HP3800 Metering drop policy

lyndon160 — Thu, 14 Apr 2016 10:06:27 GMT

Hi,

Using the HP3800 switch with a RYU controller, I apply a meter to a flow of 20mbps. The meter installs correctly and does rate-limit the flow. However the observed throughput is something like 8mbps (this was tested using iperf). - note that with other non-HP switches the obersevred throughput much closer to the meter at around 19mbps.

So I was wondering if anyone could tell me more about the specifics of the discard policy on the HP3800?

Thanks,

Lyndon

Hey Lyndon!
I’m also going through a similar issue like yours to some extent but i really don’t have any idea about the discard policy on the HP3800. I request you to please share the information if you got your answer. As it will be helpful for me also.

Thanks

Of course, I am planning on doing some more rigorous tests with this next week. If I find anything useful I will share it here :)
