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:

configure terminal

username name [privilege level]

{password encryption-type password}

line console 0

line vty 0 15

show running-config

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.

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.
