Clueless Network Prob

[Matthew Carpenter]

I could be wrong, but I'm pretty sure you can't.  If you have two adaptors on one subnet, which will it use for origination?  If you do subinterfaces on the SAME adaptor, at least the interface has a real address which it can use to originate and open connections.  If I'm incorrect, please let me know... not that I'm sure why you would WANT two adaptors on one subnet, except to port-channel, and that's a different story altogether.
