I understand that in ACI they are 3 QOS Class defined : LEVEL1, LEVEL2 and LEVEL3.
Each of these 3 AOS Class has some configuration parameters that can be customized but i did'nt find any explnation about the meaning of these parameters (even in the Help from ACI screen).
I attached the relative APIC pannel in this question also.
- Bandwidth allocated (in % ) : what does it mean? does it mean that in case of congestion of the link the EPG flow on which the corresponding LEVELx is configured will be reduced to 20% max?
- Scheduling algorithm : Weigted Round Robin (WRR) or Strict Priority , what does it mean? , does WRR mean that the EPG's bytes (or packets?) will be dispatched on the Queues (what Queues? the Queues affected to each of the Leaf 's ports?) ? How can i know the number of the Queues? . About Strict Priority, does it mean that only 1 Queue will be used but the related EPG's bytes (packets?) will be urgently dispatched to that unique Queue ? and what happens when a congestion occurs on the link in regards of that Strict Priority Queue?
- Congestion algorithm : what Tail Drop means ? Tail Drop must be used together with WRR used ?
