VLAN Overview

This VLAN overview contains the following sections:

“VLAN Name,” next

“VLAN Identifier” on page 44

“VLAN Port Members” on page 44

“Incoming and Outgoing Tagged and Untagged Frames” on page 45

“Guidelines for Creating a VLAN” on page 46

VLAN Name To create a port-based VLAN, you must give it a name. The name should reflect the function of the network devices that are be members of the VLAN. Examples include Sales, Production, and Engineering.

VLAN Identifier

VLAN Port

Members

Every VLAN in a network must have a unique number assigned to it. This number is called the VLAN identifier (VID). This number uniquely identifies a VLAN in the switch and the network. The factory default VID is 1 for all ports.

If a VLAN consists only of ports located on one physical switch in your network, you assign it a VID different from all other VLANs in your network.

If a VLAN spans multiple switches, then the VID for the VLAN on the different switches should be the same. The switches are then able to recognize and forward frames belonging to the same VLAN even though the VLAN spans multiple switches.

For example, if you had a VLAN titled Marketing that spanned three AT-GS950/8 switches, you would assign the Marketing VLAN on each switch the same VID.

You need to specify which ports on the switch are to be members of a VLAN. A port can be specified as a member of one or more VLANs up to 255, the maximum number of VLANs supported by the switch. The factory default VID is 1. Therefore, each port is initially configured to be a member of VLAN 1, which is known as the default VLAN.

Note

The switch is preconfigured with the Default VLAN only. All ports on the switch are initially members of the Default VLAN.

If a port is assigned to be a new member of a VLAN, its membership can be defined as either tagged or untagged.
