[c-nsp] IRB and channel-group help needed

[Michael Ulitskiy]

I have it working exactly this way. my IOS is 12.1(26)E7
the only special thing I remember about it is that if you want to spread port-channels across the
different cards then those cards must be the same (or compatible). For example you can't have port-channel
over ports on GE card and Enhanced GE card or between card with ACL daughter card and without it.

I can take the subinterfaces off temporarily and set up the channel-group, but it I try and re-add the subinterfaces, I can't do that. Is this something that is possible? If so, what am I missing?
