Troubleshooting Spectrum Analysis
Verifying Spectrum Monitors Support for One Client per Radio
Each spectrum monitor radio can only send information to one client at a time. If you log into a controller and the
spectrum monitor dashboard does not display any data for the selected radio, another user may be logged in to the
controller at that time. Note that dual-radio spectrum monitors may be accessed by two clients; one client for each
radio.
Converting a Spectrum Monitor Back to an AP or Air Monitor
If you are trying to convert a spectrum monitor radio to back to AP or AM mode but the radio still comes up as a
spectrum monitor, access the command-line interface and see if that spectrum monitor appears in the output of the
show ap spectrum local-override command. If the spectrum monitor does appear in the local override profile table,
issue the command ap spectrum local-override no override ap-name <apame> spectrum-band
<spectrum-band> to remove the local override for that spectrum monitor and return the radio to AP or AM mode.
Troubleshooting Browser Issues
If you access the spectrum analysis dashboard using the Safari 5.0 browser, clicking the backspace button may return
you to the previous browser screen. Avoid using the backspace button when changing dashboard view names or chart
options.
If you are recording spectrum analysis data or playing back a spectrum analysis recording using a Mac client, do not
minimize the browser window while the recording is in progress, as that may cause the Adobe Flash player to pause.
Loading a Spectrum View
Saved spectrum view preferences may not be backwards compatible with the spectrum analysis dashboard in earlier
versions of ArubaOS. If you downgrade to an earlier version of ArubaOS and your client is unable to load a saved
spectrum view in the spectrum dashboard, access the CLI in enable mode and issue the command ap spectrum
