Figure 4-5-13 GVRP Global Setting Page Screenshot
The page includes the following fields:
Object Description

GVRP Controls whether GVRP is enabled or disabled on this switch.
 Join Timeout The interval between transmitting requests/queries to participate in a VLAN
group.
Range: 20-16375 centiseconds
Default: 20 centiseconds
 Leave Timeout The interval a port waits before leaving a VLAN group. This time should be set
to more than twice the join time. This ensures that after a Leave or LeaveAll
message has been issued, the applicants can rejoin before the port actually
leaves the group.
Range: 45-32760 centiseconds
Default: 60 centiseconds
 LeaveAll Timeout The interval between sending out a LeaveAll query message for VLAN group
participants and the port leaving the group. This interval should be considerably
larger than the Leave Time to minimize the amount of traffic generated by
nodes rejoining the group.
Range: 65-32765 centiseconds;
Default: 1000 centiseconds
Timer settings must follow this rule:
2 x (join timer) < leave timer < leaveAll timer
