Parameters
hold: Sets the hold timer.
join: Sets the join timer.
leave: Sets the leave timer.
timer-value: Timer setting (in centiseconds), which must be a multiple of 5.
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/Layer-2 aggregate interface 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.
The GVRP configuration made on a link aggregation member port can take effect only after the port
is removed from the group. For more information about link aggregation, refer to Link Aggregation
Configuration in the Access Volume.
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:
