If this radio references an active and enabled ARM profile, and if your AMP is enabled as a trap host (see
Dell
PowerConnect W-AirWave Best Practices Guide
at
support.dell.com/manuals
for instructions), ARM-initiated
events such as automatic channel changes, power changes, and mode changes are displayed in the ARM Events
table with the original and modified values; these values can be selected for filtering the results. You can export
the table in CSV format. The columns and values are described in , and illustrated in
Figure 86

Power
A line graph that displays the average and maximum radio transmit power, between 0 and 30 dBm, over
the time range set in the slider. You can adjust the transmit power manually in the
APs/Devices > Manage
page for this radio's AP, or enable ARM on Dell PowerConnect W-Series APs to dynamically adjust the
power toward your acceptable Coverage Index as needed. For more information, see the "Adaptive Radio
Management" chapter of the
Dell PowerConnect W-Series ArubaOS User Guide
at

.
MAC/Phy Errors
A line graph displaying the frame reception rate, physical layer error rate (resulting from poor signal
reception or broken antennas), and the data link (MAC) layer (corrupt frames, driver decoding issues) for
the radio.
802.11 Counters
A line graph that displays statistics such as frame rate, fragment rate, retry rate, duplicate frame rate, and
other metrics tracked by 802.11 counters.
Utilization
(Dell
PowerConnect W-
Series and Cisco WLC

Displays max and average percentages on this radio for busy, interfering receiving and transmitting
signals. Special configuration on the controller is required to enable this data; consult the
