Cisco ME1200 iCLI

ME1200 expert, who gave us some hidden commands to enter.
Log in to the default shell, and then enter:
v i e
v i v
(note there’s a space between each letter, hit enter after each line) That got us to the iCLI interface, so hopefully it will work for you too.

I believe the newer images for this device drop into a normal IOS by default.
