SG2210XMP-M2 feeding an SG2008 v4.2 causes the SG2008 to randomly disconnect
I have an SG2210XMP-M2 as my main switch in my network. Network is managed by Software Omada controller v6.2. I bought an SG2008 v4 switch specifically because it's a full SDN switch and that it is(can be) PoE-powered.. I got everything adopted and connected correctly, firmware is the latest on both switches. It works for a while until the SG2008 randomly drops port 8 (the PD IN port), and the switch disconnects from my network. The connected clients on the SG2008 continue to communcate, albeit disconnected from the main LAN. I plugged in the 12v transformer so the SG2008 to eliminate PoE power as the issue, but the SG2008 still randomly dropped port 8. Moving the uplink to another port on SG2008 immediatley reconnects the switch to the main LAN, so it's not an issue of the SG2008 hanging or crashing. I've enabled all logging, and the only thing I see in the logs are reports of the SG2008 disconnecting, but no other alerts or events are logged to indicate why. There are no loopback or other problems reported, the switch just diconnects from the SG2210XMP-M2 like you pulled the cable. I ended up leaving the SG2008 AC powered and moved the uplink to my ER707-M2 as the SG2210XMP-M2 and SG2008 v4 clearly have a compatibility issue. My entire network is Omada-based.
2 - SG2210XMP-M2 v1.0
1 - SG2210P v5.20
1 - SG2008P v3.20
1 - SG2005P-PD v1.0
1 - SG2008 v4.20
3 - EAP723 v2.0
1 - EAP603-Outdoor v1.0
1 - EAP225-Outdoor v3.0
1 - ER707-M2 v1.20
It should also be noted that the same SG2210XMP-M2 successfully powers and communicates with the SG2005P-PD switch, as well as mulitple APs. Both SG2210XMP-M2 and the problematic SG2008 are brand new. I even swapped the SG2008 v4.20 with another brand new SG2008 v4.20 and the same disconnect problem ccurs. The only thing that misbehaves in my entire setup is what I described above.
Posting here looking for guidance and help from TP-Link as to how to proceed. I would really like to restore the SG2008 to being PoE powered by the SG2210XMP-M2, but I can't very well have multiple disconnects a day on my network.
