Enter system view. 2. Configure the GARP LeaveAll timer. Command system-view garp timer leaveall timer-value Remarks N/A Optional. 1000 centiseconds by default. The LeaveAll timer applies to all ports. 3. Enter Ethernet interface view or Layer 2 aggregate interface interface-type interface view. interface-number N/A 4.

Configure the Leave timer. garp timer leave timer-value Optional. 10 centiseconds by default. Optional. 20 centiseconds by default. Optional. 60 centiseconds by default. As shown in Table 19, the value ranges for GARP timers are dependent on one another; use the following guidelines to configure GARP timers: • 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, followed by the Join, Leave, and LeaveAll timers.

As shown in
Table 19
, the value ranges for GARP timers are dependent on one another; use the following
guidelines to configure GARP timers:
•
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, followed by the
Join, Leave, and LeaveAll timers.
