priority
Congure the priority for the PFC threshold to be allocated to the buer space parameters. This utility is supported on the S4810
platforms.
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
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 resuming in KB
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.
Default The default size of the ingress buer is 45 KB. The default buer 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 buer space is 10.
