Your question is overly vague – please cite a specific reference; please give some context.
In general, however:
“Policy” is what you want to do; “mechanism” is the how that lets you do it.
IMHO…
PS:
Here is (one of?) the original paper(s) that refers to “separation of policy and mechanism”:
HYDRA – The kernel of a multiprocessor operating system, William Allan. Wulf
Here’s another (slightly more amusing) discussion, from the “politically incorrect” Mick O’Pedia:
