LMS 3.2 Topology Services shows incorrect cdp information

Answered Question

Hello,


I notice some discrepances in topology services. For example, hsee-dcn-rack31 (port 1/47) is connect to hsee-dcn-core1 (port 6/37) but the topology services show the port is 6/36. I attach topology services screenshot and cdp command outputs.


What could be the problem?


Thanks

Delete them from Topology Services, then perform a new, full Data Collection.

Nothing was attached.  Was the switch ever connected on port 6/36?

What about the answer to my question?  Was this switch ever connected on 6/36?

Post SNMP Walks of the cdpCacheTable and ifTable from both devices.

This checks out.  My theory is that Data Collection is not completing properly.  Run a new Campus Data Collection, then post the ani.log.

Data Collection seems to be completing.  Delete these two switches from the Campus map, then run a new Data Collection.  See if the proper CDP relationship shows up.
