I suppose cisco implementation is also hw specific (for example on 1000x
esr "show hardware pxf cpu cef" gives "Shadow 12-8-4-4-4 Toaster Mtrie".
Also . it's kind funny that ( in my experience ) Cisco wasn't able to
provide decent and fast gear for ISP ( let command "show pxf crash" be
an example ... ) in last years given ( i think so  ) lot's of more cash
for R&D .
