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:

Before You Begin

Using the Setup Command Facility

Configuring Global Parameters

Configuring Interface Parameters

Completing the Configuration

Where to Go Next

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 ""Cisco IOS Software Basics" to familiarize yourself with the command-line interface (CLI) and then proceed to PART II for instructions on configuring your MWR 1941-DC router.

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 understanding boot images, interface numbering, and knowing what you should do before starting your router.

Understanding Boot Images

The first file on the compact flash device in slot0: must be the Cisco IOS software image that you want to use. If it is not, the MWR 1914-DC router will not be able to boot.

If you need to upgrade or replace the compact flash, be sure to follow the procedures in the Cisco MWR 1941-DC Mobile Wireless Router Hardware Installation Guide.

Understanding MWR 1941-DC Router Interface Numbering

Each network interface on a Cisco MWR 1941-DC router is identified by a slot number and a port number.

Figure 3-1 shows an example of interface numbering on a Cisco MWR 1941-DC router with the following configuration for a Cell Site DCN implementation:

A VWIC in three of the three VWIC slots

A 4-port asynchronous/synchronous serial network module in slot 1

Two built-in Fast Ethernet interfaces

Figure 3-1 Cisco MWR 1941-DC Router Port Numbers

Slot and Port Numbering

The Cisco MWR 1941-DC router chassis contains the following LAN and WAN interface types:

Two built-in Fast Ethernet LAN interfaces

Three slots in which you can install Voice/WAN interface cards (VWICs)

One slot in which you can install a network module

The slot numbers are as follows:

0 for all built-in interfaces

0 for all built-in VWIC slots

1 for the network module slot

The numbering format is:

Interface type Slot number/Interface number

Interface (port) numbers begin at 0 for each interface type, and continue from right to left.

The two built-in Ethernet 10/100 interfaces are Fast Ethernet 0/0 and Fast Ethernet 0/1.

The slot number for all VWIC interfaces in the built-in VWIC slot is always 0. (The W0, W1, and W2 slot designations are for physical slot identification only.) Interfaces in the VWICs are numbered from right to left, starting with 0/0 for each interface type, regardless of the physical VWIC slot in which the VWICs are installed.

For example, if you have a VWIC in two of the VWIC slots (W0 and W1), then the interfaces are:

Serial 0/0 and Serial 0/1 in physical slot W0

Serial 0/2 and Serial 0/3 in physical slot W1

However, if you install a VWIC in physical slot W1 (leaving slot W0 empty), the interfaces in slot W1 are Serial 0/0 and Serial 0/1. If you then add a VWIC to slot W0, the interface numbering will shift. The configuration that you created for interfaces Serial 0/0 and Serial 0/1 will now be applied to the VWIC in slot W0 and you will need to create a new configuration for the interfaces that you previously configured on W1 (which will now be Serial 0/2 and Serial 0/3).

The slot number of WIC/VWIC interfaces installed in slot 1 using a WAN network module is always 1 and the interfaces are always numbered from the right to left.

The slot number for all network module interfaces is always 1 and the interfaces are always numbered from right to left starting with 1/0.

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 and connect the console and network cables as described in the Cisco MWR 1941-DC Router Hardware Installation Guide.

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


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.

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 (1900#).


Configuring Global Parameters


Step 1 Power ON the router, see the Cisco MWR 1941-DC Router Hardware Installation Guide.

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:


Note The messages vary, depending on the Cisco IOS software image and interface modules in place in your router. The screen displays in this section are for reference only and might not exactly reflect the messages on your console.

To complete your router configuration, do the following:


Step 1 A setup command facility prompt asks if you want to save this configuration.

[0] Go to the IOS command prompt without saving this config.
[1] Return back to the setup without saving this config.
[2] Save this configuration to nvram and exit.

Enter your selection [2]:
Building configuration...
Use the enabled mode 'configure' command to modify this configuration.


Press RETURN to get started!

If you answer no, the configuration information you entered is not saved, and you return to the router enable prompt. Type setup to return to the System Configuration Dialog.

If you answer yes, the configuration is saved and you are returned to the EXEC prompt.

Step 2 When the messages stop displaying on your screen, press Return to get the command line prompt.


The 1941-1> prompt indicates that you are now at the command-line interface (CLI) and you have just completed a basic router configuration. However, this is not a complete configuration. You must configure additional parameters using the Cisco IOS software CLI as described in Part 2, "Implementing the MWR 1941-DC Router in an IP-RAN".
