Hello, I am looking for some help discovering two switch stacks, I have discovered most of my network with problems including other 3750 Stacks. But I have two stacks that don't seem to want to get entered into APIC-EM and show partial collection. I have done the usual troubleshooting like, deleting and re-adding, trying no profile discoveries, CDP discover, single port range discovers and still nothing. The discoveries show as successful but the topology maps are showing the access switches all over the map not connected the the collapsed core stack. I have opened a TAC case and provided the RCA logs to TAC but they don't have any finding yet and I wanted to know if the communities would have any suggestions.
Here it the error message the pops up next to the status of partial collection:
All information from the device could not be collected successfully. It may be a temporary reachability problem or credentials are not correct. Please re-run the discovery for the device and if that does not resolve the problem, please get in touch with Cisco TAC to resolve your problem
