Summary |
|
DSCP
|
Allows you to define classifiers for DSCP IPv4 values.
|
To define a classifier for a DSCP code point value, click DSCP.
|
|
DSCP IPv6
|
Allows you to define classifiers for DSCP IPv6 values.
|
To define a classifier for a DSCP IPv6 value, click DSCP IPv6.
|
|
MPLS EXP
|
Allows you to define classifiers for MPLS experimental (EXP)
bits.
|
To define a classifier for a set of MPLS EXP bits, click MPLS EXP.
|
|
IPv4 Precedence
|
Allows you to define classifiers for IPv4 precedence values.
|
To define a classifier for an IP precedence value, click IPv4 Precedence.
|
|
Classifier Name
|
Displays the names of classifiers.
Allows you to edit a specific classifier.
|
To edit a classifier, click its name.
|
|
Incoming Code Point (Alias)
|
Displays CoS values and aliases to which forwarding class and
loss priority are mapped.
|
None.
|
|
Classify to Forwarding Class
|
Displays forwarding classes that are assigned to specific CoS
values and aliases of a classifier.
|
None.
|
|
Classify to Loss Priority
|
Displays loss priorities that are assigned to specific CoS values
and aliases of a classifier.
|
None.
|
|
Add
|
Opens a page that allows you to define classifiers.
|
To add a classifier, click Add.
|
|
Delete
|
Deletes a specified classifier.
|
To delete a classifier, locate the classifier, select the check
box next to it, and click Delete.

|
Classifier Name
|
Specifies the name for a classifier.
|
To name a classifier, type the name—for example, ba-classifier.
|
|
Classifier Code Point Mapping
|
Sets the forwarding classes and the packet loss priorities (PLPs)
for specific CoS values and aliases.
|
None.
|
|
Incoming Code Point
|
Specifies the CoS value in bits and the alias of a classifier
for incoming packets.
|
To specify a CoS value and alias, either select preconfigured
ones from the list or type new ones.
For information about forwarding classes and aliases assigned
to well-known DSCPs, see the JUNOS Software with Enhanced Services Interfaces and Routing Configuration Guide.
|
|
Forwarding Class
|
Assigns the forwarding class to the specified CoS value and
alias.
|
To assign a forwarding class, select either one of following
default forwarding classes, or one that you have configured:
-
best-effort—Provides no special
CoS handling of packets. Typically, RED drop profile is aggressive
and no loss priority is defined.
-
expedited-forwarding—Provides
low loss, low delay, low jitter, assured bandwidth, and end-to-end
service. Packets can be forwarded out of sequence or dropped.
-
assured-forwarding—Provides
high assurance for packets within specified service profile. Excess
packets are dropped.
-
network-control—Packets can
be delayed but not dropped.
|
|
Loss Priority
|
Assigns a loss priority to the specified CoS value and alias.
|
To assign a loss priority, select one of the following:
-
low—Packet has a low loss priority.
-
high—Packet has a high loss
priority.
-
medium-low—Packet has a medium-low
loss priority.
-
medium-high–Packet has a medium-high
loss priority.
|
|
Add
|
Assigns a forwarding class and loss priority to the specified
CoS value and alias.
A classifier examines the incoming packet's header for the specified
CoS value and alias and assigns it the forwarding class and loss priority
that you have defined.
|
To assign a forwarding class and loss priority to a specific
CoS value and alias, click Add.
|
|
Delete
|
Removes the forwarding class and loss priority assignment from
the classifier.
|
To remove the forwarding class and loss priority assignment,
select it and click Delete.
