JN0-664 Exam - Question 12


A packet is received on an interface configured with transmission scheduling. One of the configured queues is exceeding the allocated bandwidth.

In this scenario, which two actions will be taken by default on a Junos device? (Choose two.)

Show Answer
Correct Answer: ABD

On a Junos device configured with transmission scheduling, if a queue exceeds its allocated bandwidth, it will be considered to have negative bandwidth credit. In addition, any excess traffic will use bandwidth available from other queues if there is any excess capacity. This ensures efficient utilization of available bandwidth across all queues.

If a queue exceeds its allocated bandwidth, it is considered to have negative bandwidth credit and its excess traffic will be discarded by default.

By default, each queue can exceed the assigned bandwidth if additional bandwidth is available from other queues. When a forwarding class does not fully use the allocated transmission bandwidth, the remaining bandwidth can be used by other forwarding classes if they receive a larger amount of offered load than the bandwidth allocated. A queue receiving traffic within its bandwidth configuration is considered to have positive bandwidth credit, and a queue receiving traffic in excess of its bandwidth allocation is considered to have negative bandwidth credit. https://www.juniper.net/documentation/us/en/software/junos/cos-security-devices/topics/concept/cos-transmission-scheduling-security-overview.html

De forma predeterminada, cada cola puede exceder el ancho de banda asignado si hay ancho de banda adicional disponible en otras colas. Cuando una clase de reenvío no utiliza completamente el ancho de banda de transmisión asignado, el ancho de banda restante puede ser utilizado por otras clases de reenvío si reciben una cantidad mayor de carga ofrecida que el ancho de banda asignado. Se considera que una cola que recibe tráfico dentro de su configuración de ancho de banda tiene un crédito de ancho de banda positivo, y una cola que recibe tráfico que excede su asignación de ancho de banda tiene un crédito de ancho de banda negativo.
