threshold-value peak-headroom headroom-value resume-offset threshold-value
shared-threshold-weight size
priority
Configure the priority for the PFC threshold to be allocated to the buffer space parameters.
Syntax
priority value buffer-size size pause-threshold threshold-value resume-offset
threshold-value shared-threshold-weight size
Parameters
priority Specify the priority of the queue for which the buffer space settings apply.
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.
NOTE: In addition to the specified pause-threshold value, pause frames are
sent only when the buffer usage exceeds some percentage of the shared
buffer.
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 stopping the transmission of pause frames.
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.

Usage Information
For each priority, 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. When
