Transmit queues are logical partitions of an Ethernet port’s egress bandwidth. Data streams are assigned to queues based on their traffic class, then sent as scheduled by port and transmit settings. Sand platform switches have eight queues, 0 through 7, and all queues are exposed through the CLI. However, queue 7 is not user-configurable. Queue 7 is always mapped to traffic class 7, which is reserved for control plane traffic. This feature allows tx-queue 7 to be configurable. As of 4.33.0F, a limited set of features are configurable on tx-queue 7.

Latency and drop information help determine if there is a loss in a particular flow and where the loss occurred. A Service Node action configured as a DMF-managed service that, given two separate taps or spans in the production network, can measure the latency of a flow traversing through these two points. It can also detect packet drops between two points in the network if the packet only appears on one point within a specified time frame, currently set to 100ms.

The low latency tx-queue scheduler profile feature aims to provide an alternative operating mode for the queue that is fine-tuned for reduced latency. This involves a tradeoff between achieving lower latency and being able to sustain full throughput over a large number of flows.

This feature allows setting the desired maximum VOQ latency. Drop probabilities are adjusted in hardware to meet this limit.
