I can not speak to the details of these hidden commands. But I can say that in general there are a number of commands that are not documented, and therefore are "hidden". Many of them are inserted because they provide helpful diagnostic functions. But they may not have been through the level of testing and evaluation for Cisco feeling comfortable in making them generally available and documented. Because they are not documented they do not qualify for support assistance if you use them and something unexpected happens.

I would advise you to be cautious about using the undocumented commands. Many of them are helpful and useful, but some of them are dangerous.
