Cat 9800 and 9120AXI AP: Both slots in 5ghz band (Dual 5-GHz mode)

PErampas

Per default, slot0 is 2.4ghz, slot 1 is 5ghz (FRA is disabled).
I can manually set each AP to 5ghz in slot0 via:
ap name <ap-name> dot11 dual-band slot 0 band 5ghz


How can I do this for a broader range of APs. Like an entire site without touching every AP?
I can't find any coresponding settings under Tags & Profiles.

Try to understand what is defined on the controller and what is defined on the ap.  If you have made changes and the run a show run, if you don't see the changes there, you will not be able to configure that on the GUI.  Other things are defined on the ap itself, and having the command like you have, its easy to script that and run that through thousands of ap's if you had to.  Command scripts when you have to do bulk is best from the command line.

Enable FRA globally.

Use the command in privilege exex mode "ap fra revert all static 5ghz

Use "show ap fra" to verify

Once all radios are converted use "ap fra freeze " in config mode to freeze the radio's

 

Or look at a automation use case where you download all the AP names to a excel or notepad file and use python, ansible etc. to do your job.

At this point you can disable the FRA.

And since 9800 is IOS-XE you could write an EEM applet to check when an AP joins and make the change if needed.
