| Class of Service
Interfaces |
|
Interface Name
(See the interface naming conventions in the J-series Services Router Basic LAN and WAN Access Configuration Guide.)
|
Lists the names of physical and logical interfaces configured on the
system.
Allows you to edit CoS component assignments to physical and logical
interfaces.
|
To edit an interface's CoS assignments, click the interface.
|
|
Class of Service Overview
|
Displays the CoS components assigned to a particular interface—for
example, information about DSCP classifiers, EXP classifiers, or DSCP rewrite
rules.
|
None.
|
|
Add
|
Allows you to add a CoS service to a physical interface.
|
To add a CoS service to a physical interface, click Add.
|
|
Delete
|
Removes CoS services assigned to a specific interface.
|
To remove CoS services assigned to a specific interface, locate the
interface name, click the check box next to it, and click Delete.
|
| 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.
Note: For 4-port Fast Ethernet ePIMs, if you apply a CoS scheduler map on
outgoing (egress) traffic, the router does not divide the bandwidth appropriately
among the CoS queues. As a workaround configure enforced CoS shaping on the
ports.
|
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 all logical interfaces configured
on a physical interface at the same time.
|
To specify an interface for CoS assignment, type its 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 (*).
|
|
Scheduler Map
|
Specifies a predefined scheduler map for this interface.
Note: You can configure either a scheduler map or a virtual channel group
on a logical interface, not both.
|
To assign a scheduler map to the interface, select it from the list.
|
|
Forwarding Class
|
Assigns a predefined forwarding class to incoming packets on a logical
interface.
|
To assign a forwarding class to the interface, select it.
|
|
Virtual Channel Group
|
Applies a virtual channel group to a logical interface.
Applying a virtual channel group creates a set of eight queues for each
virtual channel in the group.
Note: You can configure either a scheduler map or a virtual channel group
on a logical interface, not both.
|
To specify a virtual channel group for the interface, select it from
the list.
|
|
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 apply rewrite rule configurations to a logical interface.
Rewrite rules rewrite the CoS values in an outgoing packet based on
forwarding class and loss priority.
You can choose to apply your own rewrite rule or a default one. The
default rewrite assignments are based on the default bit definitions of DSCP,
DSCP IPv6, MPLS EXP, and IP precedence.
|
To apply a rewrite rule configuration to the interface, select a rule
for each CoS value type used on the interface.
