Sending System Messages to a Syslog Server

To send system messages to a specied syslog server, use the following command. The following syslog standards are supported: RFC

Messages over UDP.

• Specify the server to which you want to send system messages. You can congure up to eight syslog servers.

CONFIGURATION mode

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

Restrictions for Tracking Login Activity

These restrictions apply for tracking login activity:

report login activity for a telnet session that prompts only a password.
