Dell Force10 S55T S55 Configuration Guide FTOS 8.3.5.3 - Page 269

Based on the configuration in the example shown in Figure 13-5, the interface 1/21 will not be removed from VLAN 34 or VLAN 35 despite receiving a GVRP Leave message. Additionally, the interface will not be dynamically added to VLAN 45 or VLAN 46, even if a GVRP Join message is received. Figure 13-5.

Use this parameter to define the interval between the two sending operations of each Join message. The FTOS default is 200ms. • Leave: When a GARP device expects to de-register a piece of attribute information, it will send out a Leave message and start 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: Upon startup, a GARP device globally starts a LeaveAll timer. Upon expiration of this interval, it will send 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. Figure 13-6.
