Configuring priority marking
Priority marking sets the priority fields or flag bits of packets to modify the priority of packets. For example,
you can use priority marking to set IP precedence or DSCP for a traffic class of IP packets to control the
forwarding of these packets.
To configure priority marking, you can associate a traffic class with a traffic behavior configured with the
priority marking action to set the priority fields or flag bits of the traffic class of packets.
Priority marking can be used together with priority mapping. For more information, see "Configuring
pr
i
ority mapping."
