Figure 44-5 Traffic marking Procedure Flowchart
Restrictions for Marking Network Traffic
The following restrictions apply to packet marking actions:
• QoS-group can be marked only in the input direction and can only support unconditional explicit
marking.
• Only explicit marking is supported for policer-based marking.
Multi-attribute Marking Support
The supervisor engine can mark more than one QoS attribute of a packet matching a class of traffic. For
example, DSCP, CoS, and QoS-group can all be set together, using either explicit or tablemap-based
marking.
