Example configuration provides an easy and flexible technique to accommodate both administratively-configured and peer-configured priorities. Dell(conf-dcb-buffer-thr)#priority 0 buffer-size 52 pausethreshold 16 resume-offset 10 shared-threshold-weight 7 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 pause-threshold threshold-value resume-offset threshold-value shared-threshold-weight size policy-name queue 0 to queue 7 pause no-drop value buffer-size size pause-threshold threshold-value 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. Specify the queue number to which the QoS policy buffer parameters apply Pause frames to be sent at the specified buffer limit levels and pause packet settings The packets for this queue must not be dropped Enter a number in the range of 0 to 7 to denote the priority to be allocated to the dynamic buffer control mechanism Ingress buffer size Size of the ingress buffer in KB. Enter a number in the range of 0 to 7787. The default is 45 KB. Buffer limit for pause frames to be sent 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. Data Center Bridging (DCB) 725
