Switch Discovery SNMP Probe Timeout Errors - But Device Scans Successfully

[Steven Parker]

Has anyone ever seen an instance of scanning a Switch in ServiceNow, it being classified and scanned successfully, but the Discovery Log also having numerous SNMP Probe timeout issues?  It eventually ends successfully after about 50 or so of these timeout errors.  See screenshot:

Is this due to all the ports on the Switch?  I did notice we are using the "use_getbulk" setting on the Probe parameters which can be seen here:

I also noticed in the ECC Queue, that most of the issues appear to be around these 3 probes (with are ironically showing 0 OIDs):

SNMP - Switch - SpanningTreeTable: 0 OIDs

SNMP - Switch - ForwardingTable: 0 OIDs

SNMP - Switch - BridgePortTable: 0 OIDs

I just want these timeout errors to stop.  ServiceNow Support has been unable to provide any insight or help on this issue.
