Parameter Description
Noise seen by an AP is reported as -dBm. Therefore, a noise floor
of -100 dBm is smaller (lower) than a noise floor of -50 dBm. For
most environments, the noise floor should be no greater than -80
dBm. Anything larger may indicate an interference problem which
is drowning out good signals (data) in background noise.
Dummy NF pkts on home channel
Number of noise floor readings on the home channel.
Dummy NF pkts on scan channel
Number of noise floor readings on the scan channel.
Avail TX Buffers
An AP has a set number of buffers which it can use to buffer
frames for non-responsive power save clients. The total number
of buffer frames depends upon the AP model type.
11g Protection
This parameter shows whether 802.11g protection has been
enabled or disabled.
Last TX Antenna
This parameter indicates whether the last frame transmitted was
sent on antenna 1 or antenna 0. This parameter can be useful for
troubleshooting external antennas.
Last RX Antenna
This parameter indicates whether the last frame received was via
antenna 1 or antenna 0. This parameter can be useful for
troubleshooting external antennas.
Scan Requests
Total number of scan requests received by the AP.
Scan Rejects
Total number of scan rejected by the AP.
Scan Rejects (Misc 1)
Number of scan rejects due to pending transmissions.
Load aware Scan Rejects
Load aware ARM preserves network resources during periods of
high traffic by temporarily halting scanning if the load for the AP
gets too high. The load aware Scan Rejects parameter shows
the number of times the AP has rejected a scan because of the
load aware scan feature.
PS aware Scan Rejects
If the ARM power-save aware scan feature is enabled, the AP will
not scan a different channel if it has one or more clients and is in
power save mode. The ps aware Scan Rejects parameter shows
the number of times the AP has rejected a scan because of the
power-save aware scan feature.
EAP Scan Rejects
If you enable the EAP-aware scanning feature in the AP’s ARM
profile, the AP will not attempt to scan a different channel if the
Extensible Authentication Protocol over LAN (EAPOL) exchange is
in progress with a client. This parameter shows the number of
times the AP has rejected a scan because of the EAP aware
scanning feature.
