We need to disable this in our environment and currently we have to do this one ap at a time. Can we configure this via WLC so that any AP that joins will have this setting? Note that we are using C9130AXI-B AP running on 22.214.171.124 code version and WLC is 5520
Robert, were you just looking to disable the secondary 5 GHz radio and keep the primary (slot 1) turned on? The first suggestion above will disable 5 GHz entirely across all APs, so be careful.
I would like to do this, too. I tried Rasika's solution on AireOS 126.96.36.199 but only doing it on a single AP for testing:
config 802.11a dualradio ap <ap name> manual disable
It says: "Make sure to disable the slave slot while disabling the dualradio mode" and the secondary 5 GHz radio remains on.
Rasika, will this command work successfully with the global command you provided?
In the GUI, I found that the primary 5 GHz slot (slot 1) needs the "dual radio assignment" set to Manual then Disable in Wireless > Access Points > Radios > 802.11a/n/ac/ax. That works to disable slot 2 and disable dual radio and enable 8x8 on slot 1 in one step. But I'm not sure how this can be done in mass in the WLC, or automatically for all APs, as Robert asked.
It can be done in Prime with a Lightweight AP config template in two steps. First step, disable slot 2, and deploy the template:
That disables slot 2, but with dual radio mode still enabled, slot 1 still only runs in 4x4 mode with antennas A-D:
To make slot 1 8x8 using antennas A-H, deploy a second template to disable dual radio mode on Slot 1:
