When doing RF tuning, the Summary State seems to be a good quick reference as to how the radio is performing regarding interference (good, fair, high collision) . After making radio power adjustments to APs, how long before the Summary State is recalculated or updated? Will rebooting the AP force this to recalculate?
From what I’ve read in the forums, ACSP Neighbor readings are updated by the AP as background scans are performed (default every 10 min) but I’ve yet to see if there is any way to force this or clear this. But I’m curious if the Summary State is the same.

Hey, the output for “show int wifix” is showing real time data. The possible summary states and their thresholds are:
Good: The CRC and Tx error rates are less than 5%, and channel utilization is less than 50%.
Fair: The CRC and Tx error rates are less than 10%, and channel utilization is less than 65%.
Channel RF Overcrowded: The channel utilization rate is 65% or greater.
High Collision: The CRC error rate is 10% or greater.
High Tx Error: The transmit error ration is more than 10%, which can occur when the RF environment is overcrowded and the collision rate is high.
Some other commands I typically use when I’m looking at RSSI neighbors and the interface states are “show acsp channel-info detail” and the commands to clear the LLC counters. Looking at the channel info detail will show which channels have the least amount of interference/other traffic on them, and clearing the LLC counters will give you an idea of the amount of incoming traffic on a particular radio. This guide covers both commands and how to read the output: https://extremeportal.force.com/ExtrArticleDetail?an=000079422
Is that what you were looking for?
