Field Description
Priority The priority of the queue for which the buffer space settings apply
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.
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.
Example
Dell#show run buffer-threshold
