This chapter describes the Cisco NX-OS quality of service (QoS) commands that begin with Q.
To configure tail drop by setting queue limits on ingress queues, use the queue-limit command. To remove a queue limit, use the no form of this command.
queue-limit queue-size bytes 40G queue-size bytes
no queue-limit queue-size bytes 40G queue-size bytes
Policy map type network-qos class configuration.

This command was modified. The command was extended to set the queue limit size for 40G interfaces also. |

You can use this command to specify or modify the maximum number of packets the queue can hold for a class policy configured in a policy map. The system drops packets that exceed the configured queue-size threshold.
The same queue-limit value applies to both 10G port and 40G port. This queue limit applies to unicast traffic drop class traffic only. For example, if you set the queue-limit for 20480 bytes, then this command will configure the queue-limit for both 10G and 40G ports as 20480 bytes.
You can use this command only for network-qos class maps that do not have “pause” configured.
This example shows how to assign a queue limit to a policy map network-qos class:
