I am a little fuzzy on this part, but I think cnMaestro does all the tricks it can to keep from withdrawing a grant once issued. I suspect if the SAS is unreachable or not responding, cnMaestro may do some kind of holdover like you mentioned. The problem is if the SAS responds but with garbage or something that looks like it is withdrawing the authorization.
As far as using more than one SAS, I think that is a firm no, unless you used one for part of your network and another for the rest of your network. When the heartbeats fail, the SMs will keep registering for a few seconds at a time so they can still communicate with the AP. And yes you can go back to Part 90 operation, but I don't think you will be able to use 3550-3650. If an extended outage happened, you could probably get customers back online that way, albeit with reduced performance. -----Original Message----- From: AF <[email protected]> On Behalf Of Adam Moffett Sent: Thursday, April 30, 2020 10:24 AM To: [email protected] Subject: Re: [AFMUG] anybody else having SAS problems this morning? I don't know who assured you that outages wouldn't happen, but that seems like an irresponsible claim. Was it the vendor sales channel? On the other hand there are clearly ways to make a service bullet proof. When was the last time Google DNS was down? Is SAS Redundnacy possible? Like could Cambium set you up with both Federated and Google and fallback if one fails? Would the FCC be amenable to a 1 hour holdover if the SAS is unreachable? I'm just throwing ideas out there. I'm not asking if we can sanitize the bugs out of the SAS with disinfectant or anything as dumb as that I hope.
