Assigning CoS Components to Interfaces (J-Web Procedure)
After you have defined CoS components, you
must assign them to logical or physical interfaces. The CoS Configuration
pages allow 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:
- In the J-Web interface, select Configure>Class
of Service>Interface Association.
- Enter information into these pages, as described
in Table 1.
- Click one:
- Click OK to apply changes to the configuration.
- Click Cancel to cancel without saving changes.

Field
|
Function
|
Your Action
|
Add CoS Service to a Physical Interface/Edit
CoS Physical Interface
|
Physical Interface Name
|
Specifies the name of a physical interface. Allows you
to assign CoS components to a set of interfaces at the same time.
|
To specify an interface for CoS assignment, type its
name in the Physical Interface Name box.
To specify a set of interfaces for CoS assignment, use the wildcard
character (*)—for example, ge-0/*/0.
|
Scheduler Map
|
Specifies a predefined scheduler map for the physical
interface.
A scheduler map enables the physical interface to have more
than one set of output queues.
|
To specify a map for an interface, select it from the
Scheduler Map list.
|
Add
|
Allows you to add a CoS service to a logical interface
on a specified physical interface.
|
To add a CoS Service to a logical interface, click Add.
|
Add CoS Service to a Logical Interface
Unit/Edit CoS Logical Interface Unit
|
Logical Interface Unit Name
|
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.
|
To specify an interface for CoS assignment, type the
interface name in the Logical Interface Unit Name box.
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 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.
