Arm eirp config mismatch

  • 1.  Arm eirp config mismatch

    Posted Oct 06, 2016 08:48 AM

    We have configured a customers network to reduce transmit power (eirp min/max) for both 2.4 and 5.

    2.4 is set to min/max eirp 6/9

    5 is set to min/max eirp 12/15

     

    The AP`s are members of the correct AP group, the AP group has the correct arm profiles.

     

    But the APs are running totally different eirp values that configured.

     

    show ap radio-summary dot11a gives me this:

     

    <ap-name>   <ap-group>       325      <ap-ip-address>  5     AP:VHT:108+  15/23

     

    The AP listed above runs eirp min/max 15/23 instead of 12/15

     

    The result is to large cells, and overlapping channels.

     

    Anyone have any ideas as to what is wrong?

     

    Running 6.4.4.9, 7220, AP 325.

    Does show ap active show any APs outside of the limit? The 23 in that output is the regulatory maximum and not what you have configured for the arm maximum transmit power.

    In your output, both 2.4ghz APs are at a power of 6 and the 5ghz APs are at a power of 15.  They are both within your constraints:

     

    APNAME-AP01  APGRP       APIPADR  0            AP:HT:11/6/18        7            AP:VHT:40-/15/22     325      E2adK  12d:14h:31m:51s  N/A

    APNAME-AP9   APGRP       APIPADR   2            AP:HT:1/6/18         19           AP:VHT:116+/15/23    325      E2daK  10d:14h:59m:15s  N/A

     

    The 18 number on the 2.4ghz is the max EIRP for that channel in your regulatory domain, NOT the maximum power that you have configured.  The 22 and 23 number on the 5ghz is the max EIRP for that channel on that AP in that regulatory domain; NOT the max transmit you have configured in the ARM profile.
