Chapter 17 Configuring GVRP
Configuring GVRP on the Switch
Setting the GARP Timers
Note The set gvrp timer and show gvrp timer commands are aliases for the set garp timer and show garp
timer commands. The aliases may be used if desired.
Note Modifying the GARP timer values affects the behavior of all the GARP applications running on the
switch, not just GVRP. (For example, GMRP uses the same timers.)
You can modify the default GARP timer values on the switch.
When setting the timer values, the value for leave must be greater than three times the join value
(leave >= join * 3). The value for leaveall must be greater than the value for leave (leaveall > leave).
If you attempt to set a timer value that does not adhere to these rules, an error is returned. For example,
if you set the leave timer to 600 ms and you attempt to configure the join timer to 350 ms, an error is
returned. Set the leave timer to at least 1050 ms and then set the join timer to 350 ms.
Caution Set the same GARP timer values on all the Layer 2-connected devices. If the GARP timers are set
differently on the Layer 2-connected devices, the GARP applications (for example, GMRP and GVRP)
do not operate successfully.
To set the GARP timer values, perform this task in privileged mode:
This example shows how to set the GARP timers and verify the configuration:
Console> (enable) set garp timer leaveall 10000
GMRP/GARP leaveAll timer value is set to 10000 milliseconds.
Console> (enable) set garp timer leave 600
GMRP/GARP leave timer value is set to 600 milliseconds.
Console> (enable) set garp timer join 200
GMRP/GARP join timer value is set to 200 milliseconds.
Console> (enable) show garp timer
Timer Timer Value (milliseconds)
-------- --------------------------
Join 200
Leave 600
LeaveAll 10000
Console> (enable)
Task Command
Step 1
Set the GARP timer values. set garp timer {join | leave | leaveall}
timer_value
Step 2
Verify the configuration. show garp timer
