xStack® DGS-3200 Series Layer 2 Gigabit Ethernet Managed Switch VLAN Trunk Settings Enable VLAN on a port to allow frames belonging to unknown VLAN groups to pass through that port. This is useful if you want to set up VLAN groups on end devices without having to configure the same VLAN groups on intermediary devices. Refer to th e following figure fo r an illu strated ex ample. Suppose you want to create VLAN gro ups 1 and 2 (V1 and V2) on devices A and B. Without a VLAN Trunk, you must first configure VLAN groups 1 and 2 on all intermediary switches C, D and E; otherwise they will drop frames with un known VLAN group tags. However, with VLAN Trunk enabled on a port(s) in each intermediary switch, you only need to create VLAN groups in the end devices (A and B). C, D and E automatically allow frames with VLAN group tags 1 and 2 (VLAN groups that are unknown to those switches) to pass through their VLAN trunking port(s). Users can combine a number of VLAN ports together to create VLAN trunks. To create VLAN Trunk Port settings on the Switch, select the ports to be con figured, change the VLAN Trunk Global State to En abled, and click Apply, the new settings will appear in the VLAN Trunk Settings table in the lower part of the window. To view the following window, click L2 Features > VLAN Trunk Settings: Figure 3 - 22.
