When configuring QOS:
QOS traffic classifier configuration of GE link at MA5200 is configured 80% of Bandwidth

We find that corresponding traffic configuration matches weight, and the amount of creating CBS is: 240000+160000+240000+80000+80000=800000 is 80% of 1000000. Why?
The software is designed as 80% and 20% bandwidth is reserved for traffic classifier. If reserved bandwidth of manual configuration overpasses 80% of GE interface, the system prompts configuration fails.
