Incorporating Wireless Devices into VLANs
A WLAN is generally deployed in an enterprise campus or branch office for increased efficiency and
flexibility. WLANs are one of the most effective methods for connecting to an enterprise network. With
version 12.01T1, you can configure your wireless devices to operate in a VLAN.
The basic wireless components of a VLAN consist of an access point and a set of clients associated to it
using wireless technology. The access point is physically connected through a trunk port to the network
switch on which the VLAN is configured. The physical connection to the VLAN switch is through the
access point’s Ethernet port.
