Chapter Administering the Wireless Device
Protecting Access to Privileged EXEC Commands
DETAILED STEPS
To disable username authentication for a specific user, use the no username name command in global
configuration mode.
To disable password checking and allow connections without a password, use the no login command in
line configuration mode.
Note You must have at least one username configured, and you must have login local set to open a Telnet
session to the wireless device. If you do not enter a username for the only username, you can be locked
out of the wireless device.
Configuring Multiple Privilege Levels
By default, 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.
This section includes this configuration information:

• Logging Into and Exiting a Privilege Level, page 304
