Qos-Policy-Buffer - Dell C9000 Series Reference Manual

configuration provides an easy and flexible technique to accommodate both
administratively-configured and peer-configured priorities.
Example
Dell(conf-dcb-buffer-thr)#priority 0 buffer-size 52 pause-
threshold 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. .

Parameters

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.
