Which command(s) can show whether antennas are connected to access point and to which transmitter on access point (2.4 Ghz vs 5Ghz)?
If found that #show controllers d0 or d1 gives this output
....
Antenna: external, Gain: Allowed 4, Reported 4, In Use 4
.....
However the result looks not always correct. (sometimes controller without antenna showed the same as with antenna).
Please give advise(s).
