Graph Title Description
Radio 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
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 Networking
W-Series ArubaOS User Guide.
Radio 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 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 Dell Networking W-AirWave Best Practices Guide at dell.com/support/manuals
for details.
NOTE: (Dell Networking W and Cisco WLC thin APs on supported firmware versions only)
Goodput Displays the max and average goodput values. Goodput is the ratio of the total bytes
transmitted or received in the network to the total air time required for transmitting or
receiving the bytes. The air time includes the retry effort taken for both successful and
dropped frames.

Recent ARM Events Log
If this radio references an active and enabled ARM profile, and if W-AirWave is enabled as a trap host (see the Dell
Networking W-AirWave Best Practices Guideat dell.com/support/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 illustrated in Figure 72.
