamic
entries from other devices.
GVRP provides the following three registration types on a port:
z
Normal –– Enables the port to dynamically register and deregister VLANs, and to propagate both
dynamic and static VLAN information.
z
Fixed –– Disables the port to dynamically register and deregister VLANs or propagate information
about dynamic VLANs, but allows the port to propagate information about static VLANs. A trunk
port with fixed registration type thus allows only manually configured VLANs to pass through even
though it is configured to carry all VLANs.
z
Forbidden –– Disables the port to dynamically register and deregister VLANs and to propagate
VLAN information except information about VLAN 1. A trunk port with forbidden registration type
thus allows only VLAN 1 to pass through even though it is configured to carry all VLANs.
Protocols and Standards
GVRP is described in IEEE 802.1Q.
GVRP Configuration Task List
Complete these tasks to configure GVRP:

z
GVRP configuration made in Ethernet interface view or Layer-2 aggregate interface view takes
effect on the current interface only; .GVRP configuration made in port group view takes effect on all
the member ports in the group.
z
GVRP configuration made on a member port in an aggregation group takes effect only after the
port is removed from the aggregation group.
Configuring GVRP Functions
Before enabling GVRP on a port, you must enable GVRP globally.
