27.6 IEEE 802.1Q Tagged VLAN Overview

See the web configurator chapter on VLAN for more information on VLANs. There are two kinds of tagging:

1Explicit Tagging

A VLAN identifier is added to the frame header that identifies the source VLAN.

2Implicit Tagging

The MAC (Media Access Control) number, the port or other information is used to identify the source of a VLAN frame.

The IEEE 802.1Q Tagged VLAN uses both explicit and implicit tagging.

27.7 Filtering Databases

A filtering database stores and organizes VLAN registration information useful for switching frames to and from the MSAP2000 AAMS. A filtering database consists of a static entries (Static VLAN or SVLAN table) and dynamic entries (Dynamic VLAN or DVLAN table).
