If SDM files are present, try starting SDM. Open a web browser and enter the IP address of the router in the browser's address field, as shown below:
http://router_IP_address
For example, if the router's IP address is 10.20.55.1, you would enter the following command:
http://10.20.55.1
Enter the username and password of the level 15 user you configured in Task 3. When certificate windows appear, click Yes or click Grant to accept the certificates.
