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):
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.
