Running the Carrier Busy Test

You can use the carrier busy test to determine the least conjested channel for a radio interface (802.11g or 802.11a). You should typically run the test several times over several days to obtain the best results and to avoid temporary activity spikes.

 

Note

The carrier busy test is primarily used for single access points or bridge environments. For sites with

 

 

 

 

multiple access points, a site survey is typically performed to determine the best operation location and

 

 

 

 

operating frequency for the access points.

 

 

 

 

 

 

 

 

 

 

 

Note

All associated clients on the selected radio will be deassociated during the 6 to 8 seconds needed for the

 

 

 

 

carrier busy test.

 

 

 

 

 

 

 

 

 

Perform these steps to activate the carrier busy test:

 

 

 

 

Step 1

Use your web browser to access the access point browser interface.

 

Step 2

At the prompt, enter the administrator username and password. The default username is Cisco and the

 

 

 

 

default password is Cisco. The username and password are case sensitive.

 

Step 3

Click Network Interfaces and the Network Interface Summary page displays.

 

Step 4

Choose the radio interface experiencing problems by clicking Radio0-802.11Gor Radio1-802.11A.

 

 

 

 

The respective radio status page displays.

 

Step 5

Click the Carrier Busy Test tab and the Carrier Busy Test page displays
