Enabling or Disabling GVRP

(Global Setting)

GARP VLAN Registration Protocol (GVRP) defines a way for switches to exchange
VLAN information in order to register VLAN members on ports across the network.
VLANs are dynamically configured based on join messages issued by host devices
and propagated throughout the network. GVRP must be enabled to permit automatic
VLAN registration, and to support VLANs which extend beyond the local switch.
(Default: Disabled)

Web

– Click VLAN, 802.1Q VLAN, GVRP Status. Enable or disable GVRP, click

Apply

Figure 23-1 Globally Enabling GVRP

CLI

– This example enables GVRP for the switch.
