Configure a GARP Timer
Set GARP timers to the same values on all devices that are exchanging information using GVRP.
There are three GARP timer settings.
• Join — A GARP device reliably transmits Join messages to other devices by sending each Join message two
times. To define the interval between the two sending operations of each Join message, use this parameter. The
FTOS default is 200ms.
• Leave — When a GARP device expects to de-register a piece of attribute information, it sends out a Leave
message and starts this timer. If a Join message does not arrive before the timer expires, the information is de-
registered. The Leave timer must be greater than or equal to 3x the Join timer. The FTOS default is 600ms.
• LeaveAll — After startup, a GARP device globally starts a LeaveAll timer. After expiration of this interval, it
sends out a LeaveAll message so that other GARP devices can re-register all relevant attribute information. The
device then restarts the LeaveAll timer to begin a new cycle. The LeaveAll timer must be greater than or equal to
5x of the Leave timer. The FTOS default is 10000ms.
Example of the garp timer Command
FTOS(conf)#garp timer leav 1000
FTOS(conf)#garp timers leave-all 5000
FTOS(conf)#garp timer join 300
Verification:
FTOS(conf)#do show garp timer
GARP Timers Value (milliseconds)
----------------------------------------
Join Timer 300
Leave Timer 1000
LeaveAll Timer 5000
FTOS(conf)#
FTOS displays this message if an attempt is made to configure an invalid GARP timer: FTOS(conf)#garp timers
join 300 % Error: Leave timer should be >= 3*Join timer.
RPM Redundancy
The current version of FTOS supports 1+1 hitless route processor module (RPM) redundancy.
The primary RPM performs all routing, switching, and control operations while the standby RPM monitors the primary
RPM. In the event that the primary RPM fails, the standby RPM can assume control of the system without requiring a
chassis reboot.
