802.11 Radio Counters Summary

This table appears for radios with 802.11 counters and summarizes the number of times an expected
acknowledgement frame was not received, the number of duplicate frames, the number of frames containing Frame
Check Sequence (FCS) errors, and the number of frame/packet transmission retries and failures. These aggregate error
counts are broken down by Current, Last Hour, Last Day, and Last Week time frames, as illustrated in
Figure 84:
802.11 Radio Counters Summary table
The frame- per-second rate of these and other 802.11 errors over time are tracked and compared in the 802.11
Counters graph on the same page.

Radio Statistics Interactive Graphs

Time-series graphs for the radio are displayed across a tabbed, dual-pane interface to show changes recorded at every
polling interval over time. Clients and Usage data are polled based on the AP's group's User Data Polling Period.
Channel, Noise, and Power are based on AP Interface Polling Period. 802.11 Counters data are based on the APs
group's 802.11 Counters Polling Period.
You can adjust the attributes of these graphs as follows:
Drag the horizontal slider under the graphs to move the scope of all graphs between one year ago and the current
l
time.
Drag the vertical slider between graphs to change the relative width of each.
l
The Show All link displays all of the available data series.
l
The bar-graph icon on the upper right-hand corner of each graph opens a new window and displays all data series
l
for the selected graph over the last two hours, last day, last week, last month, and last year in one page. The
graphs that display depend on the AP and/or its controller.
Select the checkbox next to any metric to remove its data from the graph. Select Collapse to remove unchecked
l
metrics from the legend, and Show All to restore them.
