Priority Marking Configuration Example 

 

Priority marking can be used together with priority mapping. For details, refer to 

 

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.  

Follow these steps to configure priority marking:

Create a class and enter

traffic classifier tcl-name [ operator 
{ and | or } ]
