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 {ets | pfc} enable
Enable priority flow control or enhanced transmission selection on interface.
Syntax
dcb {ets | pfc} enable
● To disable ETS on interface, use “no dcb ets enable” command.
