Usage
Information
When you enter the profile name, you enter the DCB buffer threshold configuration mode. 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.
priority
Configure the priority for the PFC threshold to be allocated to the buffer space parameters.
C9000 Series
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
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.
