Seems to have all the bases covered. For consistency, I'd swap the latter values (although I doubt complement will have much use): 00 : global conf is used 01 : complement global conf 10 : Timestamps OFF for this route 11 : Timestamps ON for this route And the documentation should make it clear that global 10 and 11 override per route 10 and 11.
