I am running everything at the latest patch levels. Specifically, my CM is Version 5.2.1 and my CM Devcice Package is 6.0. Yet, the device remains"unknown":

Answer 1

The most common error for unknown devices is the SNMP community string not being set correctly. Verify that its showing up correctly under the Common Services ---> Devices and Credential Management --->Device Management --> Expand All Devices and search for the problematic device and update the credential and snmp RO and RW community strings.
Then re-run data collection and launch topology services.
If the above steps does not work, get the following information.
1. Enable debug from data collection under Campus Manager ---> Administration ---> Debugging Options --> Data Collection and select the "topo module". Also enable Debug under Campus Manager ---> Administration --> Debugging Options --> Topology and change Debug level to "trace".
2. Start a new data collection.
3. Launch Topology Map again.
4. Upload the ani.log file from CSCOpx/log/ani.log
5. From the Java Console, copy and paste the outputs to a text file.
