[c-nsp] 3750 etherchannel only using 1 port

[Paul]

I did the test etherchannel of course and it's working properly, but 
since I am using the cef load balancing (two 0.0.0.0 routes with the 
same cost)  and it's going out two port channels the algorithm for that 
must be exactly the same as the one for the etherchannel, which explains 
why on etherchannel #1 the packets are going out port #1, and on 
etherchannel #2 the packets are going out port #2..   This is a very 
interesting phenomenon :) 

Now I just have to figure out what to do about it..... I Completely 
would not have thought that it would operate like this but I suppose it 
makes sense..  Grr :>
Any ideas?
