GEC Bundle traffic.

We have just configured a GEC bundle between two interfaces on a Cat6509 and 2 x Cat 3550 over a 1GB Link.

So we have

Cat 6509 --- Cat 3550

g9/1 --- g0/1

g9/2 --- g0/2

And I was expecting the flow of traffic between the links to be divided between the 2 links but the attached is what I get.

How can I get it to be more evenly distributed?

Thanks

Re: GEC Bundle traffic.

Traffic in an EtherChannel is distributed across the individual bundled links in a deterministic fashion. However, the load is not necessarily balanced equally across all the links. Instead, frames are forwarded on a specific link as a result of a hashing

algorithm. The algorithm can use source IP address, destination IP address, or a combination of source and destination IP addresses, source and destination MAC addresses,or TCP/UDP numbers.To set the load-distribution method among the ports in the bundle, use the port-channel load-balance command.
