It's load balanced via a hash over the specified fields. So if you only got two flows there's a 50% chance that they will end up on the same link. Your real traffic will have a lot more flows so it will even out. Paul 2018-06-21 21:48 GMT+02:00 Jacob DeGlopper : > OK, that was a search-and-repla

OK, that was a search-and-replace error in the original quote. This is still something with your layer 3/4 load balancing. iperf2 does not support setting the source port, but iperf3 does - that might be worth a try.     -- jacob On 06/21/2018 03:37 PM, mj wrote: Hi Jacob, Thanks for you

Consider trying some variation in source and destination IP addresses and port numbers - unless you force it, iperf3 at least tends to pick only even port numbers for the ephemeral source port, which leads to all traffic being balanced to one link. In your example, where you see one link being

Hi, I'm trying out bonding to improve ceph performance on our cluster. (currently in a test setup, using 1G NICs, instead of 10G) Setup like this on the ProCurve 5412 chassis: Procurve chassis(config)# show trunk Load Balancing Method: L4-based Port | Name Type
