I agree that it would help if you post the output showing what you are doing and what the results are.
One thing that might produce the results that you describe is if devices in the path from your switch to the destination are configured with no ip unreachable. Remember that the way that traceroute works is that it sends probe packets controlling the Time To Live. It depends on the devices along the path to reduce the TTL and send error messages when TTL goes to zero. This is how we learn the steps along the path. But if the device is configured with no ip unreachable then when TTL goes to zero it discards the packet but does not send the error message. The question marks show steps in the path from which it did not receive responses. So in this case ping will work because you can get to the destination, but traceroute will not show the steps along the way.
