Enabling Gvrp Globally; Enabling Gvrp On Individual 802.1Q Trunk Ports - Cisco WS-C4003 - Catalyst 4000 Chassis Switch Software Configuration Manual

Chapter 13 Configuring GVRP

Enabling GVRP Globally

You must enable GVRP globally before any GVRP processing occurs on the switch. Enabling GVRP
globally enables GVRP to perform VLAN pruning on 802.1Q trunk links. Pruning occurs only on
GVRP-enabled trunks. For information on setting the per-trunk port GVRP enable state, see the
"Enabling GVRP on Individual 802.1Q Trunk Ports" section on page
To enable dynamic VLAN creation, you must explicitly enable dynamic VLAN creation globally on the
switch as well. For information on enabling dynamic VLAN creation, see the
VLAN Creation" section on page
To enable GVRP globally on the switch, perform this task in privileged mode:
Task
Step 1
Enable GVRP on the switch.
Step 2 Verify the configuration.
This example shows how to enable GVRP and verify the configuration:
Console> (enable) set gvrp enable
GVRP enabled
Console> (enable) show gvrp configuration
Global GVRP Configuration:
GVRP Feature is currently enabled on the switch.
GVRP dynamic VLAN creation is disabled.
GVRP Timers(milliseconds)
Join = 200
Leave = 600
LeaveAll = 10000

Enabling GVRP on Individual 802.1Q Trunk Ports

Note You can change the per-trunk GVRP configuration regardless of whether GVRP is enabled globally.
However, GVRP will not function on any ports until you enable it globally. For information on
configuring GVRP globally on the switch, see the
There are two per-port GVRP states:
•
•
You can configure the static GVRP port-state on any 802.1Q-capable switch ports, regardless of the
global GVRP enable state or whether the port is an 802.1Q trunk. However, in order for the port to
become an active GVRP participant, you must enable GVRP globally and the port must be an 802.1Q
trunk port, either through CLI configuration or Dynamic Trunking Protocol (DTP) negotiation.
