SW(config-if)#mls qos cos ? <0-7> Class of service value between 0 and 7 override Force default COS on all packets COS override可以强制在帧进入时按定义的default COS的值来执行策略,如果是接口的状态是trust,那么如果开启了COS override后,自动关闭接口的trust,直接使用在入口的COS-内部DSCP的map。
mls qos map cos-dscp Defines the ingress CoS-to-DSCP map for trusted interfaces. mls qos map cos-mutation Maps a packet's CoS to a new CoS value. mls qos map dscp-cos Defines an egress DSCP-to-CoS map. mls qos map dscp-mutation Defines a named DSCP mutation map. mls qo...
MLS QOS默认3550上关闭 对于接口的信任状态只能是一种，要么是COS，要么是DSCP，要么是IP优先级，不可重复。当携带有（cos dscp IP precedence）的数据进入交换机后，如果交换机信任这个数据包携带的标签（cos dscp ip precedence）的话，那么会映射到一个内部的DSCP表（也就是cos-内部dscp， ip precedence-内部...
Not a QoS expert here but I am really trying to study and understand at the moment. We have added a new C9200L to our office and I am stuck with configuring the MLS part.. Below is the existing config in the C2960XR ! mls qos map cos-dscp 0 8 16 24 32 46 48 56mls qos sr...

If the port has "mls qos trust cos" then the switch will use the CoS marking in the packet. But because switches always use an internal DSCP marking the switch needs to derive a DSCP value from the CoS value. This is what the CoS-to-DSCP map is for. The DSCP-to-CoS map ...
