Creating a User Name and Password for Smart Scripting
Before you run a script from the Dell Networking OS CLI, you may want to configure an additional user
name and password to use only to run scripts on a switch.
Use the user name and password to log in to a UNIX shell and apply the read-write privileges assigned to
the user name when a script runs with the script command from the Dell Networking OS CLI.
The user name is an optional keyword in the script command (refer to Scheduling Time / Event-based
Scripts). To satisfy the requirements for a UNIX BSD login, the username must be fewer than 16
characters. A username you use to run scripts cannot contain special characters.
• Create an additional user name and password that you use to log in to a shell and apply read-write
privileges when you run a script.
CONFIGURATION mode
username name password password

You are prompted to enter a user name and password before you can access the shell. Login is
performed using SSHv2.
• Access the shell to run UNIX commands or a script (refer to Running a Script from the UNIX Shell).
