First-Time Configuration

This chapter describes how to use the setup command facility to configure your router. The setup command facility prompts you to enter information needed to start a router functioning quickly. The facility steps you through a basic configuration, including local-area network (LAN) and wide-area network (WAN) interfaces. The following sections are included:

If you prefer to configure the router manually or you wish to configure a module or interface that is not included in the setup command facility, proceed to Chapter 2, "Cisco IOS Software Basics" to familiarize yourself with the command-line interface (CLI) and then proceed to Chapter 3, "Configuring with the Command-Line Interface" for step-by-step instructions.

Before You Begin

This section contains information with which you should be familiar before you begin to configure your router for the first time, including interface numbering and what you should do before starting your router.

Cisco 3600 Series Interfac e Number ing

Each individual network interface on a Cisco 3600 series router is identified by a slot number and a unit number.

Slot Numbering

A Cisco 3600 series router chassis includes up to six slots in which you can install modules. The Cisco 3600 series includes the Cisco 3660 (see Figure 1-1), Cisco 3640 (see Figure 1-2) and Cisco 3620 routers (see Figure 1-3). The Cisco 3660 has six network module slots, the Cisco 3640 has four slots, and the Cisco 3620 has two slots. You can install any module into any available slot in the chassis.

Figure 1-1: Cisco 3660 Router Rear View

Figure 1-2: Cisco 3640 Router Rear View

Figure 1-3: Cis co 3620 Router Rear View

For the Cisco 3660 router (see Figure 1-1), the slots are numbered as follows:

Slot 0 contains fixed Fast Ethernet ports and is located at the top of the chassis.
Slot 1 is at the bottom right (as viewed from the rear of the chassis), near the power supply.
Slot 2 is at the bottom left.
Slot 3 is at the right, above slot 1.
Slot 4 is at the left, above slot 2
Slot 5 is at the right, above slot 3.
Slot 6 is at the left, above slot 4.

For the Cisco 3620 and Cisco 3640 routers shown in Figure 1-2 and Figure 1-3, the slots are numbered as follows:

Slot 0 is at the bottom right (as viewed from the rear of the chassis), near the power supply.
Slot 1 is at the bottom left.
Slot 2 is at the top right, above slot 0.
Slot 3 is at the top left, above slot 1.

Some modules have two small slots, labeled W0 and W1, for WAN interface cards. For example, Figure 1-4 shows the W0 and W1 slots of the 2 Ethernet 2 WAN card slot
(2E 2-slot) module. You can install WAN interface cards into the small module slots (W0 and W1). Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) WAN interface cards are keyed so that you can install them into slot W1 only. Serial WAN interface cards can be installed into either slot, W0 or W1.

Figure 1-4: WAN Interface Card S lots

Unit Numbering

Cisco 3600 series routers unit numbers identify the interfaces on the modules and WAN interface cards installed in the router. Unit numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top. Modules and WAN interface cards are identified by interface type, slot number, followed by a forward slash
(/), and then the unit number; for example, Ethernet 0/0.

Note In the Cisco 3660 router, the fixed Fast Ethernet ports are located in chassis slot 0, and are identified by:

interface type chassis slot/ unit number

For example: Fast Ethernet 0/0

Figure 1-5 shows a router with a 2E 2-slot module in slots 0 and 1. Two serial WAN interface cards are installed in the module in slot 0. One serial and one ISDN BRI WAN interface card are installed in the module in slot 1.

As shown in Figure 1-5, the unit numbers are as follows:

Slot 0, Ethernet interface 0, referred to as Ethernet 0/0
Slot 0, Ethernet interface 1, referred to as Ethernet 0/1
Slot 0, serial interface 0, referred to as serial 0/0
Slot 0, serial interface 1, referred to as serial 0/1
Slot 1, Ethernet interface 0, referred to as Ethernet 1/0
Slot 1, Ethernet interface 1, referred to as Ethernet 1/1
Slot 1, serial interface 0, referred to as serial 1/0
Slot 1, BRI interface 0, referred to as BRI 1/0

Note The 2E 2-slot module described in this example provides both an attachment unit interface (AUI) and 10BaseT port. Only one of these ports can be used at a time. The module automatically detects which port, AUI or 10BaseT, is in use.

Voice Interface Numbering in Cisco 3600 Series Routers

Voice interfaces are numbered differently from WAN interfaces described in the previous section, "Unit Numbering." Voice interfaces are numbered as follows:

interface type chassis slot/voice module slot/voice interface

If you have a 4-channel voice network module installed in slot 1 of your router, the voice interfaces will be:

Slot 1, voice network module slot 0, voice interface 0, referred to as voice 1/0/0 (closest to chassis slot 0)
Slot 1, voice network module slot 0, voice interface 1, referred to as voice 1/0/1
Slot 1, voice network module slot 1, voice interface 0, referred to as voice 1/1/0
Slot 1, voice network module slot 1, voice interface 1, referred to as voice 1/1/1 (farthest from chassis slot 0)

Figure 1-5: Cisco 3600 Ser ies Unit N umbers

Cisco 2600 Series Interf ace Numbering

Each individual network interface on a Cisco 2600 series router is identified by a slot number and a unit number.

Slot and Unit Numbering

The Cisco 2600 series router chassis contains one slot in which you can install a network module. This is always slot 1.

Unit numbers identify the interfaces on the modules and WAN interface cards installed in the router. Unit numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top. Modules and WAN interface cards are identified by interface type, slot number, followed by a forward slash (/), and then the unit number; for example, Ethernet 0/0.

Figure 1-6 shows a router with a 2E 2-slot module in slot 1. One serial and one ISDN BRI WAN interface card are installed in the module.

Figure 1-6: Cisco 2600 Series Unit Numbers

Note WAN interface card slots (built into the chassis) are always numbered as slot 0, even if the interface card is installed in the slot labeled W1.

Figure 1-6 shows the following unit numbers:

First Ethernet interface, referred to as Ethernet 0/0
Token Ring interface, referred to as Token Ring 0/0
Slot W0, serial interface 0, referred to as serial 0/0
Slot W1, serial interface 1, referred to as serial 0/1
Slot 1, Ethernet interface 0, referred to as Ethernet 1/0
Slot 1, Ethernet interface 1, referred to as Ethernet 1/1
Slot 1, serial interface 0, referred to as serial 1/0
Slot 1, BRI interface 0, referred to BRI 1/0

Interface numbers usually begin at 0 for each interface slot, and continue from right to left and, if necessary, from bottom to top. However, interface numbering for the Cisco 2600 series routers and Ethernet/Token Ring network modules with two WAN interface card slots differs in the following ways:

WAN interface card slot numbers always appear as slot 0, even if the interface card is installed in the slot labeled W1.
WAN interface cards are numbered dynamically, starting with the first card installed. For example:
- If slot W0 is empty and slot W1 contains a 1-port serial WAN interface card, the interface number would be serial 0/0.
- If slot W0 contains a 2-port serial WAN interface card and slot W1 contains a 1-port serial interface card, serial 0/0 and 0/1 would reside in slot W0 and serial 0/2 would reside in slot W1.

Voice Interface Numbering in Cisco 2600 Series Routers

Voice interfaces are numbered differently from WAN interfaces described in the previous section, "Slot and Unit Numbering." Voice interfaces are numbered as follows:

interface type chassis slot/voice module slot/voice interface

If you have a 4-channel voice network module installed in slot 1 of your router, the voice interfaces will be:

Slot 1, voice network module slot 0, voice interface 0, referred to as voice 1/0/0 (closest to chassis slot 0)
Slot 1, voice network module slot 0, voice interface 1, referred to as voice 1/0/1
Slot 1, voice network module slot 1, voice interface 0, referred to as voice 1/1/0
Slot 1, voice network module slot 1, voice interface 1, referred to as voice 1/1/1 (farthest from chassis slot 0)

Before Starting Your Router

Before you power ON your router and begin to use the setup command facility, make sure you follow these steps:

Step 1 Set up the hardware as described in the documentation appropriate to your router.

Step 2 Configure your PC terminal emulation program for 9600 baud, 8 data bits, no parity, and 1 stop bit.

Step 3 Determine which network protocols you are supporting (for example, AppleTalk, IP, Novell IPX, and so on).

Step 4 Determine the following for each network protocol:

Addressing plan
Which WAN protocols you will run on each interface (for example, Frame Relay, HDLC, X.25, and so on)

Using the Setup Command Facility

The setup command facility displays from your PC terminal emulation program window.

To create a basic configuration for your router, do the following:

Complete the steps in the "Configuring Global Parameters" section.
Complete the steps in the "Configuring Interface Parameters" section that apply to your router and network.
Complete the steps in the "Completing the Configuration" section.

Note If you make a mistake while using the setup command facility, you can exit and run the facility again. Press Ctrl-c, and type setup at the enable mode prompt (2600#).

Configuring Global Parameters

Step 1 Power ON the router. The power switch is on the rear panel of the router, at the lower right corner, near the power cord.

Messages will begin to appear in your terminal emulation program window.

Caution
Do not press any keys on the keyboard until the messages stop. Any keys pressed during this time are interpreted as the first command typed when the messages stop, which might cause the router to power off and start over. It takes a few minutes for the messages to stop.

The messages look similar to the following:

Step 4 Enter a host name for the router (this example uses 2600):

Configuring global parameters:
 
  Enter host name [Router]: 2600
 
The enable secret is a password used to protect access to privileged EXEC and configuration modes. This password, after entered, becomes encrypted in the configuration.

Step 5 Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when viewing the configuration:

Enter enable secret: xxxx
 
The enable password is used when you do not specify an enable secret password, with some older software versions, and some boot images.

Step 6 Enter an enable password that is different from the enable secret password. This password is not encrypted (less secure) and can be seen when viewing the configuration:

Enter enable password: guessme
 
The virtual terminal password is used to protect access to the router over a network interface.

Step 7 Enter the virtual terminal password, which prevents unauthenticated access to the router through ports other than the console port:

ISDN BRI Line Config uration

Before using a router with an ISDN BRI interface, you must order a correctly configured ISDN BRI line from your local telecommunications service provider.

The ordering process varies from provider to provider and from country to country. However, here are some general guidelines:

Ask for two channels to be called by one number.
Ask for delivery of calling line identification, also known as caller ID or Automatic Number Identification (ANI).
If the router will be the only device attached to the ISDN BRI line, ask for point-to-point service and a data-only line.
If you plan to connect another ISDN device (such as an ISDN telephone) to the ISDN BRI line through the router, ask for point-to-multipoint service (subaddressing is required) and a voice-and-data line.

ISDN BRI Provisioning by Switch Type

ISDN BRI provisioning refers to the types of services provided by the ISDN BRI line. Although provisioning is performed by your ISDN BRI service provider, you must tell the provider what you want.

Table 1-2 lists the provisioning you should order for the router based on switch type.

Table 1-2: ISDN Pro visioning by Switch Type

Defining ISDN Service P rofile Identifiers

Some service providers assign service profile identifiers (SPIDs) to define the services subscribed to by an ISDN device. If your service provider requires SPIDs, your ISDN device cannot place or receive calls until it sends a valid SPID to the service provider when initializing the connection. A SPID is usually a seven-digit telephone number plus some optional numbers, but service providers may use different numbering schemes. SPIDs have significance at the local access ISDN interface only; remote routers are never sent the SPID.

Currently, only DMS-100 and NI-1 switch types require SPIDs. Two SPIDs are assigned for the DMS-100 switch type, one for each B channel. The AT&T 5ESS switch type may support SPIDs, but Cisco recommends that you set up that ISDN service without SPIDs.

If your service provider assigns you SPIDs, you must define these SPIDs on the router. To define SPIDs and the local directory number (LDN) on the router for both ISDN BRI B channels, use the following isdn spid commands:

Router(config-if)# isdn spid1 spid-number [ldn]
 
Router(config-if)# isdn spid2 spid-number [ldn]

Note Although the LDN is an optional parameter in the command, you may need to enter it so the router can answer calls made to the second directory number.

1-Port, 4-Wire 56-kbps DSU/CSU Configuration Setup

This section describes using setup command facility to configure a 1-port, 4-wire 56-kbps DSU/CSU WAN interface card.

Choosing Circuit-Switched or Dedicated-Line Service

The switched-56 WAN interface card is configured for dedicated or leased-line service by default, but it can also be configured for circuit-switched service. Depending on the type of data transmissions you typically use, you can configure the switched-56 WAN interface card for circuit-switched or dedicated-line service.

Generally, circuit-switched service is ideal for short duration data transmissions or as an alternative route if a dedicated line fails. For example, circuit-switched service is ideal for sending electronic mail messages or doing such tasks as updating inventory and ordering records from one network database to another at the end of each day.

Dedicated service is ideal for heavy network traffic. Dedicated service is ideal if you need a constant network connection or you need connection for more than eight hours per day.

Switched Mode

The following is an example of a 1-port, 4-wire 56-kbps DSU/CSU switched-mode configuration using the setup command facility:

Do you want to configure Serial0/0 interface? [yes]:
   Some encapsulations supported are 
             ppp/hdlc/frame-relay/lapb/atm-dxi/smds/x25
  Choose encapsulation type   [ppp]:
 
Switched 56k interface may either be in switched/Dedicated mode
  Choose from either (switched/dedicated)  [switched]:
  
The following switched carrier types are to be set when in switched mode
(at&t, sprint or other)
  Choose carrier (at&t/sprint/other)  [other]:
 
Do you want to map the remote machine's ip address in dialer map? [yes]:
     IP address for the remote interface : 1.0.0.2
Do you want to map the remote machine's ipx address in dialer map? [yes]:
    IPX  address for the remote interface : 40.0060.34c6.90ed

Note The setup command facility will ask for only one telephone number for both IP and IPX (if enabled).

Please enter the phone number to call : 1234567890
  Configure IP on this interface? [yes]:
    IP address for this interface: 1.0.0.1
    Subnet mask for this interface [255.0.0.0] :
    Class A network is 1.0.0.0, 8 subnet bits; mask is /8

Dedicated Mode

The following is an example of a 1-port, 4-wire 56-kbps DSU/CSU dedicated-mode configuration using the setup command facility:

Do you want to configure Serial0/0 interface? [yes]:
 
  Some encapsulations supported are 
            ppp/hdlc/frame-relay/lapb/atm-dxi/smds/x25
  Choose encapsulation type   [ppp]:
 
  Switched 56k interface may either be in switched/Dedicated mode
  Choose from either (switched/dedicated)  [switched]: dedi
 
  When in dds mode, the clock for sw56 module can either from line/internal.
  Choose clock from (line/internal)  [line]:

Note If internal is selected, speed cannot be set to "auto." Auto-sensing is only allowed when the clock source is line.

When in dds mode, the clock for sw56 module can either from line/internal.
  Choose clock from (line/internal)  [line]: internal
  Warning: internal can be choose only when connected back to back.
 
  Serial interface needs clock rate to be set in dce mode.
  The following clock rates are supported on the serial interface.
 
        auto, 2.4, 4.8, 9.6, 19.2, 38.4
        56, 64
 
  choose clock rate from above  [56]:
  Configure IP on this interface? [yes]:
    IP address for this interface: 1.0.0.1
    Subnet mask for this interface [255.0.0.0] :
    Class A network is 1.0.0.0, 8 subnet bits; mask is /8
