CHAPTER 12

Dynamic Channel Selection

This chapter shows you how to configure and use dynamic channel selection on the NXC.

12.1 DCS Overview

Dynamic Channel Selection (DCS) is a feature that allows an AP to automatically select the

radio channel upon which it broadcasts by passively listening to the area around it and

determining what channels are currently being broadcast on by other devices.

When numerous APs broadcast within a given area, they introduce the possibility of

heightened radio interference, especially if some or all of them are broadcasting on the same

radio channel. This can make accessing the network potentially rather difficult for the stations

connected to them. If the interference becomes too great, then the network administrator must

open his AP configuration options and manually change the channel to one that no other AP is

using (or at least a channel that has a lower level of interference) in order to give the connected

stations a minimum degree of channel interference.

12.2 DCS Commands

The following table identifies the values required for many of these commands. Other input

values are discussed with the corresponding commands.

The following table describes the commands available for dynamic channel selection. You

must use the

configure terminal command to enter the configuration mode before you

can use these commands.
