Chapter 18: Virtual LANs
Section IV: VLANs 404
Port-based VLAN Overview
As explained in the VLAN Overview section, a VLAN consists of a group
of ports on one or more Ethernet switches that form an independent
traffic domain. The unicast, broadcast, and multicast packets generated
by the end nodes of a VLAN remain within the VLAN and do not cross
over to the end nodes of other VLANs unless there is an interconnecting
device, such as a router or Layer 3 switch.
A port-based VLAN is a group of ports on a Fast Ethernet Switch that
form a logical Ethernet segment. Each port of a port-based VLAN can
belong to only one VLAN at a time.
A port-based VLAN can have as many or as few ports as needed. The
VLAN can consist of all the ports on an Ethernet switch, or a few ports. A
port-based VLAN also can span switches and consist of ports from
multiple Ethernet switches.
Note
All of the Ethernet line cards for the AT-8400 Series switch are pre-
configured with one port-based VLAN. All ports are members of this
VLAN, called the Default_VLAN.
The parts that make up a port-based VLAN are:
VLAN name
VLAN Identifier
Untagged ports
Port VLAN Identifier
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 members of the
VLAN. Examples include Sales, Production, and Engineering. The names
of the VLANs on a switch must be unique. You cannot give two VLANS
on the same switch the same name. A VLAN name can be up to 19
alphanumeric characters in length.
VLAN Identifier
Each 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.
