In Ethernet interface view, the
subsequent configurations apply to
the current port.
In port group view, the subsequent
configurations apply to all ports in
the port group.
In Layer-2 aggregate interface view,
the subsequent configurations apply
to the Layer-2 aggregate interface
and all its member ports.
Enable GVRP on the port gvrp
Required
Disabled by default
Configure the GVRP
registration mode on the port
gvrp registration { fixed |
forbidden | normal }
Optional
The default is normal.
GVRP is mutually exclusive with service loopback.
In an MSTP network, GVRP can run on only the CIST. In addition, blocked ports on the CIST
cannot receive/send GVRP packets.
If both GVRP and remote port mirroring are used, GVRP may register the remote probe VLAN to
unexpected ports, resulting in undesired duplicates to be received by the monitor port. For more
information about port mirroring, refer to Port Mirroring Configuration in the Network Management
and Monitoring Configuration Guide .
Enabling GVRP on a Layer 2 aggregate interface enables both the aggregate interface and all
selected member ports in the corresponding link aggregation group to participate in dynamic
VLAN registration and deregistration. In addition, the GVRP 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 Layer 2 - LAN
Switching Configuration Guide .
On a GVRP-enabled trunk port, you need to configure the port trunk permit vlan all command
on the port to ensure that the traffic of all dynamically registered VLANs can pass through the port.
