priority
Congure the priority for the PFC threshold to be allocated to the buer 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 buer space settings apply.
value Enter a number in the range of 0 to 7 to denote the priority to be allocated to the dynamic
buer control mechanism.
buer-size Ingress buer size.
size Size of the ingress buer in KB. Enter a number in the range of 0 to 7787. The default is
45 KB.
pause-threshold Buer limit for pause frames to be sent.
NOTE: In addition to the specied pause-threshold value, pause frames are sent
only when the buer usage exceeds some percentage of the shared buer.
threshold-value Buer 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-oset Buer oset limit for stopping the transmission of pause frames.
threshold-value Buer oset 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
Buer shared threshold weight
size Weightage of the priorities on the shared buer size in the system. Enter a number in the
range of 0 to 9. The default shared threshold weight is 10.
