As I said in this thread:

You need to open a TAC service request so more debugging can be performed. You are seeing some kind of timeout issue, but there are no known timeout problems in RME 4.3. If you want to manually verify that everything is working right, test the following:
* SSH to the device from the RME server, and login using the same credentials that are in DCR.
* Become enabled using the enable password configured in DCR. If you are enabled by default when logging in, you can skip this step.
* Run the "show privilege" command, and verify the output says you are at level 15.
* Run the command "term length 0" and verify it succeeds.
* Run the command "show running" and verify you can see the whole config without the parser stopping at a "More" prompt.
* Run the command "show startup" and verify the same as above.
Performing each one of these steps exactly as I have said in the exact order is critical. If they all work, then open a TAC service request. If not, fix the problem causing the step in question to fail.
