this document also lists Cat3750 as being supported from 12.2(20)SE onwards.
But the TAC states, that there's no support at all on 3750.

I did several times - unfortunately it seems that they are instead going
to remove all traces of SFP optical monitoring from the documentation and
noone is willing to fix the problem.
It's ridiculous - the feature is in the IOS, works fine (except one minor
problem) and instead of fixing the bug it seems this useful feature
is going to completely disappear.
Anyone could please help?
Thanks & kind regards,
