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:

# Set the GARP join timer to 25 centiseconds, assuming that both the hold timer 
and the leave timer are using the default.

<Sysname> system-view

[Sysname] interface ethernet 1/0

[Sysname-Ethernet1/0] garp timer join 25 

garp timer leaveall timer-value

System view

timer-value: Leaveall timer setting, in the range 65 to 32765 (in centiseconds). 
Note that the setting of the leaveall timer must be a multiple of 5 and must be 
greater than the leave timer settings of all the ports.

Use the garp timer leaveall command to set the leaveall timer of GARP.

Use the undo garp timer leaveall command to restore the default. This may 
fail if the default is less than the setting of the current leave timer.

By default, the setting of the leaveall timer is 1000 centiseconds (that is, 10 
seconds).

A leaveall timer starts upon the start of a GARP application entity. When this timer 
expires, the entity sends a LeaveAll message so that other entities can re-register 
its attribute information and starts another leaveall timer at the same time.
