I agree with you. Of course, assuming this is a L2 EtherChannel (no L3
routing involved, all hosts in the same VLAN).
See bellow the results i had. Since we have an odd number of clients (3),
the load will be distributed in a 2:1 ratio.

Subject: Etherchannel Load Balancing
Hi Group,
Below is the scenario
PC1 -------
PC2 ------- SW1 ----------- Ether channel ---------- SW2 --------------
Server
PC2 -------
Multiple PC's are connected to SW1 which has a ether channel to SW2, where
the server is connected. If the PC's are accessing the server. What is the
best load balancing method.
What I think is, it can be either of the two options listed below
if 3550/3560
Option 1
On SW1 - src-mac
On SW2 - dst-mac
or
if 3560
Option 2
On SW1 - src-ip
On SW2 - dst-ip
Please correct me if I'm wrong
Regards
