GVRP Commands

Dell™ PowerConnect™ 3324/3348 Switch CLI Guide

gvrp enable (global)

GVRP, or GARP VLAN Registration Protocol, is an industry-standard protocol designed to circulate VLAN information from device to device. With GVRP, a single switch is manually configured with all desired VLANs for the network, and all other switches on the network learn these VLANs dynamically.

The gvrp enable global configuration command enables GVRP globally. To disable GVRP globally on the switch, use the no form of this command.

Syntax

gvrp enable

no gvrp enable

Default Configuration

GVRP is globally disabled.

Command Mode

Global Configuration Mode

User Guidelines

There are no user guidelines for this command.

Example

The following example globally enables GVRP on the device.

Console (config)# gvrp enable

gvrp enable (interface)

The gvrp enable interface configuration command enables GVRP on an interface. To disable GVRP on an interface, use the no form of this command.

Syntax

gvrp enable

no gvrp enable

Default Configuration

GVRP is disabled on all interfaces by default.

Command Mode

Interface Configuration (Ethernet, port-channel) Mode

User Guidelines

The default port state is access, which is a port that belongs to a single, untagged VLAN. GVRP cannot join a port with state as access. To modify the port state, see the command switchport mode.

Example

The following example enables GVRP on port 1/e8.

Console (config)# interface ethernet 1/e8 Console (config-if)# gvrp enable

garp timer

Use the garp timer interface configuration command to adjust the GARP application join, leave, and leaveall GARP timer values. To reset the timer to default values, use the no form of this command.

Syntax

garp timer {join | leave | leaveall} timer_value

no garp timer

• join—Indicates the time in milliseconds that PDUs are transmitted.
  
  
• leave—Indicates the amount of time in milliseconds that the device waits before leaving its GARP state. The leave time is activated by a leave all time message sent/received, and cancelled by the Join message.
  
  
• leaveall—Used to confirm the port within the VLAN. The time in milliseconds between messages sent.
  
  
• timer_value—Timer values in milliseconds.
  
  

Default Configuration

The default timer values are as follows:

• Join timer—200 milliseconds
  
  
• Leave timer—600 milliseconds
  
  
• Leavall timer—10000 milliseconds
  
  

Command Mode

Interface Configuration (Ethernet, port-channel) Mode

User Guidelines

The following relationship must be maintained for the various timer values:

• Leave time must be greater than or equal to three times the join time.
  
  
• Leaveall time must be greater than the leave time.
  
  

Set the same GARP timer values on all Layer 2-connected devices. If the GARP timers are set differently on Layer 2-connected devices, GARP applications will not operate successfully.

Example

The following example sets the leave timer for port 1/e8.

Console (config)# interface ethernet 1/e8 Console (config-if)# garp timer leave 900

gvrp vlan-creation-forbid

Use the gvrp vlan-creation-forbid interface configuration command to disable dynamic VLAN creation. To enable dynamic VLAN creation, use the no form of this command.

Syntax

gvrp vlan-creation-forbid

no gvrp vlan-creation-forbid

Default Configuration

Dynamic VLAN creation is enabled by default.

Command Mode

Interface Configuration (Ethernet, port-channel) Mode

User Guidelines

There are no user guidelines for this command.

Example

The following example disables dynamic VLAN creation on port 1/e8.

Console (config)# interface ethernet 1/e8 Console (config-if)# gvrp vlan-creation-forbid

gvrp registration-forbid

Use the gvrp registration-forbidden interface configuration command to de-register all VLANs and prevent dynamic VLAN registration on the port. To allow dynamic registering for VLANs on a port, use the no form of this command.

Syntax

gvrp registration-forbid

no gvrp registration-forbid

Default Configuration

Dynamic registering and deregistering for each VLAN on the port is allowed.

Command Mode

Interface Configuration (Ethernet, port-channel) Mode

User Guidelines

There are no user guidelines for this command.

Example

The following example shows how default dynamic registering and deregistering is forbidden for each VLAN on port 1/e8.

Console (config)# interface ethernet 1/e8 Console (config-if)# gvrp registration-forbid

clear gvrp statistics

Use the clear gvrp statistics global configuration command to clear all the GVRP statistics information.

Syntax

clear gvrp statistics [ethernet interface | port-channel port-channel-number]

• interface—An ethernet interface
  
  
• port-channel-number—A port-channel index
  
  

Default Configuration

This command has no default configuration.

Command Mode

Privileged EXEC Mode

User Guidelines

There are no user guidelines for this command.

Example

The following example clears all the GVRP statistics information on port 1/e8.

Console # clear gvrp statistics ethernet 1/e8

show gvrp configuration

Use the show gvrp configuration privileged EXEC command to display GVRP configuration information, including timer values, whether GVRP and dynamic VLAN creation is enabled, and which ports are running GVRP.
