We have been fighting with these every since we upgraded to 8.0.110.0. They are DFS events due to issues with Broadcom wireless cards in end user devices (my understanding anyway).
Our TAC case was open for about 8 months before I finally got a bandaid. This does not resolve the DFS admin up/operationally down issue on the radio, however, Prime won't alert on the event. I've been reading about fixes in various versions of code, but nothing successful yet. Here are the notes from my case, after changing the severity levels listed, the alerts stopped coming. "I was wondering if you can try some additional config as a workaround to our bug here. In the Administration->Settings-> Severity Configuration, we need to set the desired severity (minor, I think) for two Alarm conditions: AP radio interface down due to failure Radio administratively up and operationally down" On Thu, Sep 10, 2015 at 10:52 AM, Danny Eaton <[email protected]> wrote: > I’ve seen them on 3502’s, and 3702’s.
