AP Performance Tab
Note: In the Performance tab, data is only available for Authorized devices.
The AP Performance tab enables you to view the data related to performance of an AP in chart form.
MAC/Protocol: Select the MAC/Protocol from the drop-down list and the relevant performance information of the
selected BSSID is displayed. MAC/Protocol field appears only for merged APs.
Line Charts are shown on the Performance Tab. Choose one of the Chart types available from the Select Chart drop-
down list:
Associated Clients: Sensor samples the number of associations with the AP at the end of each time interval.
Average Data Rate: Sensor keeps track of transmission rates of data frames in the AP’s BSS and reports
weighted average transmission rate over each time interval.
Traffic: Sensor reports data traffic sent and received by the AP over each time interval. The channel-rotating
Sensor spends only a fraction of total time on any given channel; therefore this parameter typically
underestimates the actual traffic by a factor equal to the total number of channels scanned by the Sensor
radio. For example, if b/g radio on the Sensor scans 11 channels in all, the measured traffic could be about
1/11th of the actual traffic if the traffic is continuous. Similarly, if a radio on the Sensor scans 30 channels in
all, the measured traffic could be about 1/30th of the actual traffic. However, if the traffic comes in bursts,
straightforward scaling as above cannot be applied.
Utilization: Sensor keeps track of cumulative time occupancy of frames in the AP’s BSS and reports the
cumulative time occupancy as percentage of total scan time on the channel in each time interval.
