Ingen, How did you know this? And I quote "Well, I have no direct experience with the 3560, but SFF-8472 is a spec that includes diagnosting monitoring of SFPs...". Really am I missing some secret search engine? Is google not the answer? Please do let me know because if it was from an online resource I want to know what it is.
