priority-group bandwidth pfc
— configures the ETS bandwidth allocation and the
PFC setting used to manage the port traffic in an 802.1p priority group.
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
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 7
Specify the queue number to which the QoS policy buffer
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
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.
