l Association Time The time at which the selected client was associated with a particular OAW-IAP.
The AOS-W Instant UI shows the client and OAW-IAP association over the last 15 minutes.
l Access Point The OAW-IAP name with which the client was associated.
Mobility information about the client is reset each time it roams from one OAW-IAP to another.
Spectrum
The spectrum link (in the Access Point view) displays the spectrum data that is collected by a hybrid AP or by an
OAW-IAP that has enabled spectrum monitor. The spectrum data is not reported to the Virtual Controller.
The spectrum link displays the following:
l Device list - The device list display consists of a device summary table and channel information for active non
Wi-Fi devices currently seen by a spectrum monitor or hybrid AP radio.
l Channel Utilization and Monitoring - This chart provides an overview of channel quality across the spectrum. It
shows channel utilization information such as channel quality, availability, and utilization metrics as seen by a
spectrum monitor for the 2.4 GHz and 5 GHz radio bands. The first bar for each channel represents the
percentage of air time used by non Wi-Fi interferers and Wi-Fi devices. The second bar indicates the channel
quality. A higher percentage value indicates better quality.
l Channel Details - When you move your mouse over a channel, the channel details or the summary of the 5 GHz
and 2.4 GHz channels as detected by a spectrum monitor are displayed. You can view the aggregate data for
each channel seen by the spectrum monitor radio, including the maximum AP power, interference and the Signal-
to-Noise and Interference Ratio (SNIR). Spectrum monitors display spectrum analysis data seen on all channels
in the selected band, and hybrid OAW-IAPs display data from the one channel they are monitoring.
For more information on spectrum monitoring, see Spectrum Monitor on page 203.
