Spectrum Network Configuration Manager (NCM) failed to capture running configuration from a Cisco switch with the following error:

Event : Configuration Manager - Capture failed with Primary communication mode SNMP/TFTP for host running configuration file from device <Mosel Name>  of type SwCiscoIOS on landscape spectrum initiated by user System.
