Displaying and Maintaining GVRP 157
The following table describes the relations between the timers:
n
The recommended settings of GARP timers
■ GARP Hold timer: 100 centiseconds (1 second).
■ GARP Join timer: 600 centiseconds (6 seconds).
■ GARP Leave timer: 3000 centiseconds (30 seconds).
■ GARP LeaveAll timer: 12000 centiseconds (2 minutes).
Displaying and
Maintaining GVRP
After the above configuration, you can use the display commands in any view to
display the configuration information and operating status of GVRP/GARP, and
thus verify your configuration. You can use the reset command in user view to
clear GARP statistics.
Table 96 Relations between the timers
Timer Lower threshold Upper threshold
Hold 10 centiseconds This upper threshold is less than or equal
to one-half of the timeout time of the Join
timer. You can change the threshold by
changing the timeout time of the Join
timer.
Join This lower threshold is greater
than or equal to twice the
timeout time of the Hold timer.
You can change the threshold by
changing the timeout time of the
Hold timer.
This upper threshold is less than one-half
of the timeout time of the Leave timer.
You can change the threshold by changing
the timeout time of the Leave timer.
Leave This lower threshold is greater
than twice the timeout time of
the Join timer. You can change
the threshold by changing the
timeout time of the Join timer.
This upper threshold is less than the
timeout time of the LeaveAll timer. You
can change the threshold by changing the
timeout time of the LeaveAll timer.
LeaveAll This lower threshold is greater
than the timeout time of the
Leave timer. You can change
threshold by changing the
timeout time of the Leave timer.
