Assigning CoS Components to Interfaces

After you have defined CoS components, you must assign them to logical or physical interfaces. The Configure Interface Association page allows you to assign scheduler maps to physical or logical interfaces and to assign forwarding classes, or classifiers, to logical interfaces.

To assign CoS components to interfaces using the J-Web interface:

  1. Select Configure > Class of Service > Assign To Interface .

    After you make changes to the configuration in this window, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.

  2. To configure an interface association, select an interface from the list and click Edit.
    • Associate system default scheduler map—Select to associate the interface with a default scheduler map.
    • Select the scheduler map—Select to associate the interface with a configured scheduler map. Select the scheduler map from the list.
  3. Click OK.
  4. To manage a CoS service assignment on a logical interface, click one of the following:
    • Add—Adds a CoS service to a logical interface on a specified physical interface. Enter information as described in Table 37.
    • Edit—Edits a CoS service assignment to a logical interface. Enter information as described in Table 37.
    • Delete—Deletes a CoS service assignment to a logical interface.

Table 37: Assigning CoS Components to Logical Interfaces

Field

Function

Your Action

Unit

Specifies the name of a logical interface. Allows you to assign CoS components to a logical interface configured on a physical interface at the same time.

Type the interface name .

To assign CoS services to all logical interfaces configured on this physical interface, type the wildcard character (*).

Schedular map

Allows you to apply schedular map to a logical interface.

To assign a schedular map to the interface, select the schedular map.

Forwarding class

Assigns a predefined forwarding class to incoming packets on a logical interface.

To assign a forwarding class to the interface, select the forwarding class.

Classifiers

Allows you to apply classification maps to a logical interface. Classifiers assign a forwarding class and loss priority to an incoming packet based on its CoS value.

To assign a classification map to the interface, select an appropriate classifier for each CoS value type used on the interface.

Rewrite rules

Allows you to alter the CoS values in outgoing packets to meet the requirements of the targeted peer. A rewrite rule examines the forwarding class and loss priority of a packet and sets its bits to a corresponding value specified in the rule.

To assign rewrite rules to the interface, select the appropriate rewrite rule for each CoS value type used on the interface.
