Field Description
resume-
threshold-value
Buffer offset limit at which the port resumes the peer in KB.
Example
DellEMC# show running—config dcb-buffer-threshold
!
dcb-buffer-threshold test1
pfc priority 0 buffer-size 40
pfc priority 3 buffer-size 50
!
dcb-buffer-threshold test2
pfc priority 0 buffer-size 80 pause-threshold 50
!
dcb-buffer-threshold test3
pfc priority 0 buffer-size 80 pause-threshold 60 resume-threshold 30

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.
service-class buffer shared-threshold-weight
Create a service class and associate the threshold weight of the shared buffer with each of the queues per port in the egress
direction.
Syntax
[No] Service-class buffer shared-threshold-weight {[queue0 number] ||
[queue1 number] || [queue2 number] || [queue3 number] || [queue4 number] ||
[queue5 number] || [queue6 number] || [queue7 number]}
Parameters
buffer Define the shared buffer settings
