Configuring the AccessPro PC Card

Configuring the AccessPro PC Card

This chapter describes the procedures for configuring the AccessPro PC card and contains the following sections:

You should follow the configuration procedure that best fits the needs of your PC and network configuration.

Configuring the AccessPro card requires terminal emulation software. You can use Configuration Builder software to create the configuration file you will use with your AccessPro card. If you have an ASCII configuration file already prepared, you should install manually without using the setup routine.

Note You can boot and configure your AccessPro card from a Trivial File Transfer Protocol (TFTP) server that is attached to the same LAN as the AccessPro card. This process is referred to as netbooting. Follow the instructions in the section "Loading Software Images from a TFTP Server" in the chapter "Maintaining the AccessPro PC Card" to netboot your AccessPro card.

Configuring the AccessPro Card Using AutoInstall

The AutoInstall process is designed to configure the AccessPro card automatically after connection to a 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 to the AccessPro card. The TCP/IP host is typically a UNIX-based system. The TCP/IP host may exist anywhere on the network, as long as the following two conditions are maintained:


  1. The host is on the opposite side of the AccessPro card's serial connection to the WAN.

  2. User Datagram Protocol (UDP) broadcasts to and from the AccessPro card and the TCP/IP host are enabled.

This functionality is coordinated by your system adminstrator 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.

Before performing the AutoInstall process, power on the PC, start the terminal emulation software, and initiate a console session.

AutoInstall Process

Once you have initiated a console session, the AccessPro card 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. This process consists of the following operations:


  1. The AccessPro card sends a Serial Line Address Resolution Protocol (SLARP) packet over the serial line. When the packet reaches the opposite end of the WAN connection, the remote router replies with the Internet Protocol (IP) address of its serial interface. The AccessPro card increments the serial interface address by one and assigns this address to its own serial interface. This process takes approximately one minute.
Note The remote router's IP address must have a 1 as the fourth byte--for example, 127.100.21.1.

  1. After the serial interface on the AccessPro card is assigned a valid serial interface IP address, the AccessPro card resolves its host name. It sends a TFTP request on the serial line for the configuration file called network-confg. If the TCP/IP host responds with this file, AutoInstall searches the file's contents for the host name associated with its IP address.

  2. If the TCP/IP host does not respond with the network-confg file, AutoInstall broadcasts a reverse domain name server request containing the IP address for the AccessPro card's serial port that it was assigned over the network. If the domain name server services have been set up, AutoInstall resolves the AccessPro card's name from this file.

  3. After the IP address and host name have been found, AutoInstall broadcasts a TFTP request to the TCP/IP host for the file called hostname-confg. If this file has been set up by the system administrator, it is downloaded automatically to the AccessPro card's memory, completing the configuration.

Once the AutoInstall has completed successfully, you should copy the configuration data to the AccessPro card's NVRAM and reset the configuration registers. (See the following section, "Copying Configuration Data to NVRAM.")

If the AutoInstall process does not complete successfully, configure the AccessPro card using the setup routine, following the instructions in the section "Configuring the AccessPro Card Using the Setup Routine" later in this chapter.

Copying Configuration Data to NVRAM

To copy the configuration data to the AccessPro card's NVRAM and reset the configuration registers, perform the following steps:

Step 1 Enter the command enable at the EXEC prompt to enter privileged EXEC mode. Configuration changes can only be made in privileged EXEC mode.

Step 2 Enter the enable password that was configured into the AccessPro card by the AutoInstall process:

Step 3 Enter the command copy running-config startup-config at the Hostname# prompt:

Entering this command will save the configuration settings that the AutoInstall process created in the AccessPro card. If you fail to do this, your configuration will be lost the next time you reload the AccessPro card.


Note If you are using Cisco Internetwork Operating System (Cisco IOS) software earlier than Release 11.0, enter the command write memory to save the configuration settings created during the AutoInstall process.

Step 4 You can check the value of the configuration settings by entering the command show version at the Hostname# prompt:

If the AutoInstall feature is not set up, or if your AccessPro card is unable to locate the appropriate files, you should configure the AccessPro card using the setup routine or manually, without using the setup routine.

Configuring the AccessPro Card Using the Setup Routine

If you do not plan to use AutoInstall, disconnect the AccessPro card's serial (WAN) cable from the CSU/DSU and from the AccessPro card before using the setup routine. The AccessPro card will attempt to run AutoInstall whenever you start it if the serial (WAN) connection is connected and the AccessPro card does not have a configuration stored in NVRAM. Disconnecting this cable will prevent the AccessPro card from attempting to run the AutoInstall process.

Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.")

It can take several minutes for the AccessPro card to determine that AutoInstall is not set up on a remote TCP/IP host. Once the AccessPro card has determined that AutoInstall is not configured, it will default to the setup routine. If the serial (WAN) cable is not connected, the AccessPro card will boot from Flash memory and go into the setup routine.

Note You can run the setup routine any time you are at the privileged EXEC prompt (#) by entering the setup command.

Take the following steps to complete the setup routine:

Step 1 When you have booted from Flash memory, the following information will appear after about 30 seconds. When you see this information displayed, you have successfully booted your AccessPro card. Enter yes or press Return to enter the initial configuration dialog.

Step 2 To configure global parameters, choose what protocols to support on your Ethernet or Token Ring interface. For IP-only installations, you can accept the default values (in brackets) for most of the questions by pressing Return. A typical configuration follows; you will enter your own host name and passwords:

Step 3 If you are using Cisco IOS software earlier than Release 10.3(2), you will enter an enable password. If you are using Cisco IOS Release software 10.3(2) or later, you will enter an enable secret password.

Enable secret is an encrypted password which is used, when it exists, instead of the enable password.


Note Because it is encrypted, the enable secret password cannot be recovered using the procedure described in the section "Recovering a Lost Password" in the chapter "Maintaining the AccessPro PC Card." See the section "Configuring a New Enable Secret Password" in the chapter "Maintaining the AccessPro PC Card."

If you can enter an enable secret password, do as follows:


The enable password is used when there is no enable secret password, and when you are using older software and some boot images:


Note You will need to acquire the correct network addresses from your system administrator before you can complete the next two steps.

Step 4 To configure the interface parameters, you need to know your Ethernet or Token Ring interface and subnetwork addresses, as well as the address for your serial WAN and BRI interfaces. Respond as follows to the setup prompts:

Step 5 The PC bus is not used on the AccessPro card, so it is not configured. Enter no at the PC bus inquiry:

Step 6 Once you have configured the Ethernet or Token Ring interface on your AccessPro card, you need to configure the serial WAN interface:

Step 7 Once you have configured the serial WAN interface on your AccessPro card, you need to configure the BRI interface. Respond to the prompts as follows, substituting the correct IP address where appropriate:

Step 8 The configuration you have entered is now displayed and you are asked if you want to use it. If you answer no, you can begin the configuration again and make any changes you want. If you answer yes, this configuration will be entered and saved in the configuration database.

Your AccessPro card is now configured.

Checking Your Settings

You can check the value of the settings you have entered by entering the command show version at the Hostname> (EXEC mode) or the Hostname# (privileged EXEC mode) prompt:

acpro# show version . . . configuration register is 0x0 (will be 0x2102 at next reload)

Configuring the AccessPro Card without Using the Setup Routine

You can configure the AccessPro card manually if you prefer not to use the setup routine or AutoInstall.

Take the following steps to configure the AccessPro card manually:

Step 1 When you are asked if you would like to enter the initial configuration dialog, enter no to go into the normal operating mode of the AccessPro card:

Step 2 After a few seconds you will see the default prompt (Router>). Enter enable to enter enable mode. Configuration changes can only be made in enable mode:

The prompt will change to the enable mode prompt:


Step 3 Enter the config terminal command at the enable prompt to enter configuration mode:

You can now make any configuration changes required. Press Ctrl-Z to exit configuration mode.


To see the currently operating configuration, enter the command show running-config at the enable prompt:

acpro# show running-config
Note If you are using Cisco IOS software earlier than Release 11.0, enter the command write terminal to see the currently operating configuration.

To see the configuration in NVRAM, enter the command show startup-config at the enable prompt:

acpro# show startup-config
Note If you are using Cisco IOS software earlier than Release 11.0, enter the command show config to see the configuration in NVRAM.

The results of the commands show running-config and show startup-config will vary if you have made changes to the configuration in enable mode but have not yet written them to NVRAM.

Remember that to make your changes permanent you must enter the command copy running-config startup-config at the enable prompt:

acpro# copy running-config startup-config

Your AccessPro card is now configured and will boot with the configuration each time it or the PC is booted.

Configuring the ISDN Interface

After configuring the BRI interface, you must configure the AccessPro card to operate with ISDN. Typical ISDN configurations for a single B channel and for a dual B channel arrangement are described in this section.

Note The IP address and other information used in these examples should be replaced with IP addresses and information that is specific for your installation.

Configuring the ISDN Interface for a Single B Channel

To configure the AccessPro card for a basic ISDN point-to-point connection on a single B channel, take the following the steps, substituting the correct addresses and host names where appropriate:

Step 1 Enter the global configuration mode using the command config terminal at the privileged EXEC prompt:

Step 2 Enter the command username name password password to specify the host name and password for the router to which the ISDN connection is being made:

Note The username and password are the exact host name and password of the router to which the ISDN connection is to be made. Enter this information carefully because the username and password are case-sensitive.

Step 3 Enter the ISDN switch type using the command isdn switch-type. The switch type is typically National ISDN-1 (NI-1) or AT&T 5ESS depending on the equipment you have installed:

Step 4 Enter the BRI interface, the encapsulation method (Point-to-Point Protocol [PPP]), the PPP authentication method, the target router's host name and IP address, and the ISDN number to be dialed, followed by the dialer group:

Note Do not use periods or hyphens when you enter dialing numbers for ISDN interfaces.

Step 5 Enter the command ip route to configure a static route to allow connectivity to the target router's local network. Enter the network number for the target router's local IP network (160.10.1.0), the subnet mask (255.255.255.0), and the IP address of the target router's BRI interface:

Step 6 Enter the command access-list to configure a filter that causes the ISDN line to be brought up whenever any IP packets are to be sent:

Some ISDN switch types require that you configure a Service Profile Identifier (SPID). See the section "Configuring a Service Profile Identifier" later in this chapter.

Configuring the ISDN Interface for Two B Channels

To configure the AccessPro card for a basic ISDN point-to-point connection on two ISDN B channels, take the following steps, substituting the correct addresses and host names where appropriate:

Step 1 Enter the global configuration mode using the command config terminal at the privileged EXEC prompt:

Step 2 Enter the command username name password password to specify the host name and password for the router to which the ISDN connection is being made:

Note The username and password are the exact host name and password of the router to which the ISDN connection is to be made. Enter this information carefully because the username and password are case-sensitive.

Step 3 Enter the ISDN switch type using the command isdn switch-type. The switch type is typically National ISDN-1 (NI-1) or AT&T 5ESS depending on the equipment you have installed:

Step 4 Enter the BRI interface, the encapsulation method (PPP), the PPP authentication method, the target router's host name and IP address, and the ISDN number to be dialed, followed by the dialer group:

Note Do not use periods or hyphens when you enter dialing numbers for ISDN interfaces.

Step 5 Enter the command dialer load-threshold to set the load threshold for the ISDN interface. The load threshold determines the percentage of network loading at which the second ISDN B channel is triggered. The value ranges from 255 (100 percent) to 1:

In this 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 be activated to assist with the bandwidth load.


Step 6 Enter the command ip route to configure a static route to allow connectivity to the target router's local network. Enter the network number for the target router's local IP network (160.10.1.0), the subnet mask (255.255.255.0), and the IP address of the target router's BRI interface:

Step 7 Enter the command access-list to configure a filter that causes the ISDN line to be brought up whenever any IP packets are to be sent:

Configuring a Service Profile Identifier

Some ISDN switch types, such as Basic NI-1 or DMS-100, require that you configure a SPID. Enter the information as follows, substituting the SPIDs for your ISDN switch where appropriate:

The ISDN interface is now configured.

Using Windows NT with the AccessPro Card

During the boot process for Microsoft Windows NT, the PC COMports will receive a Break command as a result of Windows NT probing for a serial mouse. This Break command will cause the AccessPro card to break out of the system image and go to the ROM monitor (monitor prompt), interrupting operation of the AccessPro card.

Consult your Microsoft Windows NT documentation for instructions on how to disable this process for the COMport used by the AccessPro card.
