Hi Team,

I have set EIRP as 6 and 12 in g radio profile. In arm, it is as below:

ARM must be taking over. Have you created a test radio profile with ARM disabled?

Hi,

Thank you for your response. ARM is enabled so will it take EIRP from radio profile or ARM profile?

ARM should take over.

Hi,

Thank you for your quick response. May I know what is the use of EIRP in radio profile.

ARM enabled and arm profile says Max Tx EIRP.

Min Tx EIRP 15 dBm
Max Tx EIRP 18 dBm

Radio profile is as below:

Min EIRP 6 dBm
Max EIRP 12 dBm

In show ap active, it shows AP is using current EIRP as 15, is that correct? I thought it will use EIRP in radio profile which ranges between 6 to 12 dBm.

May I know what is the use of EIRP in radio profile.

Hi Team,

Please assist.

What version of ArubaOS are you running?  6.x or 8.x?  If you are running 8.x, do you have an MM?

If you are running anything without an MM, the AP uses ARM min tx and ARM max tx by default to determine the AP transmit power.  The radio profile EIRP would be used if the ARM setting was disabled.

If you are running 8.x with an MM, the radio profile min and max EIRP is used by Airmatch if you are running an MM in 8.x to determine the AP transmit power.

Have you tried after disabling ARM?

Hi Team,

Thank you for your response. I have not made any changes. I would like to know the use of it before making any changes.

My setup is of standalone. 

The ARM min and Max TX power under the rf dot11a or g profile for the radio would dictate the transmit power of an access point.

Hi,

In 6.x , EIRP is only present in ARM profile so we configure max and min EIRP. If ARP disabled, we configure the transmit EIRP i.e static. : Is that correct?

In 8.x standalone, we see max and min EIRP in radio profile and also in ARM profile, we see max Tx EIRP and min Tx EIRP. So would like to know which EIRP is used if I have standalone? 

In 8.x standalone, we see max and min EIRP in radio profile and also in ARM profile, we see max Tx EIRP and min Tx EIRP. So would like to know which EIRP is used if I have VMM-MD?

If I disable ARM in 8.x standalone and assign transmit power in radio profile, then AP takes that.

I have a standalone controller in 8.3 and would like to set max and min EIRP? Where do I have to do? 

Thank you!

Nobody disables ARM.  If you did disable ARM, all access points would be the same transmit power and channel in the radio profile.

Unless you are running an MM, the Min and Max TX in the ARM profile decides what the transmit power range for the access point is when ARM is enabled.

If you disable ARM then radio profile power setting will be used, if you enable ARM then ARM EIRP setting will be used. Don't disable ARM under any circumstances because that will create more problem then you would imagine.
