  • 1.  AP current EIRP and Max Tx EIRP

    Posted Jun 16, 2015 06:27 AM

    Hi,

    i set the value of 12 in the "Max TX EIRP" of my AP93, but if I check the current EIRP of this AP, I see the value of 15.

    Why the AP power level is greater than the limit that i set?

    I espect that the AP transmits at the maximum power of 12.

     

    Thanks,

    Massimo

    Please paste in a screenshot of your ARM profile.  The ARM profile should have the Min and Max TX power.

     

    Also make sure the ARM profile is assigned to the radio profile of the ap-group that your access point is in.

    Hi Colin,

    thank you for the reply. Yes, I know the things you have written and I think I have them configured properly. However I attach the "show ap config", so you can see my configuration and give me some suggestions.

    I use the 2.4GHz radio of my AP93.

    If I check the current EIRP I see this:

     

    show ap debug driver-log ap-name "AP93_F5-TC2_223" | include EIRP
    26 0.416996 wifi0: EIRP (Config: 15.0dBm, Set: 15.0dBm, AP Max: 20.0dBm, Reg Max: 19dBm), Conducted Power Set: 13.0dBm, Gain: 2.0dBm
    59 1.070018 wifi0: EIRP (Config: 15.0dBm, Set: 15.0dBm, AP Max: 20.0dBm, Reg Max: 19dBm), Conducted Power Set: 13.0dBm, Gain: 2.0dBm

     

     

    Thanks,

    Massimo

    You need to use "show ap active" to see what is the current power of the AP.

    Here is are the output of "show ap active":

     

    show ap active

    as you can see, the EIRP is 15

    EDIT:

     

    What version of ArubaOS is this?

    That is because your ARM assignment is set to "maintain" for both bands.  You need to change it to single-band for it to change channels and power

     

    Assignment                                                                   maintain          maintain           rf arm-profile "ARM-mantain-12db" / "default"
