it seems that with the EX you have to play the 'upgrade to the next
daily image' game, a lot.

since this is a tcam based platform it's not just 'terms' that matter,
but the combinatorial effect of the contents of the terms... A that
references 2 sources & 2 destinations is 4 entries in the TCAM. Add
ports/protocols and that number can increase, dramatically.

there's a rather short set of entries permitted ... and you can't
allocated specifically to the 'pfe' (the equivalent part on the EX), of
which there are (I believe) 3 on the 4200.
