Is there a way to exclude a channel from being assigned to an AP without having to statically assign channels to all of the AP's in a large LAN?

Hi @Brian Powers​  this may be related to above. We have AP121s on 6.5r12 in NG Cloud hosted, NZ country code.

Only those APs set to Auto channel assignment allow the show acsp neighbor command to return a SSID chan list.

When changed to a static channel, the acsp neighbor list is empty.

Is is this a known limitation?

also even though the DFS range is allowed in the radio profile, the auto selection fails to ever pick a DFS chan, and results in multiple co channels which cause major cci drops.

If you're on legacy HM, the above will not be available for the 5 GHz band. But you can do a CLI Supplement and use the command

interface wifi1 radio channel exclude <channel number>

You must be running a certain code version (I forget which) and ACSP has to be running (no static) for the command to take.

Yes, if you open your Radio Profile you can set parameters around what channels your APs are going to use when they are auto selecting their own channels. To tell what Radio Profile you are currently using, you'll want to go to Monitor> Click on the host name of the AP> Go to Interface Settings on the left hand side menu> Check the Radio Profile drop down for both Wifi0 and Wifi1.

To edit your Radio Profile or to make a new one (keep in mind that default Radio Profile objects can't be edited, so make sure you aren't trying to change a default object if you're building off an existing Radio Profile), you'll want to go to Configure> Common Objects> Radio Profile (left hand side menu, under heading "Policy")> Click Add or click on the name of the object you want to edit.

Scroll down to the Channel Selection section and you choose the proper Region for the APs (this matters because different regions have different standards and requirements, so location matters when selecting a channel for your traffic to use), and then you can limit the channel select to a few pre-selected options. For example, in the the USA we should only be using 1, 6, or 11 as these are non-overlapping channels in the 2.4GHz channel range. So we can limit the channel select to only 1, 6, or 11 and leave it up to the APs to decide which is best based on their background scans and channel costs.

Once you apply this Radio Profile to the APs, you should be good to go.
