I read some documentation way back that said you could but that it wasn't 
recommended. Because port channeling doesn't really do load balancing - it 
just looks at the least significant bit(s) in the source/destination MAC 
address (depending on configuration) to choose the physical port, you could 
end up with very odd performance issues as lots of traffic is shunted down 
the 100Mb/s link. To put it another way, port channeling doesn't look at 
interface speeds before making any decisions.

The same as far as I know... And as far as your previous question, while I 
haven't done it I can't think of any reason you can't port channel between 
a SFP port and a normal UTP port.

HTH.
