Chapter 9 GARP/GVRP Configuration
9-4
GVRP-supporting switches can receive VLAN registration information from other
switches and dynamically update the local VLAN registration information including the
active members and through which port those members can be reached. All the
GVRP-supporting switches can propagate their local VLAN registration information to
other switches so that the VLAN information can be consistent on all GVRP-supporting
devices in one switching network. The VLAN registration information propagated by
GVRP includes both the local static registration information configured manually and
the dynamic registration information from other switches.
GVRP is described in details in the IEEE 802.1Q standard. Quidway series switches
fully support the GARP compliant with the IEEE standards.
Main GVRP configuration includes:
z
Enabling/Disabling Global GVRP
z
Enabling/Disabling Port GVRP
z
Setting the GVRP Registration Type
In the above-mentioned configuration tasks, GVRP should be enabled globally before it
is enabled on the port. Configuration of GVRP registration type can only take effect
after the port GVRP is enabled. Besides, GVRP must be configured on the Trunk port.
Note:
z
When you configure an aggregation group, the GVRP feature configured on the
master port is unchanged, but that on the slave port is disabled.
z
When you add a port to an existing aggregation group, the GVRP feature on the port
is disabled.
z
When the master port leaves an aggregation group, the GVRP feature on both the
group and port is unchanged; when a slave port leaves an aggregation group, the
GVRP feature on the port is disabled.
z
When you configure GVRP feature on any port in an aggregation group, the
configuration is mapped to the master port of the group.
z
When you query the GVRP feature configured on any port in an aggregation group,
the returned result is about the master port of the group.
9.2.2 Enabling/Disabling Global GVRP
You can use the following command to enable/disable global GVRP.
Perform the following configurations in system view.
