I added an outdoor industrial POE switch, IES206GPP v1.0, to my existing Omada network. It is connected to a SG2210XMP-M2 v1.0, then to another SG2210XMP-M2 v1.0, then to my router. These are all connected via single mode fiber LC / UPC with TP Link 1G and 10G SFPs.
I noticed that after connecting the switch, after about 12-24 hours, my network connected to the SG2210XMP-M2 v1.0 slows to a crawl with almost 0 upload and about 50% download. The only fix I have found is to reboot the SG2210XMP-M2 v1.0 and then my speeds return to 100%. This occurs even with no devices plugged into the switch. It takes about 30 seconds for a speed test to load.
I have 3 VLANS. MGMT/MAIN lan which is what Omada is located on, and the port the IES206GPP is set to trunk. I can set the other ports on the IES to the other two VLANs with no issues.
Speeds directly at the router are fine. Is there some sort of table that could be filling up and requiring reset? Or is this because I added an Agile switch to a non-Agile network? It adopted fine once I changed the setting in the controller.
I’ve tried changing ports on both ends, new SFPs, turning STP on/off even though it makes no sense here, and the slowdown still happens. Any ideas? Is mixing an agile switch with a 10G switch a bad idea? I’m past the return window for this IES switch.
