Yes - And I have previously wondered if it was worth figuring out how to maintain or mask previous TOS settings. Hmmmm - one of these days maybe. I always use FTOS to test routing and force certain behaviour on DIffServ networks. So I never really cared that it stomped all over the TOS field. But now with the shoehorning (aka TOS split to DS and ECN and ...) I wonder if maybe a more flexible multiset mechanism that allows you to mask old values for additiona or changing would work. Kind of letting you choose which settings to allow. > > Taka > Maciek -------------------------------------------------- Matthew G.
