Configuring QoS Functions
The DSCPs associated with a PHB are assigned to the appropriate QoS profile using the
config diffserv examination code-point command. For example, the following
command sets up the mapping for the EF PHB:
config diffserv examination code-point 46 qosprofile qp8 ports 2:1-2:2
Additional configuration steps for SONET ports in this example are as follows:
• Enable RED for all PHBs except the EF PHB. For example:
enable red ports 2:1-2:2
disable red ports 2:1-2:2 queue 8
• Configure a high drop-probability of 20% on the SONET ports. For example:
config red high-drop-probability 20 ports 2:1-2:2
• Enable examination of DiffServ information. For example:
enable diffserv examination ports 2:1-2:2
• Configure the default PHB. For example:
config diffserv examination code-point 0 qosprofile qp1 ports 2:1-2:2
• Configure the Class Selectors. For example:
config diffserv examination code-point 8 qosprofile qp2
ports 2:1-2:2 high-drop-probability
config diffserv examination code-point 16 qosprofile qp2
ports 2:1-2:2 high-drop-probability
config diffserv examination code-point 24 qosprofile qp2
ports 2:1-2:2 high-drop-probability
config diffserv examination code-point 32 qosprofile qp2
ports 2:1-2:2 low-drop-probability
config diffserv examination code-point 40 qosprofile qp2
ports 2:1-2:2 low-drop-probability
config diffserv examination code-point 48 qosprofile qp3
ports 2:1-2:2 high-drop-probability
config diffserv examination code-point 56 qosprofile qp3
ports 2:1-2:2 low-drop-probability
• Configure the drop-probability for the DSCPs assigned to AF1 through AF4.
For example, for AF1 (qp4):
c
onfig diffserv examination code-point 10 qosprofile qp4
ports 2:1-2:2 low-drop-probability
config diffserv examination code-point 12 qosprofile qp4
ports 2:1-2:2 high-drop-probability
