Table 34: Assigning CoS Components to Logical Interfaces
Your ActionFunctionField
Type the interface name.
To assign CoS to all logical interfaces
configured on this physical interface, type the
wildcard character (*).
Specifies the name of a logical interface. Enables you to
assign CoS components when you configure a logical
interface on a physical interface.
Unit
To assign a forwarding class to an interface,
select the forwarding class.
Assigns a predefined forwarding class to incoming packets
on a logical interface.
Forwarding
Class
To assign a classification map to an interface,
select an appropriate classifier for each CoS
value type used on the interface.
Enables 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.
Classifiers
To assign rewrite rules to the interface, select
the appropriate rewrite rule for each CoS value
type used on the interface.
Enables 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.
NOTE: In EX4300 switches, this option is available only when
you click Edit button in the Configure Interface Association
table.

Defining CoS Forwarding Classes (J-Web Procedure)
NOTE: This topic applies only to the J-Web Application package.
J-Web Application package Release 14.1X53-A2 does not support Class of
Service (CoS) on EX4600 switches.
You can define CoS forwarding classes on an EX Series switch using the J-Web interface.
Assigning a forwarding class to a queue number affects the scheduling and marking of
a packet as it transits a switch.
