You are correct in the way the L3 engine works in terms of external
and internal ports. However i do not agree that if you have a
organisation and support team that are uses to CatOS to change to IOS
based SP engine such as the II+, III and IV. Whilst i agree that is
the way fwd if you are sticking with the 4k then yes migrate. Also if
you are not too worried about over-subscription with 2 gig L3 uplink
to matrix (Backplane) then there is no issues.
