The following table describes the output fields displayed for the show interface pfc buffer-
threshold command:
Field
Description
queue Number of the queue
lossless Whether the queue is a lossy or lossless queue for which buffer threshold is
configured
buffer-size Ingress buffer size
pause-threshold-
value
Buffer limit at which the port sends the pause to peer in KB.
resume-
threshold-value
Buffer offset limit at which the port resumes the peer in KB.
shared threshold
weight
Weightage of the priorities on the shared buffer size in the system.
dcb pfc-queues
Configure the number of PFC queues.
Syntax
dcb pfc-queues value
Parameters
value Enter the number of PFC queues in the range of 0 through 4. The number of ports
supported based on lossless queues configured will depend on the buffer.
Default The default number of PFC queues in the system is 2 for S4810 and 1 for S6000 platforms.
