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 .
z
GVRP is mutually exclusive with service loopback.
z
In an MSTP network, GVRP can run on only the CIST. In addition, blocked ports on the CIST
cannot receive/send GVRP packets.
z
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 Access Volume .
z
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 Access Volume .
z
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.
Configuring GARP Timers
Among the four GARP timers, the LeaveAll timer is configured in system view and takes effect on all
ports, while the other three are configured on a port basis.
