Performing a Basic Configuration of the Cisco 7513
This chapter describes the procedures for performing a basic configuration of your router, and contains the following sections:
To configure the Cisco 7513 from a console, you need to connect a terminal to the router's console port. Configuration requires access to the console port on a Route Switch Processor (RSP2) in your router.
This chapter guides you through a basic router configuration, which is sufficient for you to access your network. Complex configuration procedures are beyond the scope of this text, and can be found in the configuration publications listed in the section "If You Need More Configuration Information."
The Cisco Internetwork Operating System (Cisco IOS) software running the router contains extensive features and functionality. The effective use of many of many of these features is easier if you have more information at hand. To obtain general information about documentation, call Customer Service 800 553-6387 or 408 526-7208. Customer Service hours are 5:00 a.m. to 6:00 p.m. Pacific time, Monday through Friday (excluding company holidays). You can also send e-mail to
cs-rep@cisco.com
. You can also refer to the Cisco Information Packet that shipped with your router.
For additional information on configuring the Cisco 7513 router, the following documentation resources are available to you:
When all interfaces are connected, perform a final check of all connections, then power up the router as follows:

--- System Configuration Dialog --- At any point you may enter a questions mark `?' for help. Refer to the `Getting Started' Guide for additional help. Default settings are in square brackets `[]'. continue with configuration dialog? [yes]:
Many of the interface processor LEDs will not go on until you have configured the interfaces. In order to verify correct operation of each interface, complete the first-time startup procedures and configuration, then refer to the LED descriptions in the appendix "Reading LED Indicators" in the Cisco 7513 Hardware Installation and Maintenance publication to check the status of the interfaces.
If the system does not complete each of these steps, proceed to the chapter "Troubleshooting the Installation," in the Cisco 7513 Hardware Installation and Maintenance publication, for troubleshooting recommendations and procedures.
Bits 0 through 3 of the software configuration register form the boot field. The boot field specifies a number in binary and functions as follows:
You can enter the boot command only, or include additional boot instructions with the command such as the name of a file stored in Flash memory or a file that you specify for booting from a network server. If you use the boot command without specifying a file or any other boot instructions, the system boots from the default Flash image (the first image in onboard Flash memory). Otherwise, you can instruct the system to boot from a specific Flash image (using the boot system flash filename command), or boot from a network server by sending broadcast TFTP requests (using the boot system filename command), or send a direct TFTP request to a specific server (using the boot system filename address command).
The boot command can also be used to boot images stored in the Personal Computer Memory Card International Association (PCMCIA) Flash memory cards located in slot 0 or slot 1 on the RSP2. If you set the boot field to any bit pattern other than 0 or 1, the system uses the resulting number to form a filename for netbooting.
To form this filename, the system starts with cisco and links the octal equivalent of the boot field value and the processor type in the following format: cisco<bootfieldvalue>-<processorname>; for example, cisco2-RSP.
The system uses the filename to invoke the system image by netbooting. However, if the configuration file contains any boot instructions, the system uses those boot instructions instead of the filename it computed from the configuration register settings. You must set the boot field for the boot functions you require.
For more detailed information on the software configuration register features and Flash memory card functionality, refer to the Cisco 7513 Hardware Installation and Maintenance publication. For information on the boot command and function, refer to the section "Booting the Cisco 7513 for the First Time."
The router 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. For security purposes the EXEC has two levels of access to commands, user EXEC mode and privileged EXEC mode. To enter the privileged mode you must enter the enable secret password (which is optional, but must first have been saved in memory) on systems running Cisco Internetwork Operating System (Cisco IOS) Release 10.2(3) or later, or the enable password on systems running Cisco IOS releases prior to Release 10.2(3) or when using the boot ROM software. Because the Cisco 7513 requires Cisco IOS Release 10.3(6) or later, the enable and enable secret password functionality is available.
At the ROM monitor prompt, view what is in onboard Flash memory using the following:
rommon 1 > dir bootflash: File size Checksum File name 3277967 bytes (0x32048f) 0x6b331e30 rsp-k-m.103-8 rommon 2 >
Also, view the Flash memory PCMCIA card in slot 0 or slot 1 using the following:
rommon 2 > dir slot0: File size Checksum File name 3054276 bytes (0x2e9ac4) 0x97788495 rsp-k-m.103-8 rommon 3 >
Boot from one of these images using the following:
rommon 3 > boot slot0:rsp-k-m.103-8
or...
rommon 3 > boot slot1:rsp-k-m.103-8
or...
rommon 3 > boot bootflash:rsp-k-m.103-8
If you did not change the configuration register setting, the next reload will go back to the default configuration register setting. The factory default configuration register setting for systems is 0x102, and for RSP spares the default is 0x101.
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.
There are two commands you can use to do this, depending on which release of the Cisco IOS software you have:
The enable and enable secret password functionality is available in all Cisco IOS releases for the Cisco 7513. You must enter the correct password to gain access to privileged-level commands. When you are running from the boot ROM, the enable password might be used depending on your ROM level.
The 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.
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. In both cases, a number cannot be the first character. Spaces are also valid password characters; for example, "two words" is a valid password. Leading spaces are ignored; trailing spaces are recognized.
You can a complete a basic configuration of the Cisco 7513 using one of the procedures described in the following sections:
Follow the procedure that best fits the needs of your network configuration.
Before continuing the configuration process, check the current state of the router by entering the show version command. The show version command will display the release of Cisco IOS software that is available on the router.
The AutoInstall process is designed to configure the router automatically after connection to your wide-area network (WAN). For AutoInstall to work properly, a Transmission Control Protocol/Internet Protocol (TCP/IP) host on your network must be preconfigured to provide the required configuration files. The TCP/IP host may exist anywhere on the network, as long as the following two conditions are maintained:
This functionality is coordinated by your system administrator at the site where the TCP/IP host is located. You should not attempt to use AutoInstall unless the required files have been provided on the TCP/IP host. See the appropriate software configuration publications for information on how AutoInstall works.
Take the following steps to prepare your router for the AutoInstall process:
Hostname# copy running-config startup-config
If you do not plan to use AutoInstall, do not connect the router's serial (WAN) cable to the channel service unit/data service unit (CSU/DSU). This will prevent the router from attempting to run the AutoInstall process. The router will attempt to run AutoInstall whenever you start it if the serial (WAN) connection is connected on both ends and the router does not have a configuration stored in NVRAM. It can take several minutes for the router to determine that AutoInstall is not set up to a remote TCP/IP host.
Once the router has determined that AutoInstall is not configured, it will default to the setup facility. If the serial (WAN) cable is not connected, the router will boot from Flash memory and go into the setup facility.
When you first start the setup program, you must configure the global parameters. The global parameters are used for controlling system-wide settings. Use the following procedure to enter the global parameters:

The Cisco 7513 is now minimally configured and ready to use. Use the setup command if you want to modify the parameters after the initial configuration. To perform more complex configurations, use the configure command.
For information on additional interface configuration and information on more specific system configurations, refer to the section "If You Need More Configuration Information."
You can configure the Cisco 7513 manually if you prefer not to use the setup facility or AutoInstall. Take the following steps to configure the router manually:
Would you like to enter the initial dialog? [yes]: no
Router
>). Type enable to enter enable mode. Configuration changes can only be made in enable mode:
Router> enable

Router(config)#
prompt, enter the interface type slot/port command to enter the interface configuration mode:
Router(config)# interface serial slot/port Router(config-int)#
The Cisco 7513 is now minimally configured and will boot with the configuration you have entered. To see a list of the configuration commands available to you, enter ? at the prompt or press the help key while in configuration mode.
You can check the value of the settings you entered by entering the following commands at the # prompt: show running-config if you are running Cisco IOS Release 11.0 or later, or write terminal if you are running a Cisco IOS Release earlier than 11.0.
router# show running-config . . .
To store the configuration or changes to your startup configuration, enter the following commands at the hostname# prompt: copy running-config startup-config if you are running Cisco IOS Release 11.0 or later, or write memory if you are running a Cisco IOS release earlier than Release 11.0.
Hostname# copy running-config startup-config
Entering this command will save the configuration settings that you created in the router using configuration mode. If you fail to do this, your configuration will be lost the next time you reload the router.
To display information stored in NVRAM, use the show startup-config EXEC command if you are running Cisco IOS Release 11.0 or later, or the show config EXEC command if you are running a Cisco IOS release earlier than 11.0.
To make advanced configuration changes after you establish the basic startup configuration for your router, refer to the section "If You Need More Configuration Information" for the appropriate configuration publications; these publications contain additional information on using the configure command.
The configuration publications also provide information about the following tasks:
After you have installed the Cisco 7513 hardware, checked all external connections, turned on the system power, allowed the system to boot up, and minimally configured the system, you might need to perform more complete and complex configurations, which are beyond the scope of this text.
