Performing a Basic Configuration of the Cisco  7204

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly; therefore, it might be more up to date than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription.

There are two commands you can use to set the password protection:

• enable secret password (which is a very secure, encrypted password).

• enable password (which is a less secure, or nonencrypted, password).

You must enter the correct password to gain access to privileged-level commands. 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.

Before continuing the configuration process, check the current state of the router by entering the show version command. The show version command displays the release of Cisco IOS software that is available on the router.

1. The host must be on the remote side of the router's synchronous serial connection to the WAN.

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

This functionality is coordinated by your system administrator at the site where the TCP/IP host is located. You should not use AutoInstall unless the required files are available on the TCP/IP host. See the publications Configuration Fundamentals Configuration Guide and Configuration Fundamentals Command Reference for detailed information about how AutoInstall works.

Complete the following steps to prepare your Cisco  7204 for the AutoInstall process:

Step 1 Attach the appropriate synchronous serial cable to synchronous serial interface  0 on the router.

Step 2 Turn the power switch on each power supply to the ON (|) position. (This action turns on AC power to the router.)

The router 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.

Step 3 At the # prompt enter the following command:

Hostname# copy running-config startup-config

---

Note Completing this step saves the configuration settings that the AutoInstall process created to NVRAM. If you fail to do this, your configuration will be lost the next time you reload the router.

---

Once the router determines 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 automatically into the setup facility.

Step 1 Connect a console terminal to the console port on the I/O controller, and then boot the router.

The system boots from Flash memory. The following information appears after about 30 seconds. When you see this information, you have successfully booted your router:

---

Note The first two sections of the configuration script (the banner and the installed hardware) appear only at initial system startup. On subsequent uses of the setup command facility, the script begins with a System Configuration Dialog as shown in the following example.

---

Step 2 When asked if you want to enter the initial configuration dialog and see the current interface summary, enter yes or press Return:

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

First, would you like to see the current interface summary? [yes]:

In the following example, the summary shows a Cisco  7204 at first-time startup; that is, nothing is configured.

Step 4 Enter the enable secret password and the enable password:

The enable secret password is a one-way cryptographic secret
password used instead of the enable password when it exists.

Enter enable secret: barney

The enable password is used when there is no enable secret
password and when using older software and some boot images.

Enter enable password: betty

Enter yes to accept SNMP management; enter no to refuse it:

   Configure SNMP Network Management? [yes]:
Community string [public]:

Step 6 For the following query, do not enable CLNS:

Configure CLNS? [no]:

Configure AppleTalk? [no]: yes
Multizone networks? [no]: yes

Configure IPX? [no]: yes

Step 8 For the following queries, do not enable Vines, XNS, DECnet, or bridging:

Configure Vines? [no]:
Configure XNS? [no]:
Configure DECnet? [no]:
Configure bridging? [no]:

To configure IP routing, enter yes (the default) or press Return, and then select an interior routing protocol:

Configure IP? [yes]:
Configure IGRP routing? [yes]:
Your IGRP autonomous system number [1]: 15

Configure AppleTalk? [no]: yes
Multizone networks? [no]: yes

Configure IPX? [no]: yes

Step 1 In the following example, the system is being configured for an Ethernet LAN using IP. Respond to the prompts as follows, using your own addresses and mask at the setup prompts:

Step 2 Determine if you are going to enable IPX on this interface; if you are, enter the unique IPX network number:

Configure IPX on this interface? [no]: yes
IPX network number [2]:

Step 3 If you will be using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk networks, and then enter the cable range number. Enter the zone name and any other additional zones that will be associated with your local zone:

   Configure AppleTalk on this interface? [no]: yes
       Extended AppleTalk network? [no]: yes
       AppleTalk starting cable range [0]:

Step 1 To configure serial port 0 enter yes:

Configuring interface Serial1/0:
   Is this interface in use? [no]: yes

Configure IP unnumbered on this interface? [no]:
   IP address for this interface: 1.1.1.20
   Number of bits in subnet field [0]:
   Class A network is 1.0.0.0, 0 subnet bits; mask is 255.0.0.0

Configure IPX on this interface? [no]: yes
   IPX network number [2]:

Configure AppleTalk on this interface? [no]: yes
   Extended AppleTalk network? [no]:
   AppleTalk network number [1]:

Step 1 Connect a console terminal to the console port on the I/O controller.

Step 2 When asked if you want to enter the initial dialog, answer no to go into the normal operating mode of the router:

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

Router> enable

The prompt changes to the privileged EXEC prompt:

Router#

Router# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

At the Router(config)# prompt, enter the interface type slot/port command to enter interface configuration mode:

Router(config)# interface serial slot/port
Router(config-int)#

In either configuration mode, you can now enter any changes to the configuration. Press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode and return to the EXEC command interpreter.

Hostname# copy running-config startup-config

Using this command saves the configuration settings that you created in the Cisco  7204 using configuration mode and the setup facility. If you fail to do this, your configuration will be lost the next time you reload the router.

Router# show running-config
