Re: What is this Cisco process?

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.

Thanks again for the response... you solved my problem.

Cheers,

Joe
