Chapter7 Configuring Switch-Ba sed Authentication Protecting Access to Privileged EXEC Comman d s
Beginning in privileged EXEC mode, follow these steps to establish a username-based authentication
system that requests a login username and a password:
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 co mm and s.
For example, if you want many users to have access to the clear line command, you can assign it
level2 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.
These sections contain this configuration information:

the VTY lines (line 0 to 15).
Step4 login local Enable local password checking at login time. Authentication is bas ed o n
the username specified in Step 2.
Step5 end Return to privileged EXEC mode.
Step6 show running-config Verify your entries.
