Displaying and Maintaining GVRP 149
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 87 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.
