Proactive Spectrum Manager (requires Level 10 permission)

Proactive Spectrum Manager views the channel spectrum from a high level and then makes channel use recommendations. The dashboard presents a goodness value for all channels and recommended channels of operation for the network. Use the dashboard to see channel goodness over the spectrum and the best available channels for 20MHz or channel-bonded (40MHz) operation on the 2.4 and 5GHz bands. The spectrum shows bar chart goodness values for all 20MHz and 40MHz channels. The higher the bar, the better the channel. If the color of the bar is grey, no observation on that channel has taken place.

You have two PSM options, View (default) and Evaluate.

View mode monitors interference, such as rogues, and displays recommendations for channel use. If you see solid green bands on every channel in the charts, either only View is enabled or Evaluate is enabled and there are no rogues on any channels.

Evaluate is disabled on all channels by default. If you enable Evaluate mode, then PSM will manage channel use (allowed by the current region) by moving devices away from channels with a specified amount of rogue activity. To enable Evaluate (requires Level 10 authentication):

  1. Click Evaluate at the top of the screen.  
  2. select one of the options from the Evaluate drop-down list:
    View turns on rogue detection, does an immediate scan, turns off rogue detection, and then displays the results.
    One Time Adapt turns on rogue detection, does a scan,turns off rogue detection, and then moves stations to recommended channels immediately
    Periodic Adapt repeats at the interval you set in the minutes value. Every x minutes, it turns on rogue detection, does a scan, turns off rogue detection, and then moves stations to recommended channels immediately.
  3. Optionally change the Evaluation Time from 120 seconds to a value of 5 - 300 seconds. Evaluation affects rogue scanning (turns it on for Evaluation Time seconds) and optionally changes
  4. Optionally change the Threshold from 25 to a value of  1 - 100 rogues. Threshold indicates a delta in goodness value between current and recommended channel that triggers a change of channel. Non-zero threshold applies to periodic adaptation.
  5. Change the Action to Adapt
  6. Optionally change the Adaption Interval from 30 to a value of either zero or 5 - 10080 seconds. (The values 1-4 seconds are not supported.) The adaptation interval determines how often channels can be automatically changed for this controller.
  7. Click Start Wizard.
  8. Confirm by clicking OK twice.

If rogue detection is not enabled on the network, PSM turns it on when needed for evaluate mode, then turns it back off. For example, if you use the option One Time Adapt, PSM turns on rogue detection, does a scan and then moves stations to recommended channels immediately. This overwrites the running config and reboots the APs (save it to make it permanent). 

Notes:  You do not change the band because this adaptation happens either everywhere or nowhere (it’s either globally off or on for all bands). Blacklisted channels such as DFS are never recommended. RS4000 and mesh radios are not supported. The more rogue devices on a channel, the lower the recommendation will be to use that channel. Do not use this feature with a multi-channel configuration.

Click Graph Help to see what the chart colors mean. Click Details on either chart to see numeric values for the green bars in the charts. A summary of rogue scanning parameters is presented at the bottom of the screen. Also, the adaptation period of a periodic adaptation is shown if one is running. The view automatically refreshes every minute.
