Question: Why does the AP-125 not show “Real time FFT” when it is used as a spectrum monitor?
Product and Software: This article applies to ArubaOS 6.0 and later.
AP-12x and RAP-5WN have limited support for spectrum monitoring. Real time FFT, FFT Duty Cycle, swept spectrum, and interface source classification are not supported.
AP-105, AP-92, and AP-93 implement full support, and all the charts should work for these APs.
