Channel Management

Cisco WAP571/E Administration Guide

Channel Management

The Channel Management page shows the current and planned channel 
assignments for WAP devices in a Single Point Setup cluster.

When channel management is enabled, the AP automatically assigns radio 
channels used by WAP devices in a Single Point Setup cluster. Automatic channel 
assignment reduces mutual interference (or interference with other WAP devices 
outside of its cluster) and maximizes Wi-Fi bandwidth to help maintain efficient 
communication over the wireless network.

The automatic channel assignment feature is disabled by default. The state of 
channel management (enabled or disabled) is propagated to the other devices in 
the Single Point Setup cluster.

At a specified interval, the channel manager (that is, the device that provided the 
configuration to the cluster) maps all clustered WAP devices to different channels 
and measures interference levels of the cluster members. If significant channel 
interference is detected, the channel manager automatically reassigns some or all 
of the devices to new channels per an efficiency algorithm (or automated channel 
plan). If the channel manager determines that a change is necessary, then the 
reassignment information is sent to all members of the cluster. A syslog message 
is generated as well indicating the sender device and the new and old channel 
assignments.

To configure and view the channel assignments for the Single Point Setup 
members:

STEP 1

Select the 

Single Point Setup

 > 

Channel Management

 in the navigation pane.

From the Channel Management page, you can view channel assignments for all 
WAP devices in the cluster and stop or start automatic channel management. You 
can also use the advanced settings to modify the interference reduction potential 
that triggers channel reassignment, change the schedule for automatic updates, 
and reconfigure the channel set used for assignments.

STEP  2

To start automatic channel assignment, click 

Start
