64 CHAPTER 3: VLAN CONFIGURATION
All the switches that support GVRP can distribute their local VLAN registration
information to other switches so that VLAN information is consistent on all GVRP
devices in the same network. The VLAN registration information that is distributed
by GVRP includes both the local static registration information that is configured
manually and the dynamic registration information from other switches.
GVRP is described in the IEEE 802.1Q standard. The Switch 7750 fully supports
GARP compliant with the IEEE standards.
GVRP configuration steps include tasks described in the following sections:
■ Enabling or Disabling Global GVRP
■ Enabling or Disabling Port GVRP
■ Setting the GVRP Registration Type
When you configure GVRP, you need to enable it globally and for each port
participating in GVRP. Similarly, the GVRP registration type can take effect only
after you configure port GVRP. In addition, you must configure GVRP on the trunk
port.
Enabling or Disabling Global GVRP
Use the following commands to enable or disable global GVRP.
Perform the following configurations in system view.
By default, GVRP is disabled on a port.
Enabling or Disabling Port GVRP
Use the following commands to enable or disable GVRP on a port.
Perform the following configurations in Ethernet port view.
You should enable GVRP globally before you enable it on the port. GVRP can only
be enabled or disabled on a trunk port.
By default, global GVRP is disabled.
Setting the GVRP Registration Type
The GVRP includes normal, fixed, and forbidden registration types (see IEEE
802.1Q).
