When a trunk on the BIG-IP 5000 or 10000 platforms has an odd number of members, the traffic distribution to those interfaces will be unbalanced. Some interfaces will see more traffic than others.
Uneven traffic distribution.
This can occur for two reasons: -- Purposefully configuring an odd number of members. -- A port goes down in a trunk that has an even number of members.
None.
This release fixes uneven egress trunk distribution on the BIG-IP 5000 or 10000 platforms when there is an odd number of ports.
