Usage
Information
Only the system and security administrators can configure login activity tracking and view the login
activity details of other users.
If you enable user login statistics, the system displays the last successful login details of the current user,
the details of any failed login attempts by others, and if the current user’s permissions have changed
since the last login.
If you use the login statistics time-period days command to set a custom time period, the
system only reports the login statistics during that interval.
NOTE: Login statistics are not applicable for login sessions that do not use authentication on user
names. For example, the system does not report login activity for a telnet session that prompts only a
password field.
Example
When you log into the system, it displays a message similar to the following:
$ telnet 10.11.178.14
