DFS RecurrenceThis widget displays anomalies related to radar-influenced channel changes. When an access point switches channels, the quality of service for connected clients can decrease temporarily, while repeated channel changes can degrade the client experience for extended periods of time. When an AP detects a radar pulse on the DFS channel it is using, regulations require that it switch to a non-DFS channel for at least 30 minutes. This widget identifies APs that repeatedly switch from a wireless channel within the DFS range (channels 50-144, inclusive) to a channel outside the range because it detects third party radar pulses. ExtremeCloud IQ records the DFS channels that are affected by radar pulses. Radar is usually not in use across the entire DFS channel range (50-144). If ExtremeCloud IQ determines that only a subset of the range is in use, you can disable only those channels. This allows the AP to continue to use DFS channels that are not affected by radar. If ExtremeCloud IQ determines that the entire range of DFS channels is affected, it is recommended that users completely disable DFS for the affected AP.The severity of a DFS anomaly is classified as:High - many (more than 12) radar events in the past 24 hoursMedium - Moderate (8-12) number of radar events in the past 24 hoursLow - Small (5-8) number of radar events in the past 24 hours.
