Fundamentals
What is Tag Base VLAN

VLAN membership in a tagged VLAN is determined by information within the
frames that are received on a port. The VLAN information within an Ethernet
frame is referred to as a tag which contains the VID (VLAN ID). When the switch
receives a frame with a VLAN tag, referred to as a tagged frame, the switch
forwards the frame only to those ports that share the same VID.
PVID is a Port VLAN ID that will be associated with an incoming untagged frame.

This Switch allows totally 4094 tag base VLANs to be created.
