Thanks for those hints. So it is best to think of how the flows are
initiated? In my example should I think of the hosts initiating the flow
and configure SW1? But in that case should I consider the return traffic
back from the Server via SW2 and use dst-mac or won't that matter? Is it
only important how the flow was first load-balanced with a unique mac-mac or
mac-ip or ip-ip mapping and trunk assignment?
How about mixing 3550's and 3560's on each side?
Rgds,
Rich
