1 Switch went offline other didn't why?

Simple configuration details
2x S8 POE Switches. Call them Switch 1 (1.2m) and Switch 2 (1.2m)
2x AP6-Pro, call them AP 1 (2.0g) and AP 2 (2.0g)
Each switch is a direct connection to the router, each AP has a direct connection to 1 switch.

Interesting behavior last night.
I was connected to switch 1 through AP 1, my wife was connected to switch 2 through AP 2. At some point my internet connection dropped off, eventually came back but was out for about 1-2 minutes that I noticed. During this time no impact to my wife’s connection.

Some additional notes:
I received an email alert noting the switch 1 and ap 1 were down “Alta devices have been detected offline:”.
The update of the switches and APs are in days, it didn’t go down.
I have persistent logging configured on the switch.
Checking my syslog server, can’t really see anything of substance.

Thoughts I what I can check next?

Thank you in advance

Hi,

I’ve found that my only S8 POE switch went down and wouldn’t come back up on its own without a manual power off. It’s only happened once to me so far since owning it so I haven’t really thought too much of it.

Something similar to this post: Alta Switch Stopped Working?

Would suggest taking a look at the way to configure SSH and the persistent logging.

Pulled some of the logs from the switch and looks like this switch wasn’t able to resolve to a particular host.
Will have to review if this is a local network resolution issue or something else.

@donsandro @oakserver Thanks for reporting this! Can we get ask for full logs to dive into this further, please? First we are hearing of this and not something we can replicate in labs.

(touch /cfg/.persistent.log and reboot)

Also, @oakserver curious if you have another switch between your router and your S8-POE? If so, do you see anything in the logs of that switch?
