For each DSCP value, you can configure the queue to which you want to map the DSCP 
value. The selected queue (0 through 7) becomes the traffic class for a port or LAG. The 
priority of the queue goes from low (0) to high

 

(7).

By default, the DSCP values are mapped to the following queues:

Class Selector (CS) PHB values:

CS 0 to queue 2

CS 1 to queue 0

CS 2 to queue 1

CS 3 to queue 3

CS 4 to queue 4

CS 5 to queue 5

CS 6 to queue 6

CS 7 to queue 7

Assured Forwarding (AF) PHB values:

AF11 through AF13 to queue 0

AF21 through AF23 to queue 1

AF31 through AF33 to queue 3

AF41 through AF43 to queue 4

Expedited Forwarding (EF) PHB value:

EF to queue 5

Other DSCP values (Local/Experimental Use):

1 through 7 to queue 2

9, 11, 13, and 15 to queue 0

17, 19, 21, and 23 to queue 1

25, 27, 29, and 31 to queue 3

33, 35, 37, and 39 to queue 4

41 through 45 and 47 to queue 5

49 through 55 to queue 6

57 through 63 to queue 7

The following are some guidelines for the per-hop behavior (PHB) groups:

Class Selector (CS) PHB. This group consists of CS0 through CS7 and is based on the 
IP precedence in the Type of Service (ToS) byte of the IP header to provide backward 
compatibility with IP precedence.

Assured Forwarding (AF) PHB. This group defines four main levels to sort and 

manipulate some flows within the network to guarantee delivery as long as congestion
