Starting with Cisco IOS 12.3(4)T, an administrator can configure a router with a series of commands such that any subsequent configuration commands entered will be sent to syslog. Having a recorded audit trail of changes made can provide a valuable tool to troubleshoot possible unexpected outcomes


This will then capture the command typed is such syslog event:
