This is an information trap - your device is configured to send SNMP traps for configuration events. For this particular trap I would guess someone has run the "show run" or "conf t" commands on that device. If this was at 3:01 AM as the trap suggests, do you have SolarWinds NCM or other software collecting the configuation via show run?
ccmHistoryEventCommandSource.120:= commandLine(1) (1) - command was entered via the command line
ccmHistoryEventConfigSource.120:= 3 - source is the running configuration
ccmHistoryEventConfigDestination.120:= 2 - destination was command line
