	Untagged	Ports belonging to the specified VLAN don't tag all
		outgoing frames transmitted.

VLAN Port	Port VID	This is the VLAN ID assigned to untagged frames
		that this port received.

	Acceptable Frame	You may choose to accept both tagged and

	Ingress filtering	If set, the Switch discards incoming frames for

9.3 Port VLAN Trunking

Enable VLAN Trunking 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 the following figure. Suppose you want to create VLAN groups 1 and 2 (V1 and V2) on devices A and B. Without VLAN Trunking, you must configure VLAN groups 1 and 2 on all intermediary switches C, D and E; otherwise they will drop frames with unknown VLAN group tags. However, with VLAN Trunking 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
