Switch 7700 Configuration Guide

GARP/GVRP Configuration 43
Configuring GVRP GARP VLAN Registration Protocol (GVRP) is a GARP application. Based on the
GARP operating mechanism, GVRP maintains the dynamic VLAN registration
information in the switch and distributes the information to other switches. All
the GVRP-supporting switches can receive VLAN registration information from
other switches and can dynamically update the local VLAN registration
information including the active members and the port through which those
members can be reached. All the GVRP-supporting switches can distribute their
local VLAN registration information to other switches so that VLAN information is
consistent on all GVRP-supporting devices in one switching network. The VLAN
registration information 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 details in the IEEE 802.1Q standard. The Switch 7700 fully
supports the GARP compliant with the IEEE standards.
Main GVRP configuration steps include:
■ Enable or Disable Global GVRP
■ Enable or Disable Port GVRP
■ Set GVRP Registration Type
In these configuration tasks, GVRP should be enabled globally before it is enabled
on the port. Configuration of the GVRP registration type can only take effect after
the port GVRP is enabled. In addition, GVRP must be configured on the Trunk
port.
Enable or Disable Global GVRP
You can use the following command to enable or disable global GVRP.
Perform the following configurations in system view.
By default, global GVRP is disabled.
Enable or Disable Port GVRP
You can use the following commands to enable or disable GVRP on a port.
