I am finding it very hard to understand the Qos architecture of Nexus 7k (and 5K). I know about MQC and all that stuff, but unable to fully understand the architecture of qos in Nexus. I am looking for a good document that explains how the packets go through different queues, what can and cannot be done at ingress/egress...different stages of buffer...what is done at stage1 and stage2...just the flow path of the packet from ingress to egress.
Some documentation say that all qos processing is done at ingress (even egress queueing...it that right?) card...how is that possible? So, you see...I am not getting the full picture of how the whole qos thing works on Nexus.
I know all the basic stuff (15 years of networking experience), but not the complete big picture of qos architecture. I have searched on Internet for many hours for this, but still don't find a good document on this.
I would appreciate if anyone can point me to such documents that will explain the concepts (not the config guide or examples guide) of qos in Nexus. Once I understand that, understanding the config guide and sample configs will be very easy.
