JUNI-RT-000750 - The Juniper P router must be configured to enforce a Quality-of-Service (QoS) policy in accordance with the QoS GIG Technical Profile - QoS policy in accordance with the QoS DODIN Technical Profile.

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 P router interfaces and PE core-facing 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
