I'm troubleshooting why a few of my devices are being discovered by CS Discovery, however, they are not getting discovered by Data Collection, therefore, I'm not able to see them in Campus. Below is an error in topo.log file. Can you give me a hint as to why I wouldn't see the device in Campus?
TopoSMFGenerateCdpTopology: No entry found for the device with Id xxxxx( and IP address 10.x.x.x- entry dropped.
