Among these Sunnah, some are fard like Salah, Hajj, Zakat (subject to some conditions) and some are mustahab (nafal with emphasis or recommended) like matters of customs and etiquettes & Qurbaani (animal sacrifice) etc. Intentional violation of an emphatic or recommended Sunnah at best can result in a minor sin.
