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:
1 Explicit Tagging
A VLAN identifier is added to the frame header that identifies the source VLAN.
2 Implicit 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 AAM. A filtering database consists
of a static entries (Static VLAN or SVLAN table) and dynamic entries (Dynamic
VLAN or DVLAN table).
