So, if you say TOS '001', there is an increasing likelihood that *all* your links will have TOS '001'; if you have TS traffic, it will only go over TS links. The probe wouldn't return you much useful information in that case! On the other hand, maybe it will be useful in the short term; I just don't have a good feel for how useful. I'd only like to add features (i.e. complexity) to the architecture if there is a demonstrated need, and I don't recall any agitation for it. Is there need and use for this? Also, as Jeff points out, let's not divert effort from the MTU stuff at hand. We have to get this out! Noel
