Instant - Min / Max Transmit power vs Min / Max power?

[chrispchikin]

Can anyone explain the difference between these two config parameters and when you would want to configure each?

RF -> ARM -> Min Transmit Power, Max Transmit Power

RF -> Radio -> Customize ARM Power Range [2.4GHZ | 5GHz] -> Min Power, Max Power

Also how to these relate to Aruba's recommended power levels from the VRDs?

The per band (2.4 / 5GHz) has been introduced recently to allow different ARM power settings per band, so you can set the power on 5 GHz slightly higher over 2.4 like advised in the VRDs.

The RF -> ARM is a global setting, so it applies to all radios.

I just tested in my lab, and what happens is that if you have set the RF -> Radio -> Customize ARM Power range, that setting will take precedence. If you have not set it for the specific band, the setting in RF -> ARM -> Min/Max transmit power will be set.

You can also set static channel+power on the AP itself in the Radio tab. That will disable ARM for that radio(s), and configure static settings.

Thanks this is exactly what I was looking for!
