Chapter 3 Installing the Cisco 10720 Internet Router Verifying the Cisco 10720 Internet Router LEDs Configuring Global Parameters Using the Setup Facility When using the setup facility or the setup command, the system prompts the user to configure global parameters for the router. Global parameters are used for controlling system-wide settings, including the following: • Host name for the router • Passwords for the enable secret, enable, and virtual terminal security parameters • Protocols used by the router Host Name The name assigned to the router must follow the rules for ARPANET host names. It must start with a letter, end with a letter or digit, and have only letters, digits, and hyphens. The name must consist of 63 or fewer characters. For more information, refer to RFC 1035, Domain Names-Implementation and Specifications. Do not expect case to be preserved. Conventions dictate that computer names appear all lowercase. For more information, refer to RFC 1178, Choosing a Name for Your Computer. Assigning Passwords The commands available at the user EXEC level are a subset of those available at the privileged EXEC level. Many privileged EXEC commands are used to set system parameters. You should password-protect these commands to prevent their unauthorized use. For information on how to establish password protection or configure privilege levels, refer to the "Configuring Passwords and Privileges" chapter in the Security Configuration Guide. The publication is located in 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 the Cisco 10720 Internet Router. Enter the correct password to gain access to privileged-level commands. When ROM monitor is active, the enable password can be used, depending on the boot ROM level. For maximum security, the enable secret and the enable passwords should be different. If the same password is used for both the enable secret and the enable functions during the setup process, the system accepts it, but issues a warning indicating that two distinct passwords should be entered. 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. Verifying the Cisco 10720 Internet Router LEDs The router LEDs are included on the access and uplink cards. The access and uplink cards each contain two sets of LEDs: • System LEDs • Status LEDs The system LEDs inform the user of the condition of the router, while the uplink or access card status LEDs inform the user of the condition or status of the card itself. 78-13062-10 Cisco 10720 Internet Router Installation and Configuration Guide 3-33
