Configuring GVRP—Quick Configuration

As a network expands and the number of clients and VLANs increases, VLAN administration becomes complex, and the task of efficiently configuring VLANs on multiple EX-series switches becomes increasingly difficult. To automate VLAN administration, you can enable GARP VLAN Registration Protocol (GVRP) on the network.

GVRP learns VLANs on a particular 802.1Q trunk port, and adds the corresponding trunk interface to the VLAN if the advertised VLAN is preconfigured or existing already on the switch. For example, a VLAN named “sales” is advertised to trunk interface 1 on the GVRP-enabled switch. The switch adds trunk interface 1 to the sales VLAN if the sales VLAN already exists on the switch.

As individual interfaces become active and send requests to join a VLAN, the VLAN configuration is updated and propagated among the switches. Limiting the VLAN configuration to active participants reduces the network overhead. GVRP also provides the benefit of pruning VLANs to limit the scope of broadcast, unknown unicast, and multicast (BUM) traffic to interested network devices only.

You can use the J-Web Quick Configuration to enable or disable GVRP on an interface.

To access the GVRP Quick Configuration:

1. In the J-Web user interface, select Configuration > Quick Configuration > Switching > GVRP.

   The GVRP Configuration page displays a list of interfaces on which GVRP is enabled.

2. Click one:
   • Global Settings—Modifies GVRP timers. Enter the information as described in Table 166.
   • Add—Enables GVRP on an interface.
   • Disable Port—Disables an interface.
   • Delete—Deletes an interface.
3. Click one:
   • To apply changes to the configuration, click OK.
   • To cancel the configuration without saving changes, click Cancel.
