Creating and configuring an FR class
An FR class specifies a set of QoS parameters for traffic control and regulation on FR PVCs. To provide QoS on a PVC, create an FR class, set QoS parameters such as FRTS settings in the class, and map the class to the PVC.
You can map an FR class to PVCs by mapping it to FR interfaces or DLCIs.
The FR class mapped to an FR interface takes effect on all PVCs on the interface.
The FR class mapped to a DLCI takes effect only on the PVC identified by the DLCI.
An QoS-capable FR PVC selects an FR class in the following order:
The FR class mapped to the DLCI
The FR class mapped to the FR interface
To configure and create an FR class:
Step | Command | Remarks | |
|---|---|---|---|
1. Enter system view. | system-view | N/A | |
2. Create an FR class and enter FR class view. | fr class class-name | By default, no FR class is created. | |
3. Return to system view. | quit | N/A | |
4. Map the FR class to an FR interface or DLCI. | (Method 1) Map the FR class to an FR interface. |
| Use either method or both methods. By default, no FR class is mapped to any FR interface or DLCI. |
(Method 2) Map the FR class to an DLCI. |

In FR class view, you can configure QoS parameters for QoS services such as FRTS, FR traffic policing, FR congestion management, and FR queuing. For more information about the parameter configurations, see the subsequent sections.
