Chapter 3 Installing the Router

Configuration Changes

chapter in the Security Configuration Guide. This document is part of the Cisco IOS software configuration documentation set that corresponds to the Cisco IOS software release installed on your Cisco hardware.

The enable secret password functionality is available for Cisco 12006 and Cisco 12406 Routers. You must enter the correct password on the system console to gain access to privileged-level commands. When you are running from the ROM monitor, you can use the enable password, depending on your boot ROM level.

For maximum security, the enable secret and the enable passwords should be different. If you use the same password for both functions during the setup process, the system accepts it but warns 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 uppercase and lowercase alphanumeric characters. A number cannot be used as the first character. Spaces, however, are valid password characters. For example, two words is a valid password. Leading spaces are ignored, but trailing spaces are recognized. Make a note of all passwords you set, and store that information in a secure location for future reference.

Protocols

For complete information on protocol configuration for your router, refer to the appropriate software configuration publications, which are listed in the “If You Need More Information” section on page 3-82.
