Procedure 14-5: Provision QoS differentiated services
Differentiated services components
QoS differentiated services are configured in stages by provisioning the following differentiated services (DiffServ) components:
-
Class: The DiffServ class defines the packet filtering criteria. A match criteria is defined for each class. Packet processing begins when the switch tests the match criteria for a packet.
-
Policy: The DiffServ policy attributes define the way the switch processes packets. Policy attributes may be defined on a per-class instance basis. The switch applies these policy attributes when it finds a class match. The switch applies a policy to a packet when it finds a class match within that policy.
-
Service: The DiffServ service commands are used to assign a provisioned class/policy association to an interface in the incoming direction. The service commands attach a defined policy to a directional interface. You can assign only one policy at any one time to an interface in the inbound direction. DiffServ is not used in the outbound direction.

Step
1 |
Log in to the VLNC4x circuit pack being provisioned. |
2 |
Create a new or modify an existing DiffServ class map and define the match criteria for the class. Reference: Procedure 14-5.1: Provision differentiated services class |
3 |
Create a new or modify an existing DiffServ policy. Reference: Procedure 14-5.2: Provision differentiated services policy |
4 |
Assign the required provisioned DiffServ class to the required provisioned DiffServ policy. Reference: Procedure 14-5.3: Assign class to policy |
5 |
Assign the required class/policy association to the required Ethernet interface to form a service. Reference: Procedure 14-5.4: Assign class/policy to incoming Ethernet interface End of steps |
