Port-based VLAN Overview
As explained in the VLAN Overview section earlier in this chapter, a
VLAN consists of a group of ports on one or more Ethernet switches that
form an independent broadcast domain. Traffic generated by the end
nodes of a VLAN remains within the VLAN and does not cross over to the
end nodes of other VLANs unless there is an interconnection 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 desired. The
VLAN can consist of all the ports on an Ethernet switch, or just a few
ports. A port-based VLAN also can span switches and consist of ports
from multiple Ethernet switches.
Note
The AT-8316F or AT-8324 Switch is pre-configured with one port-
based VLAN. All ports on the switch are members of this VLAN,
called the Default VLAN.
The parameters that make up a port-based VLAN are described in the
table below:
PARAMETER DESCRIPTION
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.
