HTML SET UP & DIAGNOSTIC

13 VLAN set up

13.1 Overview

VLAN is a flexible group of devices that can be located anywhere in a

network, but than can communicate as if they are on the same physical

segment.

Devices within a VLAN can only communicate directly with devices

belonging to the same VLAN. If a device belonging to VLAN 1 needs to

communicate with devices in VLAN 2, the traffic needs to pass through a

routing device or Layer 3 switch.

An Ethernet frame belonging to a particular VLAN is tagged with a code

which is the VLAN identity code.

Four VLANs are managed by each

XSLAN.

Each Ethernet port of an XSLAN

can be assigned to one of that four

VLANs.

The HTML administration server

and the serial gateway can also be

assigned to one of that four VLANs.

Each RJ45 port can be set up as “Untag” or “Tag” or “Trunk” or “All

access”.

“Untag” port

A port must be set up as “Untag” if the device connected to the port must

only communicate with devices belonging to the same VLAN.

Untagged Ethernet frames entering the port are tagged by the XSLAN

with the VLAN id code before being transmitted to the SHDSL network or

to other ports of the XSLAN.

Tagged Ethernet frames entering the port are transmitted only if they

belong to the right VLAN.

Reciprocally, Ethernet frames coming from the SHDSL network or from

other ports of the XSLAN can be transmitted to the port only if they are

tagged with the right VLAN ID code.
