Dell 9.7(0.0) manual Qos-policy-buffer, Policy-name, Queue 0 to, No-drop

congestion on a queue for a specified priority, it sends a pause frame for the 802.1p priority traffic to the transmitting device.

You can use the priority command to set up both the administrative and peer- related PFC priorities. For example, you can configure the intended buffer configuration for all eight priorities. If you configure the number of lossless queues as 4 and if the administrator-configured priorities configured within the DCB input policy is applied, then the configuration for those priorities are pre-designed. However, if the peer-provided priorities are applied, although a DCB input policy is present, the peer-provided priorities become effective for buffer configuration. This method of configuration provides an easy and flexible technique to accommodate both administratively-configured and peer-configured priorities.

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. This utility is supported on the S6000.

Parameters	Name of the QoS policy buffer that is applied to an interface
policy-name
	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	Specify the queue number to which the QoS policy buffer
queue 7	parameters apply
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
