Traffic policing actions include re-assigning service group based on DSCP +
conform-level to service map, re-assigning traffic’s 802.1p precedence based on TC +

maps using commands listed in the following table.

CoS map in conform-level view.
local-precedence CoS-value0 CoS-value1
CoS-value2 CoS-value3 CoS-value4
