classifiers (CoS)


Hierarchy Level


Configure a user-defined behavior aggregate (BA) classifier.


  • classifier-name—User-defined name for the classifier.

  • import (default | user-defined)—Specify the template to use to map any code points not explicitly mapped in this configuration. For example, if the classifier is of type dscp and you specify import default, code points you do not map in your configuration will use the predefined DSCP default mapping; if you specify import mymap, for example, code points not mapped in the forwarding-class configuration would use the mappings in a user-defined classifier named mymap.

  • forwarding-class class-name—Specify the name of the forwarding class. You can use the default forwarding class names or define new ones.

  • loss-priority level—Specify a loss priority for this forwarding class: high, low, medium-high, medium-low.

  • code-points (alias | bits)—Specify a code-point alias or the code points that map to this forwarding class.
