Configuring Multiple Privilege Levels - Cisco WS-C2960-24LC-S Software Configuration Manual

Chapter 8 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.

Configuring Multiple Privilege Levels

By default, the Cisco IOS software has two modes of password security: user EXEC and privileged
EXEC. You can configure up to 16 hierarchical levels of commands for each mode. By configuring
multiple passwords, you can allow different sets of users to have access to specified commands.
For example, if you want many users to have access to the clear line command, you can assign it
level 2 security and distribute the level 2 password fairly widely. But if you want more restricted access
to the configure command, you can assign it level 3 security and distribute that password to a more
restricted group of users.

Purpose
Enter global configuration mode.
Enter the username, privilege level, and password for each user.
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.

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.
