Understanding the Spectrum Analysis Session Log
The spectrum analysis Session Log tab displays times the spectrum monitors and hybrid APs connected to or
disconnected from the spectrum client during the current browser session. This tab also shows changes in a hybrid
AP’s scanning channel caused by changes to the hybrid AP’s 802.11a or 802.11g radio profile or automatic channel
changes by the DFS or ARM features. The latest entry in the session log is also displayed in a footer at the bottom
of the Spectrum Monitors and Spectrum Dashboard window. When you close the browser and end your spectrum
analysis session, the session log is cleared.
The example in Figure 235 shows that a 2.4 GHz radio on hybrid AP was connected to the spectrum analysis client,
its channel changed twice, then was disconnected from the spectrum client.
