Track Login Activity
Dell Networking OS enables you to track the login activity of users and view the successful and unsuccessful login events.
When you log in using the console or VTY line, the system displays the last successful login details of the current user and the number of
unsuccessful login attempts since your last successful login to the system, and whether the current user’s permissions have changed since
the last login. The system stores the number of unsuccessful login attempts that have occurred in the last 30 days by default. You can
change the default value to any number of days from 1 to 30. By default, login activity tracking is disabled. You can enable it using the
login statistics enable command from the conguration mode.
Restrictions for Tracking Login Activity
These restrictions apply for tracking login activity:
Only the system and security administrators can congure login activity tracking and view the login activity details of other users.
Login statistics is not applicable for login sessions that do not use user names for authentication. For example, the system does not
report login activity for a telnet session that prompts only a password.
