Defining VLAN Trunking
VLAN Trunking allows frames belonging to unknown VLAN groups to pass through the switch. VLAN Trunking is
activated by enabling VLAN Trunking on the device and defining up to 48 ports as “Uplink” ports. In addition, Ingress
Filtering must be enabled on all ports (see GVRP Setting Page ).
Th
e fo
llowing limitations are applied to the user-defined Uplink ports:
The Uplink ports can be defined only on Units 1-2 on a stacking device.
The Uplink ports can not be added to a LAG.
The Port Lock option is disabled on both ports.
Port Mirroring is disabled on both ports.
The pass through functionality applies to all VLANs that were not created on the switch, for example if only VLAN #1 is
defined on the switch, VLANs 2-4094 will pass traffic between the Uplink ports.
In the example below, the user defined ‘VLAN Trunking’ ports (Uplinks) are ports 23 and 24. In this case, the packet
belonging to VLAN 500 enters port 23, defined as one of the Uplink Ports, and therefore will be forwarded to port 24.
