[c-nsp] IPv6 on MSFC2

[Church, Chuck]

Thanks Oli.  From what I've read, the Enhanced FlexWAN can do about
640,000 PPS per slot.  I guess the non-enhanced version is about half
that.  Assuming memory isn't an issue on the FlexWAN, are these PPS
numbers accurate for IPv6 also, or just IPv4?  Also, how the heck does
one console into the flexwan to check CPU?  I've tried a variety of
remote, session, and attach commands.  Session slot slot# processor
proc# seems to try, but I'm not sure of the processor number.  Tried
both 0 and 1, both time out as it tries to connect to a loopback
address.  It's a Sup2 in hybrid mode, CatOS 6.4, IOS 12.1E on MSFC.

Thanks again,

Chuck

I've seen tests with ~200kpps on Sup2, but then your MSFC CPU will be at
90+%, so not really something I'd do in production ;-)

Filling an OC3 with some IMIX packet distribution should work, however,
not sure about the Flexwan as this also needs to be checked here.
