During a new site deployment or when configuring existing site’s RF parameters, you may make the required RF changes to Tx power & channel assignment on the site from the RRM page and expect the changes to take place right away.
In order for the effect to take place right away, every RF change must be followed with an Optimize now for each of the bands (2.4GHz & 5GHz) where changes were made. Once the changes have been made, the Radio Events table will reflect these RF changes as Triggered site RRM.
