leave: Sets the leave timer.
timer-value: Timer setting (in centiseconds), which must be a multiple of 5
centiseconds.
Description
Use the garp timer command to set a GARP timer for an Ethernet port or all ports in a
port group in compliance with the timer setting dependencies shown in
Use the undo garp timer command to restore the default of a GARP timer. This may
fail if the default does not satisfy the dependencies shown in
By default, the hold timer, the join timer, and the leave timer are set to 10 centiseconds,
20 centiseconds, and 60 centiseconds.
Note that:
In Ethernet port view, these two commands apply to the current port only; in port
group view, these two commands apply to all the ports in the port group.
When restoring the default GARP timers, you are recommended to do that on the
timers in the order of hold, join, leave, and leaveall.
When configuring GARP timers, note that their values are dependent on each
other and must be a multiplier of five centiseconds. If the value range for a timer is
not desired, you may change it by tuning the value of another timer as shown in
the following table:
