Monitoring CoS Classifiers

To display the mapping of incoming CoS value to forwarding class and loss priority, for each classifier, select Monitor > Class of Service > Classifiers in the J-Web interface or enter the following CLI command:

show class-of-service classifier

After you make changes to the configuration in this window, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.

Table 54: Summary of Key CoS Classifier Output Fields

Classifier Name

Name of a classifier.

To display classifier assignments, click the plus sign (+).

CoS Value Type

The classifiers are displayed by type:

  • dscp—All classifiers of the DSCP type.
  • dscp ipv6—All classifiers of the DSCP IPv6 type.
  • exp—All classifiers of the MPLS EXP type.
  • ieee-802.1—All classifiers of the IEEE 802.1 type.
  • inet-precedence—All classifiers of the IP precedence type.


Internal index of the classifier.


Incoming CoS Value

CoS value of the incoming packets, in bits. These values are used for classification.


Assign to Forwarding Class

Forwarding class that the classifier assigns to an incoming packet. This class affects the forwarding and scheduling policies that are applied to the packet as it transits the device.


Assign to Loss Priority

Loss priority value that the classifier assigns to the incoming packet based on its CoS value.
