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.
shared-threshold-
weight
Buffer shared threshold 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 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.

Usage Information
You must apply this buffer policy at the interface level for the attributes to be
applicable in conjunction with the DCB input policy.
For each QoS policy buffer, you can specify the shared buffer threshold limit, the
ingress buffer size, buffer limit for pausing the acceptance of packets, and the
Data Center Bridging (DCB)
