The commands available at the user level are a subset of those available at the
privileged level. Because many privileged-level EXEC commands are used to
set operating parameters, you should password-protect these commands to
prevent unauthorized use.

systems. You must enter the correct password to gain access to privileged-level
commands. When you are running from the boot ROM monitor, the enable
password might be used depending on your boot ROM level.

password for both during the setup script, the system will accept it, but you will
receive a warning message indicating that you should enter a different password.
An enable secret password can contain from 1 to 25 uppercase and lowercase
alphanumeric characters; an enable password can contain any number of

Your IGRP autonomous system number [1]: 199
Note For complete information on IP routing and autonomous system
numbering, refer to the appropriate software configuration publications, which
are listed in the section "If You Need More Configuration Information," later in
this chapter. The Ethernet interface does not support external routing functions.
