The default is 10 centiseconds for the
hold timer, 20 centiseconds for the
join timer, and 60 centiseconds for
the leave timer.
When configuring GARP timers, note that their values are dependent on each other and must be a
multiple of five centiseconds. If the value range for a timer is not desired, you may change it by tuning
the value of another related timer as shown in the following table:
Table 1-2 Dependencies of GARP timers
Timer Lower limit Upper limit
Hold 10 centiseconds
Not greater than half of the join
timer setting
Join Not less than two times the hold timer setting
Less than half of the leave timer

The GVRP configuration made on a link aggregation member port can take effect only after the port is
