Overview

The WS-X3011 router card must have software release 11.28 installed to fully support the WS-X3011 card. Cards with software release 11.0(11) can support the WS-X3011 card; however, the card will be identified as a Cisco 2503 unit instead of as a WS-X3011card. For best results, upgrade to release 11.28 if your card is running a previous release. Your switch must be running software release 2.0(1) or higher.

Figure 1 shows the router card (WS-X3011).

The specifications of the router card are listed in Table 1.

Safety Recommendations

Follow these guidelines to ensure general safety:

• Keep the chassis area clear and dust-free during and after installation.

• Keep tools away from walk areas where you and others could fall over them.

• Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves.

• Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.

• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Warning  

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide for translations of the warnings in this document.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide.)

Maintaining Safety with Electricity

Follow these guidelines when working on equipment powered by electricity.

Warning  

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide.)

Warning  

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide.)

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide.)

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit. Always check.

Warning Read the installation instructions before you connect the system to its power source. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide.)

• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.

• If an electrical accident occurs, proceed as follows:

  • Use caution; do not become a victim yourself.

  • Turn OFF power to the system.

  • If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

  • Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic components are improperly handled and can result in complete or intermittent failures.

Always follow ESD-prevention procedures when removing and replacing components. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 to 10 megohms (Mohms).

Preparing to Connect to a Network

When setting up your switch with a router card, consider distance limitations and potential electromagnetic interference (EMI) as defined by the EIA.

Warning The auxiliary ports contain safety extra-low voltage (SELV) circuits. BRI circuits are treated like telephone-network voltage (TNV) circuits. Avoid connecting SELV circuits to TNV circuits. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide.)

Console Port

The switch has a DB-9 console port that automatically detects baud rate. The default is 9600 baud; other supported baud rates are 1200, 2400, 4800, 19200, 38400, and 57600. Refer to the Catalyst 3100 Installation and Configuration Guide for detailed pin assignments for the cables you can use on the console port

Console Pin Assignments

Table 4 and Table 5 and two figures (Figure 2 and Figure 3) detail pin-assignment information for the cables you can use on the console port of the switch.

Terminal Connection

For a terminal connection, use a null-modem cable or a straight cable (EIA-232) with a null modem adapter attached. Refer to the Catalyst 3100 Configuration and Installation Guide for the EIA-232 cable description.

Modem Connection

For a modem connection, use a standard modem (straight) cable.

ISDN Connections

Use a BRI cable (not included) to connect the router directly to an ISDN port. (See Table 2.)

Warning Network hazardous voltages are present in the BRI cable. If you detach the BRI cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the BRI port (RJ-45 connector), regardless of when power is turned OFF. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide.)

Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide.)

Table 2 lists the specifications for ISDN BRI cables. Refer to the section "ISDN BRI Port and Cable Pinouts" for pinouts.

Synchronous Serial Connections

Before you connect a device to the synchronous serial port (labeled "SERIAL"), you will need to know the following:

• The type of device, DTE or DCE, you are connecting to the synchronous serial interface.

• The type of connector, male or female, required to connect to the device.

• The signaling standard required by the device.

DTE or DCE

A device that communicates over a synchronous serial interface is either a DTE or DCE device. A DCE device provides a clock signal that paces the communications between the device and the router card. A DTE device does not provide a clock signal. DTE devices usually connect to DCE devices. The documentation that came with the device should indicate whether it is a DTE or DCE device. (Some devices have a jumper to select either mode.) If you cannot find the information in the documentation, refer to Table 3 to help you select the proper device type.

Speed and Distance Limitations

Serial signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the greater the distance. All serial signals are subject to distance limits, beyond which a signal degrades significantly or is completely lost.

Table 4 lists the maximum speeds and distances for EIA/TIA-232 signals. This signaling standard supports unbalanced circuits at signal speeds up to 64 kbps.

Balanced drivers allow EIA/TIA-449 signals to travel greater distances than the EIA/TIA-232 signals. Table 5 lists the maximum speeds and distances for EIA/TIA-449, V.35, X.21, and EIA-530 signals.

Caution The EIA/TIA-449 and V.35 interfaces support data rates up to 2.048 Mbps. Exceeding this maximum could result in loss of data and is not recommended.

Signaling Standards

The synchronous serial port supports the following signaling standards: EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can order a DB-60 shielded serial transition cable that has the appropriate connector for the standard you specify. The router end of the shielded serial transition cable has a DB-60 connector, which connects to the serial port on the router card. The other end of the serial transition cable is available with the connector appropriate for the standard you specify. The documentation for the device you want to connect should indicate the standard used for that device. The synchronous serial port can be configured as DTE or DCE (except EIA-530, which is DTE only), depending on the attached cable.

Figure 2 shows the serial transition cables you can connect to the serial port on the router card.

Cisco does not recommend that you attempt to manufacture your own serial cables (because of the small size of the pins on the DB-60 serial connector). To order a cable, refer to the section "Obtaining Service and Support" at the end of this document. To manufacture your own cable, refer to the cable pinouts provided in the section "Cable, Pinout, and Port Specifications."

EIA/TIA-232 Connections

The EIA/TIA-232 standard supports unbalanced circuits at signal speeds up to 64 kbps. The serial port (labeled "SERIAL") supports synchronous connections. The console and auxiliary ports also use an EIA/TIA-232 connection; however, the console and auxiliary ports support asynchronous connections.

The network end of the EIA/TIA-232 serial transition cable (not included) provides a DB-25 connector, as shown in Figure 3. The end that connects to the serial port on the rear panel of the router has a DB-60 connector. EIA/TIA-232 serial transition cables are available with a DB-25 plug or receptacle in either DTE or DCE mode. To order a cable, refer to the section "Obtaining Service and Support."

EIA/TIA-449 Connections

The EIA/TIA-449 standard, which supports balanced and unbalanced transmissions, is a faster (up to 2 Mbps faster) version of the EIA/TIA-232 standard and provides more functions and supports transmissions over greater distances.

The network end of the EIA/TIA-449 serial transition cable (not included) provides a DB-37 connector, as shown in Figure 4. The end that connects to the serial port on the router card has a DB-60 connector. EIA/TIA-449 serial transition cables are available with a DB-37 plug or receptacle in either DTE or DCE mode. To order a cable, refer to the section "Obtaining Service and Support" at the end of this document.

V.35 Connections

The V.35 standard is recommended for speeds up to 48 kbps, although in practice it is used successfully at 4 Mbps.

The network end of the V.35 serial transition cable (not included) provides a standard 34-pin Winchester-type connector, as shown in Figure 5. The end that connects to the serial port on the router card has a DB-60 connector. V.35 cables are available with a standard V.35 plug or receptacle in either DTE or DCE mode. To order a cable, refer to the section "Obtaining Service and Support" at the end of this document.

X.21 Connections

The X.21 connector uses a 15-pin connector for balanced circuits and is commonly used in the United Kingdom to connect to the public data network. X.21 relocates some of the logic functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232.

The network end of the X.21 serial transition cable (not included) is a standard DB-15 connector, as shown in Figure 6. The end that connects to the serial port on the router card has a DB-60 connector. X.21 cables are available with a plug or receptacle in either DTE or DCE mode. To order a cable, refer to the section "Obtaining Service and Support" at the end of this document.

EIA-530 Connections

The EIA-530 standard, which supports balanced transmission, provides the increased functionality, speed, and distance of EIA/TIA-449 on the smaller, DB-25 connector used for EIA/TIA-232, instead of the 37-pin connector used for EIA/TIA-449. Like EIA/TIA-449, EIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423. Although the specification recommends a maximum speed of 2 Mbps, EIA-530 is used successfully at 4 Mbps or faster speeds over short distances.

The EIA-530 serial transition cable (not included) is available in DTE mode only. The network end of the EIA-530 adapter cable is a standard DB-25 plug commonly used for EIA/TIA-232 connections, as shown in Figure 7. The end that connects to the serial port on the router card has a DB-60 connector. To order a cable, refer to the section "Obtaining Service and Support" at the end of this document.

Installing the Router Card

This section guides you through the installation of the router card and includes the following subsections:

• Required Tools and Equipment

• Connecting the Console Terminal

• Connecting to a Network

The Cisco configuration guide and command reference publications provide additional software configuration information. These publications are available in the CD ROM package that came with your switch, or you can order printed copies. Refer to the section "Ordering Documentation" at the end of this document.

Warning Only trained and qualified personnel should be allowed to install or replace this equipment. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3100 Configuration and Installation Guide.)

Required Tools and Equipment

Installation requires some tools and equipment that are not provided as standard equipment with the router card. Following are the tools and parts required to install the router card:

• CSU/DSU or other DCE device for connection to the synchronous serial interface.

• NT1 device for ISDN BRI WAN connections, if not supplied by your service provider.

Connecting the Console

You must have a console connected to the switch to configure the router card after it is installed. If a console is connected to the switch already, proceed to the next section; otherwise, perform the following steps to connect a console to the switch:

Step 1 Connect the switch to a PC or other DTE (Data Terminal Equipment) device using a straight, 25-pin to 9-pin EIA (RS)-232 cable and a null modem adapter. Refer to the section "Preparing to Connect to a Network" in this document for a description of the cables and adapters.

Step 2 Connect the EIA-232 cable to the DB-9 connector (console) on the switch. The male DB-9 connector on the switch is configured as a DTE device.

Step 3 Use Table 6 to set the configuration parameters on the console for communication with the switch.

At power on (cold boot), the switch performs a series of self-test diagnostics that verify that hardware components are functioning. The diagnostic self-test for the switch displays two different screens (lists of information), depending on whether you perform a cold boot (power on cycle with full diagnostics), or a warm boot (a reset without full diagnostics). For detailed information about these diagnostics, refer to the Catalyst 3X00 Installation and Configuration Guide.

At the end of the boot messages, you should be prompted to press RETURN. The Greeting screen of the switch Console Manager should appear, as shown in Figure 8.

If the diagnostic list does not appear, or the list is garbled, refer to the "Encountering Communication Problems" section in this document..

Step 5 At the Greeting screen, press RETURN to enter the Main menu. The contents of the Main menu, instructions for setting a Password and all information within the menus and sub-menus are described in the Catalyst 3X00 Installation and Configuration Guide.

Encountering Communication Problems

To adjust the baud rates between the console and the switch if the diagnostic list does not appear or the list is garbled, use the Autobaud routine within the switch. Press the Reset button on the switch and wait for the internal diagnosis to finish (the Diagnostic LED goes off). Resetting the switch resets the Autobaud routine to its default mode of enabled.

The console command keys that initiate the Autobaud routine depend on the type of console. Four of the command keys are RETURN, the combination keys ALT-B, the BREAK key, or ESCAPE.

After the DIAG LED goes out, at the console press one of the command keys repeatedly. If there is no response, wait several seconds and again press it repeatedly. If there is still no response, perform the same routine using the other command keys.

If none of the command keys work but there is garbled output on the screen, push the SysReq button on the switch. As soon as garbled characters appear, press the console's RETURN key twice in rapid succession. (Again, try the other command keys as necessary.)

If there is still a problem, perform the following steps:

Step 1 Check all of the cable connections.

Step 2 Check the baud rate at the console's setup screen; make sure the baud rate is set to the default, 9600.

Step 3 Set the console baud rate to different values up or down, pressing RETURN after each selection.

Step 4 If you are using a terminal emulation program, try exiting the program and restarting.

Step 5 If you still can not get the connection to work, contact a support person.

Connecting to a Network

This section explains how to connect the router card to your network. The synchronous serial and ISDN ports are used to connect the router to a WAN.

The cables required to connect the router card to a network are not provided with the card. For ordering information, refer to the section "Obtaining Service and Support" in this document. For cable pinouts, refer to the section "Cable, Pinout, and Port Specifications" in this document.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.(To see translated versions of this warning, refer to the appendix "Translated Safety Warnings" in the Catalyst 3X00 Configuration and Installation Guide.)

Take the following steps to connect your router card to a network:

Step 1 If you will be using AutoInstall to configure the router card, connect the synchronous serial port (DB-60) to a CSU/DSU or other DCE device, as shown in Figure 9. If you do not plan to use AutoInstall (or you are not sure what AutoInstall is) do not connect the WAN cable until after you have configured the router card.

If a WAN cable is connected when you power ON the switch with the router card for the first time, it will attempt to run AutoInstall to download a configuration file from a TFTP server. It can take several minutes for the router card to determine that the necessary files are not in place for AutoInstall to begin. For more information about AutoInstall, refer to the Cisco IOS configuration guide, which is available in the CD ROM package that came with your switch.

Step 2 Connect the ISDN BRI port (RJ-45) to an NT1 device. (See Figure 10.)

Configuring the Router Card

This section describes how to configure the router card and contains the following topics:

• Booting the Switch with the Router Card for the First Time

• Configuring the Router Card for the First Time

• Cisco IOS Software Basics

• Configuring ISDN

• Verifying Network Connectivity

• Getting More Information

This section provides minimum software configuration information. Detailed software configuration information is available in the Cisco IOS configuration guide and command reference publications. These publications are available in the CD ROM package or you can order printed copies. Refer to the section "Ordering Documentation" at the end of this document.

Access the Router Card Command-Line Interface

To access the router card commad-line interface (CLI), perform the following steps:

Step 1 Connect a console terminal to the console port on your switch. (For more information, refer to the "Connecting the Console" section in this document.)

---

Note The default parameters for the internal console port on the router card are 9600 baud, 8 data bits, no parity, and 1 stop bit. This default baud rate matches the switch console baud rate. Do not change the default baud rate. If it has been changed, press Ctrl-B to toggle through the available baud rates to restore the default.

Although the router card CLI is based on the Cisco IOS CLI, pressing Ctrl-B does not function as a backspace key as it normally does in the Cisco IOS CLI; instead, it is used to change the console baud rate.

---

Step 2 Power ON the switch. The switch Greeting screen appears (Figure 8).

Step 3 Access the router card CLI by pressing Ctrl-R from the switch Main menu.

---

Note You can toggle back and forth between the two CLIs by pressing Ctrl-R.

Refer to the 'Getting Started' Guide for additional help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets '[]'. Would you like to enter the initial configuration dialog? [yes]:

Booting the Switch with the Router Card for the First Time

Each time you power on the switch, the router card performs the following boot sequence:

1. The router card performs power-on self-test diagnostics to verify basic operation of the CPU, memory, and interfaces.

2. The system bootstrap software (boot image) executes and searches for a valid Cisco IOS image (router operating system software). The source of the Cisco IOS image (Flash memory or a Trivial File Transfer Protocol [TFTP] server) is determined by the configuration register setting. The factory-default setting for the configuration register is 0x2102, which indicates that the router card should attempt to load a Cisco IOS image from Flash memory.

3. If after five attempts a valid Cisco IOS image is not found in Flash memory, the router card reverts to boot ROM mode (which is used to install or upgrade a Cisco IOS image).

4. If a valid Cisco IOS image is found, then the router card searches for a valid configuration file.

5. If a valid configuration file is not found in NVRAM, the router card runs the System Configuration Dialog so you can configure the card manually. For normal operation, there must be a valid Cisco IOS image in Flash memory and a configuration file in NVRAM.

The first time you boot your switch with the router card, you need to configure the router interfaces and then save the configuration to a file in NVRAM.

Configuring the Router Card for the First Time

You can configure the router card using one of the following procedures. Each procedure is described in detail later in this section:

• Using the System Configuration Dialog---Recommended if you are not familiar with Cisco IOS commands.

• Configuration mode---Recommended if you are familiar with Cisco IOS commands.

• AutoInstall---Recommended for automatic installation if a router running Cisco IOS software is installed on the network. This configuration method must be set up by someone with experience using Cisco IOS software.

TimeSaver Before you begin to configure the router card, obtain the correct network addresses from your system administrator or consult your network plan to determine the correct addresses.

Use 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 card, and you would like a quick review of the Cisco IOS software, refer to the section "Cisco IOS Software Basics" later in this chapter. Otherwise, proceed with the next section, "Using the System Configuration Dialog."

Using the System Configuration Dialog

If you do not plan to use AutoInstall, make sure all the WAN cables are disconnected from the router card. This will prevent the router card from attempting to run the AutoInstall process. The router card will attempt to run AutoInstall whenever you power it ON, if there is a WAN connection on both ends and the router card does not have a configuration file stored in NVRAM. The router card can take several minutes to determine that AutoInstall is not connected to a remote TCP/IP host.

If your router card does not have a configuration (setup) file and you are not using AutoInstall, the router card 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, prompting you for the configuration information necessary for the router card to operate.

Many prompts in the System Configuration Dialog include default answers, which are included in square brackets following the displayed 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 card, 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 you begin to configure the router card, obtain the correct addresses and the number of bits in the subnet field (if applicable) of the router ports from you system administrator.

Take the following steps to configure the router card using the System Configuration Dialog:

Step 1 When you are prompted to enter the initial dialog, enter yes or press Return to enter the initial dialog mode:

Would you like to enter the initial dialog? [yes]: yes

Step 2 When the System Configuration Dialog asks whether you want to view the current interface summary, press Return or enter yes:

First, would you like to see the current interface summary? [yes]: Any interface listed with OK? value "NO" does not have a valid configuration InterfaceIP-AddressOK?MethodStatusProtocol Ethernet0unassignedNOnot setupdown BRI0unassignedNOnot setupup Serial0unassignedNOnot setdowndown Serial1unassignedNOnot setdowndown

Step 3 Configure the global parameters. A typical configuration follows:

Configuring global parameters: Enter host name [Router]:

Next, you are prompted to enter an enable secret password. There are two types of privileged-level passwords:

• Enable secret password (a very secure, encrypted password)

• Enable password (a less secure, nonencrypted password)

The enable password is used when the enable secret password does not exist.

For maximum security, be sure the passwords are different. If you enter the same password for both, the router card will accept your entry, but will display a warning message indicating that you should enter a different password.

Step 4 Enter an enable secret password:

The enable secret is a one-way cryptographic secret used instead of the enable password when it exists. Enter enable secret: pail The enable password is used when there is no enable secret and when using older software and some boot images.

Step 5 Enter the enable and virtual terminal passwords:

Enter enable password: shovel Enter virtual terminal password: vterm1

Step 6 Press Return to accept Simple Network Management Protocol (SNMP) management, or enter no to refuse it:

Configure SNMP Network Management? [yes]: no

Step 7 In the following example, the router card is configured for AppleTalk, Internet Protocol (IP), and Internetwork Packet Exchange (IPX). Configure the appropriate protocols for your router card:

Configure Vines? [no]: Configure LAT? [no]: Configure AppleTalk? [no]: yes Multizone networks? [no]: yes Configure DECnet? [no]: Configure IP? [yes]: Configure IGRP routing? [yes]: Your IGRP autonomous system number [1]: 15 Configure CLNS? [no]: Configure bridging? [no]: Configure IPX? [no]: yes Configure XNS? [no]: Configure Apollo? [no]:

Step 8 Enter the ISDN BRI switch type. The switch type appropriate for the router depends on the ISDN service provider's equipment. Table 7 lists the ISDN switch types.

Enter ISDN BRI Switch Type [none]: basic-5ess

Configuring the ISDN BRI Interface

After you have completed the entire initial router card interface configuration using the System Configuration Dialog, proceed to the section "Configuring ISDN" later in this document for additional ISDN configuration information.

Configuring the Ethernet Interface

Step 1 Press Return or enter yes to configure the LAN interface:

Step 2 Determine which protocols you want to support on the LAN interface and enter the appropriate responses. In the following example, the system is configured for IP, AppleTalk, and IPX:

Proceed to the section "Cisco IOS Software Basics" for more information about the Cisco IOS software.

Using Configuration Mode

You can configure the router card manually if you do not want to use AutoInstall or the prompt-driven System Configuration Dialog. Perform the following steps to configure the router card manually:

Step 1 When you are prompted to enter the initial dialog, enter no to enter the normal operating mode of the router card:

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

Step 2 After a few seconds you will see the user EXEC prompt (Router>). Enter the enable command to enter privileged EXEC mode. You can only make configuration changes in privileged EXEC mode:

Step 3 Enter the configure terminal command at the privileged EXEC prompt to enter configuration mode:

Refer to the Cisco IOS configuration guide and command reference publications for more information about the commands you can use to configure the router card. These manuals are available on CD ROM and in printed form. Refer to the section "Ordering Documentation" at the end of this document for information about how to obtain these documents.

Step 4 When you are finished configuring the router card, enter the exit command until you return to the privileged EXEC prompt (Router#).

Step 5 To save the configuration changes to NVRAM, enter the copy running-config startup-config command at the privileged EXEC prompt.

Using AutoInstall

The AutoInstall process is designed to configure the router card automatically after connection to your WAN. In order 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. For more information, refer to the Cisco IOS configuration guide and command reference publications. These manuals are available on CD ROM and in printed form. Refer to the section "Ordering Documentation" at the end of this document for information about how to obtain these documents.

After powering on the switch, the router interface loads the operating system image from Flash memory. If the remote end of the WAN connection is connected and properly configured, the AutoInstall process begins automatically.

After AutoInstall completes successfully, enter the copy running-config startup-config command in privileged EXEC mode to write the configuration data to the router card's NVRAM:

Router Card Configuration

Some parameters are configurable from the switch Main Menu. These parameters govern the bootup process, router reset, and router flow control and provide access to the router command line interface. To configure these parameters follow these steps:

Step 1 From the switch Main Menu, select Configuration>Router Configuration. The Router Configuration menu appears, as shown in Figure 11.

Step 2 At the Enter a port in box, port format (e.g. 2,15) prompt, enter the number of the Catalyst box containing the router card and the number of the port.

Cisco IOS Software Basics

This section provides you with some basic information about the Cisco IOS software, and includes the following topics:

• Cisco IOS Modes of Operation

• Getting Context-Sensitive Help

• Saving Configuration Changes

Cisco IOS Modes of Operation

The Cisco IOS software provides access to several different command modes. Each command mode provides a different group of related commands.

For security purposes, the 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 8 describes some of the most commonly used modes, how to enter the modes, and the resulting prompts. Each 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. 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. This manual is available on CD ROM and in printed form. Refer to the section "Ordering Documentation" at the end of this document for information about how to obtain these documents.

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, type in 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.

Saving Configuration Changes

Any time you make changes to the router configuration, you must save the changes to memory. If you do not, they will be lost in the event of a system reload or power outage. There are two types of configuration files: the running (current 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.

Caution This command sequence will erase the entire router configuration in RAM and NVRAM and reload the router.

Configuring ISDN

This section describes a typical ISDN configuration for one or two B channels. In the examples that follow, the BRI port is configured for IP routing, Challenge Handshake Authentication Protocol (CHAP), and Point-to-Point Protocol (PPP) encapsulation.

For your reference, an example configuration follows in the next section, "Example ISDN Configuration." You may want to refer to it during this procedure.

Take the following steps to configure the router for a basic ISDN PPP connection on a single B channel or two B channels, substituting the correct addresses and host names as appropriate for your network:

Step 1 Enter privileged EXEC mode:

Router> enable password: enablepassword

Step 2 Enter the configure terminal command to enter global configuration mode. Then enter the host name of the current router, the user name of the target router (the router to which packets will be sent), and the password that the routers will use for CHAP caller identification. The user name and password are case sensitive and must match the host name and password of the target router (even if it is not a Cisco router):

Router# configure terminal Router (config)# hostname currentrouter Router (config)# username targetrouter password abc

Step 3 Enter the isdn switch-type command to configure the ISDN switch type (such as basic-5ess, basic-dms100, or basic-ni1). Refer to Table 7, earlier in this chapter, for a list of ISDN switch types supported.

Router (config)# isdn switch-type switch-type

Step 4 Configure the IP address and subnet mask for the LAN interface:

Router (config)# interface type port_number Router (config-if)# ip address ipaddress subnetmask

Step 5 Configure the IP address and subnet mask for the BRI interface:

Router (config-if)# interface bri port_number Router (config-if)# ip address ipaddress subnetmask

Step 6 If you are using an ISDN switch type (such as Basic NI1 or DMS-100) that requires a service profile identifier (SPID), enter the SPID and optional local directory number (LDN). The SPID and LDN are assigned by the ISDN service provider.

The SPID is a number that identifies the service to which you have subscribed. A SPID is not required for AT&T 5ESS service configured for a point-to-point connection.

The LDN is an optional seven-digit phone number for the channel.

Router (config-if)# isdn spid1 SPID_no [LDN] Router (config-if)# isdn spid2 SPID_no [LDN]

Step 7 Configure the router for PPP encapsulation and CHAP authentication:

Router (config-if)# encapsulation ppp Router (config-if)# ppp authentication chap

Step 8 Enter the load-threshold or ppp multilink command to set up a second B channel.

For bandwidth on demand, enter the load-threshold command to set the ISDN load threshold. The load threshold determines the percentage of network load at which the second ISDN B channel is activated. The value ranges from 1 to 255 (100 percent). In the following example, the value of 128 means that when the first B channel reaches 50 percent of its bandwidth capacity (128 equals 50 percent of 255), the second B channel will activate to assist with the bandwidth load:

Router (config-if)# dialer load-threshold 128

Alternatively, you can use Multilink PPP to activate a second ISDN line. For Multilink PPP to work, the router must be running Cisco IOS Release 11.0(3) or a later release, and both the current router and target router must support Multilink PPP:

Router (config-if)# ppp multilink

Step 9 Enter the dialer map command to provide the information necessary to successfully route packets to the target router. Do not use periods or hyphens when entering the number to dial:

Router (config-if)# dialer map protocol targetBRIport_ipaddress name targetrouter_number

Step 10 Enter the dialer-group command to specify the number of the group permitted to access the router:

Router (config-if)# dialer-group groupnumber

Step 11 Enter the exit command to exit interface configuration mode.

Step 12 Enter the dialer list command to specify the groups and protocols permitted to access the router:

Router (config)# dialer-list groupnumber protocol protocol_type permit

Step 13 Configure a static route to allow connection to the target router's LAN. Enter the IP address and subnet mask of the target router's LAN interface, and the IP address of the target router's BRI port:

Router (config)# ip route targetrouter_ipnetwork subnetmask targetBRIport_ipaddress

Step 14 Enter the exit command to exit global configuration mode.

Step 15 Enter the copy running-config startup-config command to save the configuration to NVRAM.

Example ISDN Configuration

For your reference, Table 9 shows an example configuration for a Catalyst 3100 switch with a router card installed, and a Cisco router using IP over ISDN. In the example, the router card (branch1) is at a remote site and the target router (main1) is at a central site.

Verifying Network Connectivity

After you have installed and configured the router, you can use the following commands in user EXEC mode to verify network connectivity:

• telnet---Logs in to a remote node

• ping---Sends a special datagram to the destination device, then waits for a reply datagram from that device

• trace---Discovers the routes that packets take when traveling from one router to another

If there is a problem with network connectivity, refer to the section "Reading the LEDs" later in this document. If there is still a problem, check the switch configuration. Refer to the Catalyst 3X00 Installation and Configuration Guide.

Getting More Information

For more information about router software configuration, refer to the Cisco IOS configuration guide and command reference publications. These publications are available in the CD ROM that accompanied your switch, or you can order printed copies. Refer to the section "Ordering Documentation" at the end of this document.

Reading the LEDs

The LEDs indicate the current operating condition of the router card. You can observe the LEDs, note any fault condition that the router card is encountering, and then contact your system administrator or customer service, if necessary. For information about how to contact customer service, refer to the section "Obtaining Service and Support."

Figure 12 shows the location of the LEDs on the router card. The LEDs are labeled and indicate activity on a port by flickering. When there is heavy activity on a port, the LED might be ON constantly. If an LED is not ON when the port is active and the cable is connected correctly, there might be a problem with the port.
