Antenna Rx chain status check and notification 6.4.2

In cases where a large variance is detected in the RSSI value collected by the FortiAP, an event will be recorded in the AP diagnostics as well as in the FortiGate event logs where the antenna with the suspected failure is indicated.

To access RSSI value reporting in FortiOS:
# diagnose wireless-controller wlac -c wtp FP423E3X17000000 | grep antenna
   antenna RSSI     : 42  35  29  34  (age=5)
# get wireless-controller wtp-status FP423E3X17000000 | grep antenna
   antenna RSSI     : 42  35  29  34  (age=5)

If an external antenna is removed or a low RSSI is received from one of the AP antennas, an event is triggered and updated:

# diagnose wireless-controller wlac -c wtp FP423E3X17000000 | grep antenna 
   antenna RSSI     : 38  30  25  35  (age=10)
   antenna event    : 38  30  25* 35  (age=10)

The WiFi event log contains a warning about the antenna failure:
