show class-of-service classifier

Syntax

show class-of-service classifier<name name><type dscp | type dscp-ipv6 | type exp | type ieee-802.1 | type inet-precedence>

Release Information

Command introduced before Junos OS Release 7.4.

Command introduced in Junos OS Release 9.0 for EX Series switches.

Description

For each class-of-service (CoS) classifier, display the mapping of code point value to forwarding class and loss priority.

Options

none: Display all classifiers.
name name: (Optional) Display named classifier.
type dscp: (Optional) Display all classifiers of the Differentiated Services code point (DSCP) type.
type dscp-ipv6: (Optional) Display all classifiers of the DSCP for IPv6 type.
type exp: (Optional) Display all classifiers of the MPLS experimental (EXP) type.
type ieee-802.1: (Optional) Display all classifiers of the ieee-802.1 type.
type inet-precedence: (Optional) Display all classifiers of the inet-precedence type.

Output Fields

Table 1 describes the output fields for the show class-of-service classifier command. Output fields are listed in the approximate order in which they appear.

Table 1: show class-of-service classifier Output Fields

Field Name	Field Description
Classifier	Name of the classifier.
Code point type	Type of the classifier: exp (not on EX Series switch), dscp, dscp-ipv6 (not on EX Series switch), ieee-802.1, or inet-precedence.
Index	Internal index of the classifier.
Code point	Code point value used for classification
Forwarding class	Classification of a packet affecting the forwarding, scheduling, and marking policies applied as the packet transits the router.
Loss priority	Loss priority value used for classification. For most platforms, the value is high or low. For some platforms, the value is high, medium-high, medium-low, or low.
