Omada controller unable to connect to AP when connected to Cisco Catalyst 3750G switch
I got a few EAP access points, and installed Omada controller on a PC running Ubuntu 22.04. The PC running Omada controller is in a server rack, and is connected to a Cisco 3750G switch. From that switch, I have a mishmash of other switches connected to it - a TrendNet TPE-082WS, a TP-Link TL-SG2216, and a NetGear Prosafe 24-port switch. The AP's are spread around throughout the building, connected to various switches. The controller did not recognize any of the access points. After a lot of frustration, I finally moved the PC running Omada Controller to the TP-Link TL-SG2216 switch, and then all of the AP's were discovered. I also connected the controller PC to the Trendnet and Netgear switches, and both of those switches worked as well. But, when the controller is connected to the Cisco 3750G, for some reason the controller can't connect to the AP's.
Any ideas as to what might be happening here?
Omada controller software is the latest - 5.13.30.8.
