The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco NX-OS system management commands that begin with H.
To configure the proxy-queue drain rate settings, use the hardware pq-drain command in global confiiguration mode. To disable proxy-queue drain settings, use the no form of this command.
hardware pq-drain 10g 10g-drain-rate 40g 40g-drain-rate
Proxy Queue drain rate for the 10 G interface. The range is from 1 Mbps to 20000 Mbps. |

Proxy Queue drain rate for the 10 G interface. The range is from 1 Mbps to 80000 Mbps. |

Note This command is applicable to only Cisco Nexus 6000 switches.
When the proxy queue reaches a threshold that indicates congestion, Explicit Congestion Notification (ECN) marking is performed so that the receiver of the packet echoes the congestion indication to the sender. The proxy-queue drain rate is configured to ensure that during congestion at egress ports only a certain amount of packets are drained.
This example shows how to configure proxy-queue settings to drain 9900 Mbps of traffic from 10 Gigabait interfaces and 39900 Mpbs of traffic from 40 Gigabit interfaces:

To configure Explicit Congestion Notification (ECN) for a Quality of Service (QoS) group, use the hardware random-detect command in global configuration mode. To disable ECN, use the no form of this command.
hardware random-detect min-thresh 10g 10g-min-theshold 40g 40g-min-threshold max-thresh 10g 10g-max-threshold 40g 40g-max-threshold ecn qos-group group-number

Note This command is applicable to only Cisco Nexus 6000 switches.
To implement Weighted Random Early Detection (WRED) Explicit Congestion Notification (ECN) on proxy queues you use the hardware random-detect command to configure minimum and maximum threshold values per QoS group. Then you use the hardware pq-drain command to configure the proxy-queue drain rate.
This example shows how to enable ECN threshold values for the class-default QoS group:
