[c-nsp] IPv6 on MSFC2

[Church, Chuck]

Thanks Hank.  In my particular case, I was using the right command, but
it wasn't working.  Was giving a "not-supported" type message.  When I
reset the flexwan, it started working fine.  Some kind of software bug,
maybe.  Will definitely keep that list nearby.  Another one that the
Cisco guys mentioned was:

PSRB-U00-OR-01#show controllers cwan 2 0 ?
  align         Show recorded alignment data
  logging       Show logging information
  proc          Active process statistics
  tech-support  Show system information for tech-support

That one seems helpful, as it's possible to grab some flexwan stuff
without consoling into it.

Thanks,

Chuck

Chuck,

In addition you might want to cut and paste the following that was
