The reason that the CX-FEIP-2TX is so inexpensive is that it is
interesting mainly as a curiousity of transitional technology.

A CX-FEIP-2TX is VIP1, not a VIP2 (even a 2-15 or 2-20), and is
incapable of being upgraded to do distributed anything, (cef, flow,
whatever).  It barely does full-duplex at line rate on one port, let
alone two.

Its sole use, if you happen to like to keep old hardware around, is
that it will work in a 7000/7010 with RP/[S]SP, (ie, not an RSP).  You
can use them in a 7500 (or a 7000 with an RSP7k), but why would you
want to?
