Chapter 7 Configuring Switch-Based Authentication
Beginning in privileged EXEC mode, follow these steps to establish a username-based authentication
system that requests a login username and a password:
Command
Step 1 configure terminal
Step 2
username name [privilege level]
{password encryption-type password}
Step 3 line console 0
or
line vty 0 15
Step 4
login local
Step 5
end
Step 6 show running-config
Step 7
copy running-config startup-config
To disable username authentication for a specific user, use the no username name global configuration
command. To disable password checking and allow connections without a password, use the no login
line configuration command.

Purpose
Enter global configuration mode.
Enter the username, privilege level, and password for each user.
• For name, specify the user ID as one word. Spaces and quotation
marks are not allowed.
• (Optional) For level, specify the privilege level the user has after
gaining access. The range is 0 to 15. Level 15 gives privileged EXEC
mode access. Level 1 gives user EXEC mode access.
• For encryption-type, enter 0 to specify that an unencrypted password
will follow. Enter 7 to specify that a hidden password will follow.
• For password, specify the password the user must enter to gain access
to the switch. The password must be from 1 to 25 characters, can
contain embedded spaces, and must be the last option specified in the
username command.
Enter line configuration mode, and configure the console port (line 0) or
the VTY lines (line 0 to 15).
Enable local password checking at login time. Authentication is based on
the username specified in Step 2.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
