Forwarding Classes and PLP Levels
A packet’s forwarding class assignment and PLP level are used by the Junos OS
class of service (CoS) features. The Junos OS CoS features include a set of mechanisms
that you can use to provide differentiated services when best-effort traffic delivery is
insufficient. For router (and switch) interfaces that carry IPv4, IPv6, and MPLS traffic,
you can configure CoS features to take in a single flow of traffic entering at the edge of
your network and provide different levels of service across the network—internal
forwarding and scheduling (queuing) for output—based on the forwarding class
assignments and PLP levels of the individual packets.
NOTE: Forwarding-class or loss-priority assignments performed by a policer
or a stateless firewall filter override any such assignments performed on the
ingress by the CoS default IP precedence classification at all logical interfaces
or by any configured behavior aggregate (BA) classifier that is explicitly
mapped to a logical interface.
