Symptom

it is very important that when radar events trigger a channel change, we get a clear counter for the duration of the AP uptime, that shows how many of these events have happened Currently, the counter is only displayed during the duration of the channel exclusion time (30 min), after a radar event Two asks: 1. AP should send this stat to controller, and controller should store and display on join time. (per lab testing this is happening) 2. Controller must display this counter, after the 30 min channel exclusion time problem example, after detection: Radar Information Detected Channels Channel 136 : 35 seconds ago exclusion list Times Channel 136 : 1765 seconds remaining Channel changes due to radar : 6 DFS Statistics with Cisco Integrated RF ASIC Filtered events on serving radio : 0 Filtered events on Cisco Integrated RF ASIC : 1 Triggered radar events : 0 DFS statistics last updated : 35161 seconds ago Channel Assignment Information via DCA Current Channel Average Energy : N/A Previous Channel Average Energy : N/A Channel Change Count : 0 Last Channel Change Time : 08/29/2022 12:50:33 Recommended Best Channel : 136 But after 30 min, it changes Into this: Radar Information DFS Statistics with Cisco Integrated RF ASIC Filtered events on serving radio : 0 Filtered events on Cisco Integrated RF ASIC : 0 Triggered radar events : 1 DFS statistics last updated : 1958 seconds ago ( Channel changes due to radar is lost, but present in controller table)
