Initial Configuration Using Cisco Router and Security Device Manager
This section explains how to use Cisco Router and Security Device Manager (SDM) to configure your router. If SDM has been
installed on your router, the following messages appear at the end of the startup sequence:

SDM is a web-based configuration tool that allows you to configure LAN and WAN interfaces, routing, Network Address
Translation (NAT), firewalls, Virtual Private Networks (VPNs), and other features on your router. SDM runs on a PC connected
to the router through an Ethernet or Fast Ethernet interface, and it requires a web browser, either Internet Explorer version 5.5
or later or Netscape version 4.79. SDM is compatible with Microsoft Windows 2000, Windows NT 4.0 (with Service Pack 4),
Windows 98, Windows ME, and Microsoft Windows XP.

To configure your router by using SDM, first assign an IP address to the Ethernet port of the PC as directed in the “Assign a
Static IP Address to the PC” section, and then start SDM as described in the “Start SDM” section on page 25.

Assign a Static IP Address to the PC
Assign a static IP address in the 10.10.10.0 subnet to the Ethernet port of the PC. (See Figure 20.) The recommended IP address
for this interface is 10.10.10.2. The Fast Ethernet 0/0 interface of the router is preconfigured with the IP address 10.10.10.1.

If Your Router Has No Ethernet Adapter in Slot 0
Cisco 3620 and Cisco 3640 routers have no built-in Ethernet ports. However, many of these routers ship with a Fast Ethernet
network module in chassis slot 0. The SDM default configuration file assumes this to be the case. If your router has no Ethernet
module in chassis slot 0, you need to do one of the following:

module in chassis slot 0, you need to do one of the following:
•
•
Assign IP address 10.10.10.1 to an Ethernet port in a different chassis slot. To do this, perform the following steps:
Note
These steps should be performed only when there is no Ethernet-capable network module in chassis slot 0.
Step 1
Log on to the router through the console port, using the user name sdm, and password sdm.
Step 2
Enter Enable mode using the password sdm.
Step 3
Enter the show running-config command to verify that Ethernet port 0/0 is configured with IP address 10.10.10.1.
If Ethernet port 0/0 is not configured with IP address 10.10.10.1, SDM is not installed on your router, and you must
use the setup command facility or the command-line interface to configure the router.

Step 4
Enter configuration mode.

Step 5
Enter interface configuration mode for Ethernet interface 0/0.
yourname (config)#
interface FastEthernet 0/0
yourname (config-if)#
Step 6
Remove IP address 10.10.10.1 from Ethernet interface 0/0.
