How to Configure SDM Express on Cisco Router
After you have made the necessary preparations for the installation, follow the steps below to set up the SDM now.
Start the GNS3 program and create a new project.
Drag and drop a Router, Switch and Host into the GNS3 workspace.
Wire all devices in the topology as follows.
You need to add a flash disk to the router because there is no disk defined by default in GNS3.
Right-click on the router, click configuration and then click the Memories and Disks tab.
On the Memories and Disks tab, specify the Flash Disk size as shown below, and then click OK.
Open the CLI console window by double-clicking on the router and run the show file system command to check the Flash Disk.
The flash disk is not in use because it is not formatted.
To format the router’s Flash Disk, type erase flash: and then press Enter.
You can check that the disk was formatted successfully from the image below.
To run the SDM, perform the following commands in the Router.
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#interface fastethernet 0/0
R1(config-if)#ip address 192.168.8.1 255.255.255.0
R1(config)#ip http server
R1(config)#ip http secure-server
R1(config)#ip http authentication local
R1(config)#username cisco privilege 15 password cisco123
R1(config)#line vty 0 4
R1(config-line)#privilege level 15
R1(config-line)#transport input telnet
Configure the TCP/IP settings of the virtual machine that you added to the topology.
At the same time, check that the network card of the virtual computer is VMnet3.
Test the connection by pinging the Cisco Router from the virtual machine.
To install JAVA 6u17 on the virtual machine, run the setup file as an administrator.
After installing JAVA JRE, go to Control Panel / Java / Java Control Panel and click the View button on the JAVA tab in the window that opens.
Then enter -Xmx256m in Runtime Parameters and save it.
Run the setup file as an administrator to start the SDM installation.
In the Wizard window, click Next.

To bypass the security certificate error, select the trusted content option and click the Yes button.
Re-enter the user name and password of the router.
The management application scans the current settings on the router.
The application suggests changing the user name and password you created. In this step, create a new user name and password.
Enter the user account you just created for the connection.
The application sends commands to the Router to create a new user.
Re-enter your account information for Java access permission.
After completing the installation steps, you can now connect and manage your Router via LAN or WAN.
In addition, check the version of the SDM program.
At the router’s CLI prompt, execute the show flash: command and examine the SDM-related files copied into the Flash Disk.
You can also check the Flash Disk size by applying the show file system command.
