Hi
I have gotten a Cisco sg300-28pp switch from my work, which was still in great shape.
I installed it, fully reset and simply configured some VLAN's, however nearly daily (sometimes twice daily) the switch and everything behind it gets unresponsive and not accessible:
http, https traffic just timeouts, accessing things behind it, access via IP directly works.
I literally tried everything and the issue always boils down to rebooting my switch, doing that seems to fix all the problems, however I currently have absolutely no idea what I could do to further debug nor what could be the issue.
Some little insight into my network: ISP Router > Opnsense > Switch > multiple Proxmox Nodes (Vlan 1) > Services on Proxmox (Vlan 20)
Huge thanks for any help!
Solved! Go to Solution.

I have not been able to test this, as the freezes sometimes do not occur for days and sometimes occur hourly.
But I can try to get the logs if the freezes appear, and report back.
Thanks anyway!

Without see any log is very hard to say anything.

@CrazyWolf13 hi, when is it getting unresponsive? after any specific change? or suddenly become unresponsive in random times?

Don't mind the fan erros, they are working just fine.

The only log I see that really seems to be a problem is "%INIT-I-Startup: Cold Startup " but this is the consequence not the cause. Rather than that, I dont see anything else. Did you see anything related to high CPU? It could be Spanning-tree loop but for that happen you should have another device on the network.
I would start thing about firmware upgrade.
08-17-2024 08:29 AM
Thanks @Flavio Miranda !
It runs on the latest firmware(1.4.11.5)
I can't really see a really high CPU usage, however yeah the UI is quite slow, but I tought that is most likely due to the age of the software.
08-17-2024 09:49 AM
If you disconnect everything from the switch and keep it up, does the reboot also occours?
08-17-2024 09:59 AM
@Flavio MirandaNot sure if I explaind correctly, sorry!
I meant, I need to manually reboot the device to get it up again, after it becomes unresponsive.
The device does not reboot by itself.
08-17-2024 10:34 AM
Sorry, I may misunderstood. I should be asking if the device also freeze if you do not connect anything on it for a period of time.
08-17-2024 10:36 AM
I have not been able to test this, as the freezes sometimes do not occur for days and sometimes occur hourly.
But I can try to get the logs if the freezes appear, and report back.

Sounds good. Hope the logs show something interesting.
