    Assigning CoS Components to Interfaces (J-Web Procedure)

    After you have defined CoS components on an EX Series switch, you must assign them to logical or physical interfaces. You can use the J-Web interface 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:

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

      Note: After you make changes to the configuration in this page, 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 for details about all commit options.

    2. To configure interface association, select an interface from the list and click Edit. For an EX8200 Virtual Chassis configuration, select the member, FPC, the interface from the list, and click Edit.
    3. Select one:
      • Associate system default scheduler map—Associates the interface with the default scheduler map.
      • Select the scheduler map—Associates the interface with a configured scheduler map. Select the scheduler map from the list.

      Note: On the 40-port SFP+ line card for EX8200 switches, the J-Web interface does not allow you to commit your changes unless you assign the same scheduler map or the default scheduler map to all interfaces in a port group.

    4. Click OK.
    5. To manage a CoS service assignment on a logical interface, click one:
      • Add—Adds a CoS service to a logical interface on a specified physical interface. Enter information as described in Table 1.
      • Edit—Modifies a CoS service assignment to a logical interface. Enter information as described in Table 1.
      • Delete—Deletes the CoS service assignment to a logical interface.

    Table 1: Assigning CoS Components to Logical Interfaces

    Field

    Function

    Your Action

    Unit

    Specifies the name of a logical interface. Allows you to assign CoS components while configuring a logical interface 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 (*).

    Forwarding Class

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

    To assign a forwarding class to an 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 an 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.
