Using BA Classifiers to Set PLP
Behavior aggregate (BA) classifiers take action on incoming packets. When TCM is enabled, Juniper Networks M320 Multiservice Edge Routers and T Series Core Routers support four classifier PLP designations: low, medium-low, medium-high, and high. To configure the PLP for a classifier, include the following statements at the [edit class-of-service] hierarchy level:
The inputs for a classifier are the CoS values. The outputs for a classifier are the forwarding class and the loss priority (PLP). A classifier sets the forwarding class and the PLP for each packet entering the interface with a specific set of CoS values.
For example, in the following configuration, the assured-forwarding forwarding class and medium-low PLP are assigned to all packets entering the interface with the 101110 CoS values:
To use this classifier, you must configure the settings for the assured-forwarding forwarding class at the [edit class-of-service forwarding-classes queue queue-number assured-forwarding] hierarchy level. For more information, see Overview of Forwarding Classes.
