Audit log

To monitor user activity and configuration changes on the switch, enable the audit log. Only the sysadmin and secadmin roles can enable, view, and clear the audit log.

The audit log records configuration and security events, including:
  • User logins and logouts on the switch, failed logins, and concurrent login attempts by a user
  • User-based configuration changes recorded with the user ID, date, and time of the change. The specific parameter changes are not logged.
  • Establishment of secure traffic flows, such as SSH, and violations on secure flows
  • Certificate issues, including user access and changes made to certificate installation using crypto commands
  • Adding and deleting users

Audit log entries are saved locally and sent to configured Syslog servers. To set up a Syslog server, see System logging.

Enable audit log

  • Enable configuration and security event recording in the audit log on Syslog servers in CONFIGURATION mode. 
    logging audit enable

To disable audit logging, use the no logging audit enable command.

View audit log

  • Display audit log entries in EXEC mode. By default, 24 entries are displayed, starting with the oldest event. Enter reverse to display entries starting with the most recent events. You can change the number of entries that display. 
    show logging audit [reverse] [number]

Clear audit log

  • Clear all events in the audit log in CONFIGURATION mode. 
    clear logging audit

Example

OS10(config)# logging audit enable
OS10(config)# exit

OS10# show logging audit 4
