VLAN function
The GSWB provides a VLAN function complying with IEEE802.1Q.
A virtual LAN (VLAN) is a system that enables setting up a logical network
configuration in contrast to a conventional system that depends on a physical network
configuration.
The GSWB implements the VLAN function by using the group identification
methods referred to as the port method and the tag method. The port method
identifies groups on a per-port basis. The tag method identifies which VLAN a frame
belongs to by adding additional information referred to as a tag to the frames.
