Chapter 2 Configuring the Cisco CMTS for the First Time
Understanding Configuration Fundamentals
Using the Enable Secret and the Enable Password
The Cisco uBR7100 series router is administered using the Cisco command interpreter, called the EXEC
mode. You must boot and log in to the router before you can enter an EXEC command.
Step 1 Connect a terminal to the console port of the Cisco uBR7100 series router and establish a terminal
session. You can open a Terminal application (Hyper Terminal) on a PC as follows:
a. Connect using: Direct to Com 1
b. Set bits per second: 9600
c. Set data bits: 8
d. Set parity: none
e. Set stop bit: 1
f. Set flow control: none
Step 2 Power on the Cisco uBR7100 series router. The following prompt displays:
Would you like to enter the initial dialog?[yes]:no
Step 3 Enter no to choose the normal operating mode of the router. The user EXEC prompt displays:
Router>
Note For security purposes, the EXEC has two levels of access to commands: user EXEC mode and privileged
EXEC mode. The commands available at the user level are a subset of those available at the privileged
level.
Tip Because privileged-level EXEC commands can change the configuration of the router, password-protect
these commands to prevent unauthorized use.
At the EXEC prompt, enter one of the following two commands to set password protection:
• enable secret password (which is a very secure, encrypted password)
• enable password (which is a less secure, nonencrypted password)
To gain access to privileged-level commands, enter the desired password.
Note An enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric characters.
An enable password can contain any number of uppercase and lowercase alphanumeric characters. A
number cannot be the first character. Spaces are valid password characters; for example, “two words” is
a valid password. Leading spaces are ignored. Trailing spaces are recognized. Alphanumeric characters
are recognized as uppercase or lowercase.
Passwords should be different for maximum security. If you enter the same 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.
