This indicates whether the last configuration save for the associated file was triggered via SNMP or initiated from a remote device such as CLI or console access. Admins use it to audit how configuration changes were saved -- distinguishing automated management-platform saves from a technician's manual save -- when tracking down who or what changed a switch's config. A value of snmp(1) tells an admin the save was triggered by an SNMP set rather than someone typing "save" at the console.
