Turn Off Channels

[Larry Kuntz]

I have several WAPs that I would like to turn off some channels so they do not overlap.  I would like to do this from the CLI.  I looked through the various posts but could not find anything that shows how to do this from the CLI only from the GUI.  Specifically I would like to turn off Channel 11. If you would be kind enough to post how to do this showing how to do it I would greatly appreciate it. 

Thank you in advance for your help.

I guess your reason for this is that you want to limit the CCI (co channel interference) caused by your own access-points on the 2.4Ghz? This is a good initiative but before you can do this, you need to investigate the current situation. Therefor you need to do a wireless site survey so you actually know what your current channel utilization is and for which radios it is save to disable them. Do keep in mind that RRM on your WLC will react on this so some tuning on that side can be required as well. Same goes for the configured data-rates if you want to clients to motivate to roaming quicker and send management traffic faster.

The actions I described above can be complex and I would advice you to hire somebody to help you with this if you don't know what you are doing. Let them teach you so you can do it yourself next-time.

Please rate useful posts.. 🙂

Does anyone have the actual CLI commands.  The answer from Freek is not useful.  Thank you in advance for your help.

On the web gui of the WLC go to Wireless -> Access Points -> Radios -> 802.11b/g/n and hover with your cursor on the blue icon at the right of the radio you want to disable and select the option "configure". Then on the next screen set "Admin Status" to "disable". On the CLI use the command "(config 802.11b disable APNAME).

I just wanted to give you a heads up about the consequences your proposed actions will have, I'm disappointed that you give that kind of advice such a low rating...

Like somebody else said, even though you are making an specific question, disabling channels is not a good strategy because you only have a few of them for 2.4/5 on A and G. If you have a WLC and the number of adjacent AP's is significant then you should use RRM.

In fact, I am evaluating to reduce the number of channels but because of DFS and Radar Interference that our AP's are detecting not because of overlapping.
