throughput / latency / balance \[view] global configuration view \[notes] to enhance the user friendliness of asternos in roce scenarios, we support "easy roce" configuration and management there are two modes in roce scenario "lossless ethernet" and "lossy ethernet" in lossless mode, the system will automatically generate lossless configuration templates, with default dscp mapping, enabling pfc and ecn for queue 3 and 4, and setting strict priority scheduling for queue 6 and 7 at the same time, it is supported for you to enter the corresponding configuration view to modify the parameters run
