    Hi,

    can anybody help me  to find the signal strength in dbm for an running Accesspoint 105 with ARM enabled.

    I have used the folloowing cli command -- #show ap arm history ap-name xxxx-ap1 

     

    Output:

    Interface :wifi0

    ARM History

    -----------

    Time of Change       Old Channel  New Channel  Old Power  New Power  Reason

    --------------       -----------  -----------  ---------  ---------  ------

    2013-10-25 16:04:54  132+         36+          24         24         I

    2013-10-21 13:11:40  132+         132+         21         24         P+

    2013-10-21 13:07:12  132+         132+         18         21         P+

    ....................

    I: Interference, R: Radar detection, N: Noise exceeded, E: Error threshold exceeded, INV: Invalid Channel, G: Rogue AP Containment, M: Empty Channel, P+: Increase Power, P-: Decrease Power, OFF: Turn off Radio,

     

    What is the value from Old/New Power for a definition -- is that DB, DBM, mWatt ............

     

    Many thanks for your help.

    Cheers Roland

    "show ap arm rf-summary ap-name <your ap name>" will show you the current arm assignment which will include the channel and power in dbm.

    If you run the following command you could see it :

    The EIRP is in dB 

    show ap active
