I've been trying to use SDM for testing purposes (for CCNP exams training actually). I have found documents on cisco.com and did all the necessary configuration on the router and on PC ( including Java version).
When I open a web browser (I tried Mozilla and IE) and type the router's address, I see the prompt asking me my username and password and the engine starts to load. But as soon as the main SDM screen appears, the browser page freezes and you are no more able to click on icons and reach the menus.
Thanks in advance for your help.
