Table 1-2 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.
32,765 centiseconds
In networking, the following GARP timer settings are recommended:
z
GARP hold timer: 100 centiseconds (1 second)
z
GARP Join timer: 600 centiseconds (6 seconds)
z
GARP Leave timer: 3000 centiseconds (30 seconds)
Related commands: display garp timer .
Examples
# Set the GARP Join timer to 30 centiseconds for Ethernet1/0/1.
