field. If changes are found, and the numbers are large (compared to the Total radios field) then it
may be time to run a new analysis to optimize your network.
• Total radios: The total number of controlled radios managed by the controller (including legacy
radios).
• Enabled: The total number of controlled radios that were enabled since the last baseline was
applied. (In other words, radios that were disabled in the last baseline but are now enabled.)
• Configuration changed: Number of radios whose configuration has changed since the last
baseline was applied.
• DFS channel changed: The radio detected a radar signal and performed a channel change
for DFS reasons after the last baseline was applied.
• New radios: The number of new radios added to the controller after the last baseline was
applied.
• Disabled: The total number of radios that were disabled or deleted since last baseline was
applied. (In other words, radios that were enabled in the baseline, but that are now disabled
or have been deleted.)
• Missing neighbors: Number of neighboring radios that are no longer detected.
• New neighbors: New neighboring radios discovered since the last baseline was applied.
• Elapsed time: Indicates how long the current analysis has been running.
• Estimated time to completion: Estimated time to complete the current analysis.
• Estimated improvement so far: Estimated improvement compared to the last applied baseline.
• Highest individual AP improvement: The expected performance of each AP is estimated and
then compared to the performance of that the last applied baseline. This field then shows the
percentage improvement for the AP that improved the most.
Working with baselines
A baseline is a repository that is used to store the auto-channel and auto-power settings for all APs
managed by the controller. Baselines allow you to manage RRM settings as required to fine tune
the operation of your network. Every time an RRM analysis is run, two baselines are automatically
created in the RRM available baselines box:
• An RRM BEFORE baseline is created to capture the current channel and power settings in effect
on all controlled AP radios, and the wireless scanning data for all non-controlled neighbors.
This baseline is created, before the analysis is run.
• An RRM AFTER baseline is created to store the results of the analysis once it is complete.
These two baselines are always overwritten each time an analysis is run.
Baselines can also be created manually (up to seven of them) to save the current RRM auto-channel
and auto-power settings that are in effect, as well as all wireless scanning data for non-controlled
neighbor radios.
In the following example, three baselines have been created. The first two are the standard before
and after baselines created by running an analysis.
