qos-policy-buffer Create a QoS policy buffer and enter the configuration mode to configure the no-drop queues, ingress buffer size, buffer limit for pausing, and buffer offset limit for resuming. . C9000 Series Syntax Parameters qos-policy-buffer queue queue-num pause no-drop queue buffer-size size pausethreshold threshold-value resume-offset threshold-value shared-threshold-weight size policy-name Name of the QoS policy buffer that is applied to an interface for this setting to be effective in conjunction with the DCB input policy. You can specify the shared buffer threshold limit, the ingress buffer size, buffer limit for pausing the acceptance of packets, and the buffer offset limit for resuming the acceptance of received packets. This method of configuration enables different peer-provided and administrative priorities to be set up because the intended queue is directly configured instead of determining the priority to queue mapping for local and remote parameters. queue 0 to queue Specify the queue number to which the QoS policy buffer parameters apply 7 pause Pause frames to be sent at the specified buffer limit levels and pause packet settings no-drop The packets for this queue must not be dropped value Enter a number in the range of 0 to 7 to denote the priority to be allocated to the dynamic buffer control mechanism buffer-size Ingress buffer size size Size of the ingress buffer in KB. Enter a number in the range of 0 to 7787. The default is 45 KB. pause-threshold Buffer limit for pause frames to be sent threshold-value Buffer limit at which the port sends the pause to peer in KB. Enter a number in the range of 0 to 7787. The default is 10 KB. resume-offset Buffer offset limit for resuming in KB threshold-value Buffer offset limit at which the port resumes the peer in KB. Enter a number in the range of 1 to 7787. The default is 10 KB. shared-threshold- Buffer shared threshold weight weight size Weightage of the priorities on the shared buffer size in the system. Enter a number in the range of 0 to 9. The default shared threshold weight is 10. Default Command Modes The default size of the ingress buffer is 45 KB. The default buffer limit at which the port sends the pause to peer and recommences the sending of packets to the peer is 10 KB. The default threshold weight of the shared buffer space is 10.
