Configuration Logging
You can log and view changes to the switch configuration. You can use the Configuration Change Logging
and Notification feature to track changes on a per-session and per-user basis. The logger tracks each
configuration command that is applied, the user who entered the command, the time that the command was
entered, and the parser return code for the command. This feature includes a mechanism for asynchronous
notification to registered applications whenever the configuration changes. You can choose to have the
notifications sent to the syslog.
Only CLI or HTTP changes are logged.Note
How to Use the CLI to Configure Features
Configuring the Command History
The software provides a history or record of commands that you have entered. The command history feature
is particularly useful for recalling long or complex commands or entries, including access lists. You can
customize this feature to suit your needs.
