Enabling GVRP Globally
To configure GVRP globally, use the following command.
• Enable GVRP for the entire switch.
CONFIGURATION mode
gvrp enable
Example of Configuring GVRP
Dell(conf)#protocol gvrp
Dell(config-gvrp)#no disable
Dell(config-gvrp)#show config
!
protocol gvrp
no disable
Dell(config-gvrp)#
To inspect the global configuration, use the show gvrp brief command.
Enabling GVRP on a Layer 2 Interface
To enable GVRP on a Layer 2 interface, use the following command.
• Enable GVRP on a Layer 2 interface.
INTERFACE mode
gvrp enable
Example of Enabling GVRP on an Interface
Dell(conf-if-gi-1/21)#switchport
Dell(conf-if-gi-1/21)#gvrp enable
Dell(conf-if-gi-1/21)#no shutdown
Dell(conf-if-gi-1/21)#show config
!
interface GigabitEthernet 1/21
no ip address
switchport
gvrp enable
no shutdown
To inspect the interface configuration, use the show config command from INTERFACE mode or use the show gvrp
interface
command in EXEC or EXEC Privilege mode.
Configure GVRP Registration
Configure GVRP registration.
There are two GVRP registration modes:
• Fixed Registration Mode — figuring a port in fixed registration mode allows for manual creation and registration of VLANs,
prevents VLAN deregistration, and registers all VLANs known on other ports on the port. For example, if an interface is
statically configured via the CLI to belong to a VLAN, it should not be unconfigured when it receives a Leave PDU.
Therefore, the registration mode on that interface is FIXED.
• Forbidden Mode — Disables the port to dynamically register VLANs and to propagate VLAN information except information
about VLAN 1. A port with forbidden registration type thus allows only VLAN 1 to pass through even though the PDU carries
information for more VLANs. Therefore, if you do not want the interface to advertise or learn about particular VLANS, set the
interface to the registration mode of FORBIDDEN.
