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-overridecommand. 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
