Lab 5.2.3 Configuring an ISR with SDM Express

Step 1: Configure the PC to connect to the router and then launch Cisco SDM
a. Power up the router.
b. Power up the PC.
c. Disable any popup blocker programs. Popup blockers prevent SDM Express windows fromdisplaying.
d. Connect the PC NIC to the FastEthernet 0/0 port on the Cisco 1841 ISR router with the Ethernet cable.
NOTE: An SDM router other than the 1841 may require connection to different port in order to access SDM.
e. Configure the IP address of the PC to be with a subnet mask of
f. SDM does not load automatically on the router. You must open the web browser to reach the SDM.Open the web browser on the PC and connect to the following URL:
NOTE 1 – If browser connection to router fails: If you cannot connect and see the login screen, check your cabling and connections and make sure the IP configuration of the PC is correct. The router may have been previously configured to an address of on the Fa0/0 interface. Try setting the IP address of the PC to with a subnet mask of and connect to using the browser. If you have difficulty with this procedure, contact your instructor for assistance.
If the startup-config is erased in an SDM router, SDM will no longer come up by default when the router is restarted. It will be necessary to build a basic router configuration using IOS commands.Refer to the procedure at the end of this lab or contact your instructor.
g. In the Connect to dialog box, enter cisco for the username and cisco for the password. Click OK. The main SDM web application will start and you will be prompted to use HTTPS. Click Cancel. In the Security Warning window, click Yes to trust the Cisco application.
h. In the Welcome to the Cisco SDM Express Wizard window, read the message and then click Next.
i. Verify that you are using the latest version of SDM. The initial SDM screen that displays immediately after the login shows the current version number. It is also displayed on the main SDM screen shown below, along with IOS version.
NOTE 2: If the current version is not 2.4 or higher, notify your instructor before continuing with this lab. You will need to download the latest zip file from the URL listed above and save it to the PC. From the Tools menu of the SDM GUI, use the Update SDM option to specify the location of the zip file and start the update.
NOTE 3 – If SDM Express Wizard fails to start: If you connect to the router and SDM Express starts but the SDM Express Setup Wizard shown above does not start automatically, the router may be partially configured and needs to be reset to its factory defaults. If the SDM Express main screen is displayed, choose the Reset to Factory Defaults option, repeat Steps 1a through 1e, and log in again. If the full SDM application starts (not SMD Express), choose the Reset to Factory Defaults option from the File menu on the main SDM screen, repeat Steps 1a through 1e, and log in again. If you have difficulty with this procedure, contact your instructor for assistance.
Also note that the Windows XP computer you are using must have Internet Explorer 5.5 or higher and SUN Java Runtime Environment (JRE) version 1.4.2_05 or later (or Java Virtual Machine (JVM) If it does not, SDM will not start. You will need to download and install JRE on the PC before continuing with the lab.

Step 2: Perform initial basic configuration
a. In the Basic Configuration window, enter the following information. When you complete the basic configuration, click Next to continue
· In the Host Name field, enter CustomerRouter.
· In the Domain Name field, enter the domain name
· Enter the username admin and the password cisco123 for SDM Express users and Telnet users. This password gives access to SDM locally, through the console connection, or remotely using Telnet.
· Enter the enable secret password of cisco123. This entry creates an encrypted password that prevents casual users from entering privileged mode and modifying the configuration of the router using the CLI.
b. From the Router Provisioning window, click the radio button next to SDM Express and then clickNext.

Step 3: Configure the LAN IP address
In the LAN Interface Configuration window, choose FastEthernet0/0 from the Interface list. For interface FastEthernet 0/0, enter the IP address of and subnet mask of You can also enter the subnet mask information in a different format: entering a count of the number of binary digits or bits in the subnet mask, such as or 24 subnet bits.

Step 4: De-select DHCP server
At this point, do not enable the DHCP server. This procedure is covered in a later section of this course. In the DHCP server configuration window, ensure that the Enable DHCP server on the LAN interface check box is cleared before proceeding. Click Next to continue.

Step 5: Configure the WAN interface
a. In the WAN Configuration window, choose Serial0/0/0 interface from the list and click the Add Connection button. The Add Connection window appears.
NOTE: With the 1841 router, the serial interface is designated by 3 digits – C/S/P, whereC=Controller#, S=Slot# and P=Port#. The 1841 has two modular slots. The designation Serial0/0/0 indicates that the serial interface module is on controller 0, in slot 0, and that the interface to be used is the first one (0). The second interface is Serial0/0/1. The serial module is normally installed in slot 0 but may be may be installed in slot 1. If this is the case, the designation for the first serial interface on the module would be Serial0/1/0 and the second would be Serial0/1/1.
b. From the Add Serial0/0/0 Connection dialog box, choose PPP from the Encapsulation list. From the Address Type list, choose Static IP Address. Enter for the IP address and for the Subnet mask. Click OK to continue. Notice that this subnet mask translates to a /27, or 27 bits for the mask.
c. Notice that the IP address that you just set for the serial WAN interface now appears in the Interface List. Click Next to continue.
d. Enter the IP address as the Next Hop IP Address for the Default Route. Click Next to continue.
e. Ensure that the check box next to Enable NAT is cleared. This procedure is covered in a later section of this course. Click Next to continue.

Step 6: Enable the firewall and security settings
a. Depending on the router IOS version, the next step may be Firewall Configuration. In the Firewall Configuration window, click the radio button that enables the firewall and then click Next. The Security Configuration window appears.
b. Leave all the default security options checked in the Security Configuration window and then click Next.

Step 7: Review and complete the configuration
a. If you are not satisfied with the Cisco SDM Express Summary, click Back to fix any changes and then click Finish to commit the changes to the router.
b. Click OK after reading the Reconnection Instructions. Save these instructions to a file for future reference, if desired.
NOTE: Before the next time you connect, you will need to change the IP address of the PC to be compatible with the new address that you configured to FastEthernet 0/0. The Reconnectioninstructions are shown below.
c. When the delivery of the configuration to the router is complete. Click OK to close Cisco SDM Express.

Step 8: Reflection
a. What feature makes configuring the router easy?
b. Summarize the steps that are configured by the Cisco SDM Express
SDM router basic IOS configuration to bring up SDM
If the startup-config is erased in an SDM router, SDM will no longer come up by default when the router is restarted. It will be necessary to build a basic config as follows. Further details regarding the setup and use of SDM are can be found in the SDM Quick StartGuide:
1) Set the router Fa0/0 IP address
(This is the interface that a PC will connect to using a browser to bring up SDM. The PC IP address should be set to
NOTE: An SDM router other than the 1841 may require connection to different port in order to access SDM.
Router(config)# interface Fa0/0
Router(config-if)# ip address
Router(config-if)# no shutdown
2)  Enable the HTTP/HTTPS server of the router, using the following CiscoIOS commands:
Router(config)#ip http server
Router(config)#ip http secure-server
Router(config)#ip http authentication local
3) Create a user account with privilege level 15 (enable privileges).
Router(config)# username privilege 15 password 0
Replace and with the username and password that you want to configure.
4)  Configure SSH and Telnet for local login and privilege level 15:
Router(config)#line vty 04
Router(config-line)# privilege level 15
Router(config-line)# login local
Router(config-line)# transport input telnet
Router(config-line)# transport input telnet ssh
Router(config-line)# exit
