This chapter briefly describes procedures for configuring the router, and contains the following sections:
This chapter provides minimum software configuration information; it is not intended as complete router configuration instructions. Detailed software configuration information is available in the Cisco IOS configuration guide and command reference publications. These publications are available on the documentation CD that accompanied your order or you can order printed copies.
Booting the Router for the First Time
Each time you power on the router, it goes through the following boot sequence:
The first time you boot your router, you will need to configure the router interfaces and then save the configuration to a file in NVRAM. See the section "Configuring the Router for the First Time" or refer to the configuration note for the appropriate module for interface configuration information. See the section "Saving Configuration Changes" later in this chapter for information on how to save the router configuration to NVRAM.
Because many privileged-level EXEC commands are used to set operating parameters, you should password-protect access to privileged mode to prevent unauthorized use.
You can set two passwords to do this:
The enable password and enable secret password must be different. 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.
For information about setting passwords, refer to the Cisco IOS configuration guides and command references. You can also set these passwords using the setup facility. See the section "Using the System Configuration Dialog" later in this chapter.
If you lose or forget your enable password, see the section "Recovering a Lost Enable Password" in the appendix "Troubleshooting." The enable secret password is encrypted, and cannot be recovered; you must replace it with a new enable secret password.
Configuring the Router for the First Time
You can configure the router using one of the following procedures, which are described in this section:
Proceed with the procedure that best fits the needs of your network configuration and Cisco IOS software experience level.
If you will be using configuration mode or AutoInstall to configure the router, and you would like a quick review of the Cisco IOS software, refer to the section "Cisco IOS Software Basics" later in this chapter.
Using the System Configuration Dialog
If you do not plan to use AutoInstall, make sure all the WAN cables are disconnected from the router. The router will attempt to run AutoInstall whenever you power it on if there is a WAN connection on both ends and the router does not have a configuration file stored in NVRAM. It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.
If your router does not have a configuration (setup) file and you are not using AutoInstall, the router will automatically start the setup command facility. An interactive dialog called the System Configuration Dialog appears on the console screen. This dialog helps you navigate through the configuration process by prompting you for the configuration information necessary for the router to operate.
Many prompts in the System Configuration Dialog include default answers, which are included in square brackets following the question. To accept a default answer, press Return; otherwise, enter your response.
This section gives an example configuration using the System Configuration Dialog. When you are configuring your router, respond as appropriate for your network.
At any time during the System Configuration Dialog, you can request help by typing a question mark (?) at a prompt.
Before proceeding with the System Configuration Dialog, obtain from your system administrator the node addresses and the number of bits in the subnet field (if applicable) of the router ports. For more information about IP addresses and subnets, refer to the Internetworking Technology Overview publication.
Take the following steps to configure the router using the System Configuration Dialog:
Configuring the ISDN BRI Interface
This section describes how to configure the ISDN BRI interface. If your router does not include an ISDN BRI interface, proceed to the next section, "Configuring Ethernet Interfaces."
The ISDN BRI interface is configured to allow connection to ISDN WANs. Determine which protocols to support on the ISDN BRI interface and enter the appropriate responses. In the following example, the system is being configured for IP, AppleTalk, and IPX:
Configuring Ethernet Interfaces
The Ethernet interfaces are configured to allow connection to a LAN. To configure the interface parameters, you need to know the Ethernet interface network addresses.
Take the following steps to configure an Ethernet interface to allow communication over a LAN:
Configuring Token Ring Interfaces
The Token Ring interfaces are configured to allow connection to a LAN. To configure the interface parameters, you need to know the Token Ring interface network addresses.
Take the following steps to configure a Token Ring interface to allow communication over a LAN:
The serial interfaces are configured to allow connection to WANs through a CSU/DSU. All serial ports are initially configured as synchronous ports. After the initial configuration is completed, configure the serial ports you plan to use as asynchronous ports using the physical-layer command in configuration mode.
Take the following steps to configure the serial port(s):
If you have asynchronous serial, T1, or E1 interfaces installed in your router, proceed to the section "Additional Startup Configuration Tasks."
Refer to the section "Cisco IOS Software Basics" for more information about the Cisco IOS software.
Additional Startup Configuration Tasks
When you have completed the setup facility, you might need to complete some additional configuration tasks. Complete the following tasks that apply to your installation:
Setting Asynchronous Serial Ports
The ports you plan to use as low-speed asynchronous serial ports must be reconfigured after the initial setup.
Take the following steps to configure a synchronous serial port to be an asynchronous serial port:
This completes the procedure to configure a synchronous serial interface for asynchronous operation.
Setting Synchronous Serial Ports
Use this procedure if it is necessary to set a serial port previously configured for asynchronous operation back to synchronous operation.
Take the following steps to configure a low-speed asynchronous serial port to be a low-speed synchronous serial port:
This completes the procedure to configure an asynchronous serial interface for synchronous operation.
Low-speed serial ports that are set as DCE can be set to use either controlled carrier mode or constant carrier mode.
Controlled carrier mode sets the interface to deactivate data carrier detect (DCD) until a transmission is sent to the interface. DCD is then activated, and the interface waits an amount of time you configure, and then transmits the data. After the transmission, the interface waits for a period of time and then deactivates DCD.
Constant carrier mode (the default for low-speed interfaces) activates DCD at all times.
Take the following steps to enable controlled carrier mode:
Table 4-2 : Half-Duplex Timer Commands
This completes the procedure to set half-duplex mode in a serial interface.
If your router includes a CT1/PRI (or CT1/PRI-CSU) module, you must enter configuration mode to configure the interfaces.
This procedure can also be used to change the configuration of an existing CT1/PRI module or to configure a CT1/PRI module newly installed in an existing system. If you replaced a CT1/PRI module that was previously configured, the system will recognize the new module and bring it up with the existing configuration.
Use the privileged-level configure command to configure the new module. Have the following information ready when you begin your configuration:
Take the following steps to complete a basic T1 configuration:
This completes the procedure to configure a CT1/PRI interface.
If your router includes a CE1/PRI module (balanced or unbalanced), you must enter configuration mode to configure the interface.
This procedure can also be used to change the configuration of an existing CE1/PRI module or to configure a CE1/PRI module newly installed in an existing system. If you replaced a CE1/PRI module that was previously configured, the system will recognize the new module and bring it up with the existing configuration.
When you have verified that the new CE1/PRI module is recognized by the router, use the privileged-level configure command to configure the new CE1/PRI module. Have the following information ready when you begin your configuration:
Take the following steps to complete a basic E1 configuration.
This completes the procedure to configure a CE1/PRI interface.
Configuring the Router Using Configuration Mode
When you install a new module or WAN interface card, or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the interfaces. If you replace a module or card that was already configured, the router recognizes it and brings up the interfaces in the existing configuration.
Before you configure an interface, have the following information available:
Take the following steps to configure the router manually:
To see the current operating configuration, including any changes you just made, enter the show running-config command at the privileged EXEC prompt:
To see the configuration currently stored in NVRAM, enter the show startup-config command at the privileged EXEC prompt.
The results of the show running-config and show startup-config commands differ from each other if you have made changes to the configuration and have not yet written them to NVRAM.
To write your changes to NVRAM, making them permanent, enter the copy running-config startup-config command at the privileged EXEC prompt:
The router is now configured to boot using the new configuration.
Configuring the Router Using AutoInstall
The AutoInstall process is designed to configure the router automatically after connection to your WAN. In order for AutoInstall to work properly, a TCP/IP host on your network must be configured to provide the required configuration files.
The TCP/IP host can reside anywhere on the network as long as the following two conditions are satisfied:
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 installed on the TCP/IP host.
Take the following steps to prepare your router for the AutoInstall process:
This section provides you with some basic information about the Cisco IOS software and includes the following sections:
Cisco IOS software provides access to several different command modes. Each command mode provides a different group of related commands.
For security purposes, Cisco IOS software provides two levels of access to commands: user and privileged. The unprivileged user mode is called user EXEC mode. The privileged mode is called privileged EXEC mode and requires a password. The commands available in user EXEC mode are a subset of the commands available in privileged EXEC mode.
Table 4-3 describes some of the most commonly used modes, how to enter the modes, and the resulting prompts. The prompt helps you identify which mode you are in and, therefore, which commands are available to you.
Almost every configuration command also has a no form. In general, use the no form to disable a feature or function. Use the command without the keyword no to reenable a disabled feature or to enable a feature that is disabled by default. For example, IP routing is enabled by default. To disable IP routing, enter the no ip routing command and enter ip routing to reenable it. The Cisco IOS software command reference publication provides the complete syntax for the configuration commands and describes what the no form of a command does.
Getting Context-Sensitive Help
In any command mode, you can get a list of available commands by entering a question mark (?).
To obtain a list of commands that begin with a particular character sequence, enter those characters followed immediately by the question mark (?). Do not include a space. This form of help is called word help, because it completes a word for you.
To list keywords or arguments, enter a question mark in place of a keyword or argument. Include a space before the question mark. This form of help is called command syntax help, because it reminds you which keywords or arguments are applicable based on the command, keywords, and arguments you have already entered.
You can also abbreviate commands and keywords by entering just enough characters to make the command unique from other commands. For example, you can abbreviate the show command to sh.
Any time you make changes to the router configuration, you must save the changes to memory because if you do not, they will be lost if there is a system reload or power outage. There are two types of configuration files: the running (currently operating) configuration and the startup configuration. The running configuration is stored in RAM; the startup configuration is stored in NVRAM.
To display the current running configuration, enter the show running-config command. Enter the copy running-config startup-config command to save the current running configuration to the startup configuration file in NVRAM.
To display the startup configuration, enter the show startup-config command. Enter the copy startup-config running-config command to write the startup configuration to the running configuration:
To erase both configuration files (and start over), enter the write erase and reload commands:
Checking and Saving Your Settings
To check the settings you have configured, enter the show running-config command at the enable (#) prompt:
To store the configuration, enter the copy running-config startup-config command at the enable (#) prompt:
This command saves the configuration settings that the setup process created. If you fail to do this, your new configuration will be lost the next time you reload the router.
When you have finished configuring the network interfaces, use the show interface command to check network interface statistics. Options to the show interface command include the following:
The following example shows the output of the show interface serial 0/0 command:
To display the current internal status of a module, use the show controller command with the interface number options. The following example shows the output of the show controller serial 0/1 command:
Note that in this example, the cable type is shown as no cable. If a cable is attached to the port, the cable type is shown, as in the following example:
If the cable is DCE, the output of the show controller command displays the clock rate. For complete command descriptions and instructions, refer to the Cisco IOS configuration guides and command references.
If you need more information, refer to the publications that shipped with the router:
