Understanding CiscouBR10012Router Configuration

Fundamentals

This section describes the basic parameters of using passwords.

Note These sections provide minimal configuration instructions. For additional configuration information,

refer to subsequent chapters in this guide. For examples of CiscouBR10000series CMTS

configuration files, refer to the “Viewing Sample Configuration Files” section on page17.

Tip Be sure that you have appropriate addresses and values based on your network before you attempt to

configure the router. Enter the show version command to display the release of CiscoIOS software

on your router.

Using the Enable Secret and the Enable Passwords

The CiscouBR10012router is administered using the Cisco command interpreter, called the EXEC. You

must boot and log in to the router before you can enter an EXEC command.

Step1 Connect a terminal to the I/O controller console port of the CiscouBR10012router 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

Step2 Power on the CiscouBR10000series. Enter no to choose the normal operating mode of the router. The

user EXEC prompt appears:

Would you like to enter the initial dialog?[yes]: no

Setting Password Protection

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 many privileged-level EXEC commands are used to set operating parameters,

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.
