5.8.3 garp timer

The garp timer interface configuration command adjusts 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

ƒ join — Indicates the time in milliseconds that PDUs are transmitted. (Range: 10-2147483640)

ƒ 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. (Range: 10-2147483640)

ƒ leaveall — Used to confirm the port within the VLAN. The time in milliseconds between messages

sent. (Range: 10-2147483640)

ƒ 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 for the various timer values must be maintained:

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 application will not operate successfully.

As the number of dynamic VLANs (GVRP) increases, the leave time should be increased from the default

value.

For example, if the number of dynamic VLANs is 400, it is recommended to increase the leave time.

Example

The following example sets the leave timer for port e8 to 900 milliseconds.

Console (config)# interface ethernet e8
