3Com 10014298 manual Enabling or Disabling Global Gvrp, By default, Gvrp is disabled on a port

64CHAPTER 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.

Table 58 Enabling/Disabling Global GVRP

Operation	Command
Enable global GVRP	gvrp
Disable global GVRP	undo	gvrp

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.

Table 59 Enabling/Disabling Port GVRP

Operation	Command
Enable port GVRP	gvrp
Disable port GVRP	undo	gvrp

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).
