Parameters
fixed: Sets the registration type to fixed.
forbidden: Sets the registration type to forbidden.
normal: Sets the registration type to normal.
Description
Use the gvrp registration command to configure the GVRP registration type on a port (in Ethernet or
Layer-2 aggregate interface view) or all ports in a port group (in port group view).
Use the undo gvrp registration command to restore the default on a port, or on all ports in a port group
depending on the view the command is executed.
The default GVRP registration type is normal.
GVRP provides the following three registration types on a port:
Normal –– Enables the port to dynamically register/deregister VLANs, and to propagate both
dynamic and static VLAN information.
Fixed –– Disables the port from dynamically registering/deregistering VLANs or propagating
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.
Forbidden –– Disables the port from dynamically registering/deregistering VLANs or propagating
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.
Note that:
This command is only available on trunk ports.
The GVRP configuration type configuration made on a link aggregation member port can take
effect only after the port is removed from the group. For more information about link aggregation,
refer to Link Aggregation Configuration in the Access Volume.
