That sounds right to me - I havent looked it up, but I would imagine in
scenario 1 or 2 you would want src-dst-mac or src-dst-ip, as I assume
this means a unique ip or mac pair (src and dest pair). So if server is
talking to 4 hosts, and you use src-dst-* then you'll get 4 combinations
and thus load balancing.

Subject: Re: Etherchannel load balancing
Well,
I think this is more related with what kind of traffic is running over
the port-channel as I have undertood it.
Imagine those two scenarios;
1) You have a port-channel (four interfaces in the bundle) going to a
server and this server is talking to four hosts. If you do src-mac or
src-ip you will use only one physical interface in the buddle since your
traffic is coming from only one device
2) You have a vlan with four hosts talking to one server via a
port-channel (four interfaces in the bundle). If you use dst-mac or
dst-ip you will again use only one physical interface in the buddle
since all the traffic is going to the same host.
The example is a bit exagerated but I think you get the idea, it's
really depend on your traffic pattern.
Any more comments?
