2. The device is sending the public community string int he trap received by Spectrum
Resolution
When the Spectrum Trap Based Continuous Discovery is enabled, Spectrum first tries to model the device using the snmp community string sent with the trap.
If Spectrum is unable to create the model using the community string sent with the trap, Spectrum attempts to model the device using the community strings in the "SNMP Community Strings" list located in the AutoDiscovery Control -> Modeling and Protocol Options subview of the VNM model.
1. Check the trap to see if public is sent as the community string
2. Check the "SNMP Community Strings" list located in the AutoDiscovery Control -> Modeling and Protocol Options subview of the VNM model
