Resets RF Gain Number of radio resets due to gain changes.
Resets MTU Change Number of times the radio reset due to a change in the Maximum Transmission Unit (MTU)
value.
Resets TX Timeouts Number of radio resets due to transmission timeouts (the radio doesn’t transmit a signal within
the required time frame.)
POE-Related Resets If the radio power profile drops, an W-AP125 may not be able to support three transmit chains,
and may drop to two chains only. This parameter displays the number of resets due to this type
of power change.
External Reset Number of times the AP has been reset because it was unplugged or its reset button was
pressed.
TX Power Changes Number of times the radio’s transmission power changed.
Channel Changes Number of times the radio’s channel changed.
Radio Band Changes Number of time the radio’s band changed.
Current Noise Floor The residual background noise detected by an AP.
NOTE: 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.
Avail TX Buffers An AP has a set number of buffers which it can use to buffer frames for nonresponsive 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.
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.
Voice aware Scan
Rejects
If you enable the VoIP Aware Scan feature in the AP’s ARM profile, the AP will not attempt to
scan a different channel if one of its clients has an active VoIP call. This Voice aware scan
Rejects parameter shows the number of times the AP has rejected a scan because of the Voip
aware scan feature.
Scan Success Number of successful scans. To view scan details, use the command show ap arm scan-
times.
EIRP The value of this parameter is the transmission power level (in dBm) + the antenna gain value.
MAX EIRP The max EIRP depends on AP capability and the regulatory domain constraint for the channel
of operation. For example, in the US, Channels 36-48 have
max EIRP of 23dBm
UAPSD Flush STA Wake Number of times a client wakes from power-save mode and flushes
the UAPSD queue.
