VLAN Trunking
Use the Interface > VLAN Trunking page to allow unknown VLAN groups to pass
through the specified interface.
Command Usage
◆ Use this feature to configure a tunnel across one or more intermediate switches
which pass traffic for VLAN groups to which they do not belong.
The following figure shows VLANs 1 and 2 configured on switches A and B, with
VLAN trunking being used to pass traffic for these VLAN groups across switches
C, D and E.
Figure 64: Configuring VLAN Trunking
Without VLAN trunking, you would have to configure VLANs 1 and 2 on all
intermediate switches – C, D and E; otherwise these switches would drop any
frames with unknown VLAN group tags. However, by enabling VLAN trunking
on the intermediate switch ports along the path connecting VLANs 1 and 2,
you only need to create these VLAN groups in switches A and B. Switches C, D
and E automatically allow frames with VLAN group tags 1 and 2 (groups that
are unknown to those switches) to pass through their VLAN trunking ports.
