Parameter Description
Resets BeacQ Stuck An AP’s radio typically sends a beacon every 100 milliseconds. If beacons are not sent at
a regular interval or the radio experiences excessive noise, the beacon queue will reset.
This parameter indicates the number of queue resets.
Resets Fatal Intr
Number of time the radio was reset because the AP hardware was unresponsive.
Resets RX Overrun The number of radio resets due to Receive FIFO overruns.
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
