Cisco Security Device Manager (SDM) Quick

Start Guide

This document accompanies the Quick Start Guide for your Cisco router. It describes Security Device

Manager (SDM) and shows you how to use it to configure your Cisco IOS.

Cisco Security Device Manager (SDM) is an easy-to-use device management tool that allows you to

configure Cisco IOS security features through an intuitive web-based graphical user interface.

Note This document contains the latest information on how to use SDM to give your router an initial

configuration. If the Quick Start Guide that came with your router contains SDM startup instructions, do

not use those instructions. Use this document instead.

If you don’t want to use SDM to configure the router, see I Want to Use the Cisco IOS Startup Sequence.

Cisco Security Device Manager (SDM) Quick Start Guide 78-16254-01

Use SDM to Configure the Router

This section explains how to use the SDM Startup wizard to deploy your router with a working LAN and

WAN configuration. Once the router is deployed you can use SDM to further configure LAN and WAN

interfaces, dynamic routing, Network Address Translation (NAT), firewalls, Virtual Private Networks

(VPNs), and other features on your router. SDM runs under Internet Explorer version 5.5 or later, on a

PC that is running Microsoft Windows XP, Windows 2000, Windows ME, Windows NT 4.0 (with

Service Pack 4), or Windows 98. SDM runs under Netscape 4.79 on a PC that is running Microsoft

Windows XP, Windows 2000, Windows ME, or Windows NT 4.0 (with Service Pack 4).

Task 1: Install Interface Cards, and Cable the Router

Before SDM can be used to configure the router, you must install all the necessary hardware accessories

that are applicable to your router, such as WAN interface cards (WICs), Network Modules (NMs), or

AIM cards that you will use to connect to the network. Refer to the Quick Start Guide for your router

for instructions on installing these interface cards, cabling the router, and verifying that all the

connections are working properly.

Task 2: Set Up the PC

You have to set up the PC to communicate with SDM. SDM is shipped with a default configuration file

that assigns an IP address to a LAN interface on the router, and you must configure the PC to be on the

same subnet as the router’s LAN interface.

Because the router is not preconfigured as a DHCP server, you must assign a static IP address to the PC.

Assign an IP address in the range of 10.10.10.2 to 10.10.10. 6 to the Ethernet port of the PC, as shown

in Figure 1. Use the subnet mask 255.255.255.248. The lowest numbered Ethernet interface of the router

is preconfigured with the IP address 10.10.10.1.

Figure 1 Conﬁgure the PC with a Static IP Address in the 10.10.10.0 Subnet

Use an Ethernet cable to connect the PC’s Ethernet adapter to the lowest-numbered Ethernet port on the

router. See Table 1 to determine which port to connect the PC to, and what type of cable to use. The

Ethernet LED for your router listed in Table 1 turns on when the connection is made. Although Figure 1

does not show an Ethernet switch between the PC and the router, an Ethernet switch can be used with

straight through cables.

Figure 2 Router Home Page

If the router home page does not appear when you enter the URL https://10.10.10.1

(or http://10.10.10.1), test the connection between the PC and the router by doing the following:

•Check that the Power LED on the router is on, and that the LED for the port to which you connected

the PC is on, indicating an active Ethernet connection between the router and the PC. See Table 1 to

determine which LED this is. If this LED is not lit, verify that you are using a crossover cable to

connect the PC to the router, or that you are using a straight-through cable between the router and

the switch.

•If the Launch page still does not appear, verify that the web browser’s “work offline” option is

disabled. In Internet Explorer, click the File menu, and verify that the “work offline” option is

unchecked. In Netscape, the default selection in the File menu is set to “work online.”

•If the Launch page still does not appear, verify that the file sdm.tar is loaded into Flash memory.

Open a Telnet session to 10.10.10.1, entering the username cisco and the password cisco. Enter the

show flash command to verify that sdm.tar is loaded in Flash memory.

•If the web page still does not appear, verify that the PC is configured with a static IP address.

Step 4 A window appears that informs you that Verisign certifies that this is a Cisco application. Click Yes,or

click Grant to accept the certificate and proceed. If additional certificate windows appear , click Grant

to accept the certificates.

Step 5 The SDM Launch page appears after a short time (Figure 3). Leave this window open and wait for the

next window.

Figure 3 SDM Launch Page

Step 6 A window appears that provides information about the browser and its settings. That window also

informs you that SDM will open in another window. You can close this window and wait for the SDM

Startup Wizard page to appear.

Step 7 When the SDM Startup wizard appears, click Next to begin configuring the router. Use the wizard to

give the router a name, and to configure a LAN interface, a WAN interface, and secure the router. You

configure the LAN IP address, and you can create a DHCP server to provide IP addresses to the hosts on

the private (inside) network. To configure the WAN, you need to enter the IP address and other

parameters provided by your Internet service provider (ISP).

Tip The Startup wizard will ask you to enter an enable secret password to control access to the Cisco IOS.

Be sure to write down or remember the enable secret password that you enter. It is not shown in the

enable password field or in the summary window, and it cannot be reset without erasing the router

configuration.

Step 8 When the Summary window appears, write down the LAN IP address, the username and the user

password that you entered, and click Finish. You will need this information to reconnect to the router

and use SDM to perform additional configuration.

Step 9 Exit SDM and complete Task 4 to reconfigure the PC and to reconnect to SDM, using the new IP address

you gave to the LAN interface.

Task 4: Assign a New IP Address to the PC, and Restart SDM

Follow these steps to assign a new IP address to the PC and to continue using SDM:

Cisco Security Device Manager (SDM) Quick Start Guide 78-16254-01

Use SDM to Configure the Router

Step 1 Assign a new IP address to the PC’s Ethernet interface; place it on the same subnet as the router’s

Ethernet port, which you assigned in Step 7 of Task 3. See Figure 4 for an example configuration. If you

configured a DHCP server on the router, configure the PC to obtain an IP address automatically.

Figure 4 Conﬁgure the PC with an IP Address on the New Subnet

Figure 4 shows that you can connect the PC directly to the router using a crossover cable, or connect it

to a switch using a straight through cable.

Step 2 Open a web browser on the PC, and enter the SDM URL, using the new IP address that you gave the

LAN interface (https://new-IP-address). In the example shown in Figure 4, you would enter the

following:

https://172.16.30.1

The https://... specifies that the Secure Socket Layer (SSL) protocol be used for a secure connection.

You can use http://... if SSL is not available.

Step 3 Enter the username and password that you specified in Step 7 in the “Task 3: Start SDM, and Complete

the Startup Wizard” section on page 3.

The SDM Overview window appears, as shown in Figure 5.

To continue configuring your router, see the “Using SDM” section on page 7.

You’re Done! Where to Go from Here

Now that you have used SDM to give your router an initial configuration, you can continue to use SDM

to configure additional features or modify existing feature configurations.You can use the SDM URL to

start SDM and then add to, or modify, your router’s configuration at any time.

For More Information About SDM and About Your Router

For additional information about SDM features, refer to the SDM online help. Additional information

about SDM is also available on the SDM website at http://www.cisco.com/go/sdm. This website

provides access to detailed information about SDM, including an SDM FAQ, data sheet, customer

presentation, Flash demo, and links to technical documentation and product updates.

Refer to the Quick Start Guide for your router for other procedures, such as connecting a PC to the router

console port so that you can use the CLI when you need to, and using the router LEDs to verify

installation. The Quick Start Guide may also contain important warranty information.

I Want to Use the Cisco IOS Startup Sequence

If you have already configured the router using SDM, you don’t need to read this section.

Because SDM uses a default configuration file, your router will not execute the standard Cisco IOS

startup sequence. You can use this section to run Cisco IOS setup utility and take advantage of a TFTP

or BOOTP configuration download, or use other features available through the standard Cisco IOS

startup sequence. It also tells you what to do if you want to use SDM in the future.

SDM has created a default configuration for your router. The configuration does the following:

•Provides an IP address for your Fast Ethernet interface, enabling an interface to your LAN

•Enables your router’s HTTP/HTTPS server, allowing HTTP access from your LAN

•Creates a default username (cisco) and password (cisco) with privilege level 15

•Enables Telnet/SSM access to the router from your LAN

If you want to erase the existing configuration and take advantage of the Cisco IOS startup sequence,

perform the following steps. SDM will remain on the router.

Step 1 Connect the light blue console cable, included with your router, from the blue console port on your router

to a serial port on your PC. Refer to your router’s Hardware Installation Guide for instructions.

Step 2 Connect the power supply to your router, plug the power supply into a power outlet, and turn on your

router. Refer to your router’s Quick Start Guide for instructions.

I Want to Use the Cisco IOS Startup Sequence

Step 3 Use a terminal emulation program on your PC, with the terminal emulation settings of 9600 baud, 8 data

bits, no parity, 1 stop bit, and no flow control, to connect to your router.

Step 4 At the prompt, enter the enable command. The default configuration file does not configure an enable

password.

yourname> enable

yourname#

Step 5 Enter the erase startup-config command.

yourname# erase startup-config

Step 6 Confirm the command by pressing Enter.

Step 7 Enter the reload command.

yourname# reload

Step 8 Confirm the command by pressing Enter.

After you press enter, the router will begin executing the standard startup sequence. If you want to be

able to use SDM to perform subsequent configurations for the router, you must use the CLI to add

statements to the configuration file. See the “I Want to Install or Enable SDM on the Router” section for

this information.

I Want to Install or Enable SDM on the Router

In order to use SDM in the future, you must configure the router to support web-based applications,

configure it with a user account defined with privilege level 15, and configure it to support the Telnet and

SSH protocols.

•The router’s HTTP/HTTPS server must be enabled, using the following Cisco IOS commands:

ip http server

ip http secure-server

ip http authentication local

If the router uses an IPSec IOS image, the HTTPS server is enabled. Otherwise only the HTTP

server is enabled.

•SDM requires a user account that is defined with privilege level 15 (enable privileges):

username <

username

> privilege 15 password 0 <

password

Note For security purposes, the user account that you define should be different from the default

one used in the example above.

•SSH/Telnet must be configured for local login and privilege level 15:

line vty 0 4

privilege level 15

transport input telnet

transport input telnet ssh

•Local logging should (optionally) be enabled to support the log monitoring function:
