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.

Configurable Voq Tail Drop Thresholds provides flexibility to change default voq tail drop based on speed of the

Fair Adaptive Dynamic Thresholds (FADT) provides efficient allocation of shared packet buffer resources amongst

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