I believe you then have to play around with the frame distribution
settings in the Cat to maybe get what you're after. I only see the
options in CatOS, I didn't dig too deep to find in in the Native IOS
command set.
From Cisco:
When configurable, EtherChannel frame distribution can use MAC
addresses, IP addresses, and Layer 4 port numbers. You can specify
either source or destination address or both source and destination
addresses and Layer 4 port numbers. The mode you select applies to all
EtherChannels configured on the switch. Use the option that provides the
greatest variety in your configuration. For example, if the traffic on a
channel is going to a single MAC address only, using source addresses or
IP addresses or Layer 4 port numbers as the basis for frame distribution
may provide better frame distribution than selecting MAC addresses as
the basis.
I think that's about as good as it gets...

I'm not sure. Try calling the Internet's head office -- it's in the book.
