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 class of IP packets to
control the forwarding of these packets.
To configure priority marking to set the priority fields or flag bits for a class of packets, perform the
following tasks:
1.
Configure a traffic behavior with a priority marking action.
2.
Associate the traffic class with the traffic behavior.
Priority marking can be used together with priority mapping. For more information, see "
