As shown in Table 20 , the value ranges for GARP timers are dependent on one another:
• If you want to set a value beyond the value range for a timer, you can change the value range by
tuning the value of another related timer.
• If you want to restore the default settings of the timers, restore the Hold timer first, and then the Join,
Leave, and LeaveAll timers.
Table 20 Dependencies of GARP timers
Timer Lower limit Upper limit
Hold 10 centiseconds No greater than half of the Join timer setting
Join No less than two times the Hold timer setting Less than half of the leave timer setting
Leave Greater than two times the Join timer setting Less than the LeaveAll timer setting
LeaveAll Greater than the Leave timer setting 32765 centiseconds
NOTE:
To keep the dynamic VLANs learned through GVRP stable, do not set the LeaveAll timer smaller than its
default value, 1000 centiseconds.
