Beginner Basics • Re: CRS317 - cannot get traffic to Queue

For simple queues to work you have to disable HW offload on upstream interface (sfp-sfpplus16). But beware that this will severely load CRS's main CPU and will limit max throughput via that interface possibly to less than 1Gbps depending on traffic patterns (check test results of your device, you're looking at bridging instead of switching).

The other, better, way of doing it is to use switch QoS functionality instead. Check manual, something like
Code:
/interface ethernet switch portset sfp-sfpplus16 ingress-rate=3G egress-rate=3G
and ditch the queue setup.

BTW, do you have to limit ingress (Rx) rate? Ideally the other end should be doing this part ...
I am not getting great results with the ingress=rate setup .. the egress seems to work but if I want to gets lets say 150M on ingress I have to set it to like 700M. and I dont know.. something just doesnt make me trust that setup.. ive read that there are ACLs you can do to set that up, but I havent been able to find an example.. and im just locking myself out my switch over and over (Im using safe mode) but just can not get it to work at all.

Thank you
