  • Policy map support (PTX10002-36QDD)—Starting in Junos OS Evolved Release 23.4R2-S1, PTX10002-36QDD routers support policy maps, which enable you to assign rewrite rules on a per-customer basis. The policy map makes it possible to use any packet field to identify a given flow and specify a rewrite value for that flow. PTX10002-36QDD routers support the following types of packet marking: INET-Precedence, DSCP, IEEE802.1p, and IEEE802.1ad.

    You can define a policy-map at the [edit class-of-service] hierarchy level. You enable policy-map-marking at the egress interface at the [edit class-of-service interfaces interface-name unit unit-number] hierarchy level.
