Configure A Garp Timer - Dell S6100 Configuration Manual

Based on the configuration in the following example, the interface is not removed from VLAN 34 or VLAN 35 despite receiving a GVRP
Leave message. Additionally, the interface is not dynamically added to VLAN 45 or VLAN 46, even if a GVRP Join message is received.
Example of the gvrp registration Command
Dell(conf-if-te-1/1/1/1)#gvrp registration fixed 34,35
Dell(conf-if-te-1/1/1/1)#gvrp registration forbidden 45,46

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 Dell Networking OS 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 Dell Networking OS 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 Dell Networking OS default is
10000ms.
Example of the garp timer Command
Dell(conf)#garp timer leav 1000
Dell(conf)#garp timers leave-all 5000
Dell(conf)#garp timer join 300
Verification:
Dell(conf)#do show garp timer
