How often does ARM reevaluate the radio environment?

  • 1.  How often does ARM reevaluate the radio environment?

    Posted May 04, 2022 04:31 PM

    I need to move, and possibly remove, some APs on a 4 floor building at our college. How long should I wait for ARM to reevaluate the radio environment and make any adjustments, before I do validation surveying?

    Are you sure you are using ARM and not airmatch?

    Just did some reading, and looks like Airmatch might in fact be the correct term for the radio management in use. 
    Same question then: how quickly will Airmatch adjust neighboring access points' channel or TX values, in response to rearranging or removing an AP

    Airmatch only runs once a day to change channels and power.

    Anyway to manually trigger Airmatch to do it?

    I'd like to not have to wait a day to see how changing one or two APs positions will be interpreted.

    As cjoseph mentioned, by default AirMatch pushes its updates once a day (if a change is deemed necessary). By default this occurs at 5am. You can change that time if you want.

    You can run an "on demand" optimization via the MM cli.
    airmatch runnow <option>


    The options are:
    full (the same full optimization algorithm that runs daily)
    quick (a "quick and dirty" scan of random channels to compute an updated EIRP)
    incremental (only works on new APs added since prior full run, while keeping existing settings on existing APs)

    Cody, Colin, thanks to both of you for your help.
