Volume 3-Layer 2 Configurations / Chapter 12-GARP VLAN Registration Protocol (GVRP) Configuration GARP Configuration Commands • Configuring the VLAN Advertisement Attribute • Verifying GVRP Settings • Displaying and Clearing the GVRP Statistic Counters Enabling the GVRP Protocol The GVRP protocol must be enabled on the Switch globally before GVRP can be enabled on an individual interface. The GVRP function can be enabled on both physical ports and port-channels. However, the user cannot configure GVRP on an individual member port of a port-channel. NOTE: The GVRP protocol can only be enabled on interfaces that are operating in trunk mode. To enable GVRP on an interface, access privileged EXEC mode and enter the following commands: Command configure terminal gvrp interface IFNAME trunk allowed-vlan VLAN-ID [,|-] gvrp end Explanation Enters global configuration mode. Enables GVRP globally on the Switch. Used to enter interface configuration mode for the interface that needs GVRP enabling. Specifies that the interface will operate in trunk mode. Enables GVRP on the interface. Exits interface configuration mode. In the following example, the user configures Ethernet interface 4.48 to be a trunk port, specifying that VLANs 3 and 6 can receive and send traffic on the interface in tagged format, and finally enables GVRP on the interface: DGS-6600:2>enable DGS-6600:15#configure terminal DGS-6600:15(config)#gvrp DGS-6600:15(config)#interface eth4.48 DGS-6600:15(config-if)#trunk allowed-vlan 3,6 DGS-6600:15(config-if)#gvrp DGS-6600:15(config-if)#end Specifying Forbidden Ports If the user specifies the gvrp forbidden option in interface configuration mode, the interface will not be able to become a member of any VLANs using the GVRP protocol.
