Chapter 32 Configuring GVRP
32.1 Introduction
GVRP (GARP VLAN Registration Protocol GARP VLAN) is a GARP (GARP VLAN Registration Protocol GARP
VLAN) application that provides IEEE 802.1Q-compliant VLAN pruning and dynamic VLAN creation on 802.1Q
trunk ports.
With GVRP, the switch can exchange the VLAN configuration information with the other GVRP
switches, prune the unnecessary broadcast and unknown unicast traffic, and dynamically create
and manage the VLANs on the switches that are connected through the 802.1Q trunk ports.
32.2 Configuring Task List
32.2.1 GVRP Configuration Task List
 Enabling/Disabling GVRP Globally
 Enabling/Disabling GVRP on the Interface
 Monitoring and Maintenance of GVRP
32.3 GVRP Configuration Task
32.3.1 Enabling/Disabling GVRP Globally
Perform the following configuration in global configuration mode.
Command Description
[no] gvrp
Enables/disables GVRP globally.
It is disabled by default.
32.3.2 Dynamic VLAN to Validate only on a Registered Port
Run the following commands in global configuration mode:
Command Description
[no] gvrp dynamic-vlan-pruning
Enable/disable VLAN to validate only on a
registered port.
After this function is enabled, dynamic VLAN takes effect only on the ports on which this dynamic VLAN is
registered. After this command is enabled and if a port has not registered a dynamic VLAN, this port will not
belong to the dynamic VLAN even though this port is a trunk port and it allows the dynamic VLAN to pass
through.
The function is disabled by default.
32.3.3 Enabling/Disabling GVRP on the Interface
Perform the following configuration in interface configuration mode:
Command Description
