"Created By" in device configuration revisions history

Products

• VMware Smart Assurance

Issue/Introduction

When device config is pulled, in history tab of Device properties, CREATED BY is available; it takes several values like below:

• EXTERNAL:snmp
• EXTERNAL:Device
• EXTERNAL:syslog
• Unknown
• <USERNAME>

Environment

NCM - 10.1.x

Resolution

• If a user schedules a push/pull from NCM or modifies the device in a Cut-Through, it would show that user in the Created By column.
• SNMP Traps and Syslog messages would show EXTERNAL. The external SNMP notification indicates that a pull of the device configuration was done because of the receipt of an SNMP trap, most likely a config change trap. There is a "comments" area in the DCS which may contain information from the trap about the user or method that was used to make the change.
• Configuration revisions marked as "Unknown" indicate changes made outside of the NCM system such as someone using telnet to connect to the device and make a change.

Additional Information

To ensure that the user is indicated for device changes, make all NCM device changes using NCM push or Cut-Thru functionality.
