Priority Marking Overview
Priority marking can be used together with priority mapping. For details, see Priority Mapping Table
and Priority Marking Configuration Example .
Priority marking sets the priority fields or flag bits of packets to modify the priority of traffic. For example,
you can use priority marking to set IP precedence or DSCP for a class of IP traffic to change its
transmission priority in the network.
To configure priority marking, you can associate a class with a behavior configured with the priority
marking action to set the priority fields or flag bits of the class of packets.
