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

Field Name

Field Description


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.


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.
