At least once a day we get emails from cnMaestro that one or more of our APs is offline. But nothing is offline, and we can’t find any reason why cnMaestro thinks it is.
It’s always a 3 GHz AP. Some more than others, but I can’t find any pattern tying it to a certain hardware type or firmware version, or anything like high frame or CPU utilization. Obviously we have all our CBRS radios managed through cnMaestro, not all of our 5 GHz radios are, but they never have this problem. We also have ePMP links (Force 300) between buildings at customer sites, and we don’t get notifications about those unless they really are offline.
I don’t feel like this has always been a problem, but it didn’t just start recently. I’d say it’s been an annoyance for at least a year.
How does cnMaestro determine an AP is offline? Is it different for CBRS, maybe because it is acting as a proxy to the SAS? Are there configurable parameters for when to send an email notification?
Are others seeing this? At least one other WISP told me they just don’t enable email notifications. Is that the solution, just turn it off?
