Table 29 VLAN tab items for a single port

Item	Description
Type	Indicates the type of VLAN port (Trunk or Access port). If the
	port is a trunk port, the port is probably a member of more
	than one VLAN. If the port is an access port, the port can only
	be a member of one VLAN if there is no membership conflict.
VlanIds	The VLANIDs of which this port is a member.
DiscardUntaggedFrames	This field only applies to trunk ports. It acts as a flag used to
	determine how to process untagged frames received on this
	port. When the flag is set, the frames are discarded by the
	forwarding process. When the flag is reset, the frames are
	assigned to the VLAN specified by rcVlanPortDefaultVlanId.
DefaultVlanId	The VLAN ID assigned to untagged frames received on a
	trunk port.
