It is prohibited for a man to shave his beard, and it is disliked for him to take more than a fist length from his beard. And the sunnah is for him to strongly trim his mustache, such that it is not quite totally shaved, but trimmed very short.
So in other words, the official position of the school is as follows:
More than or equal to fist length beard = Sunnah (recommended)
Less than fist length = Makrooh (disliked)
Total shaving = Haram (prohibited)
Short trimming of mustache = Sunnah (recommended)
