Priority marking overview
NOTE:
Priority marking can be used together with priority mapping. For more information, see the chapter
"Priority mapping configuration."
Priority marking sets the priority fields or flag bits of packets to modify the priority of traffic. For example,
priority marking allows you to set IP precedence or DSCP for a class of IP traffic to change its transmission
priority in the network.
To configure priority marking, 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.
