User’s Manual of GSD-1002M
VLANs are dynamically configured based on join messages issued by host devices and propagated throughout the network.
GVRP must be enabled to permit automatic VLAN registration, and to support VLANs which extend beyond the local switch.
The GVRP Global Setting/Informations screens in Figure 4-5-13 & Figure 4-5-14 appear.

whether GVRP is enabled or disabled on this switch.
ï‚· GVRP
ï‚· Join Timeout
The interval between transmitting requests/queries to participate in a VLAN
group.
Range: 20-16375 centiseconds
Default: 20 centiseconds
ï‚· 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
ï‚· 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
