JUNI-RT-000740 - The Juniper PE router must be configured to enforce a Quality-of-Service (QoS) policy in accordance with the QoS GIG Technical Profile - class-of-service

Information

Different applications have unique requirements and toleration levels for delay, jitter, bandwidth, packet loss, and availability. To manage the multitude of applications and services, a network requires a QoS framework to differentiate traffic and provide a method to manage network congestion. The Differentiated Services Model (DiffServ) is based on per-hop behavior by categorizing traffic into different classes and enabling each node to enforce a forwarding treatment to each packet as dictated by a policy.

Packet markings such as IP Precedence and its successor, Differentiated Services Code Points (DSCP), were defined along with specific per-hop behaviors for key traffic types to enable a scalable QoS solution. DiffServ QoS categorizes network traffic, prioritizes it according to its relative importance, and provides priority treatment based on the classification. It is imperative that end-to-end QoS is implemented within the IP core network to provide preferred treatment for mission-critical applications.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Configure all interfaces to use a configured or the default BA classifier as shown in the example below:

[edit class-of-service interfaces]
set ge-0/0/1 unit 0 classifiers dscp default
set ge-0/1/0 unit 0 classifiers dscp default
set ge-1/0/1 unit 0 classifiers dscp default
set ge-1/1/0 unit 0 classifiers dscp default
