Field Description
Field Description
Profile name Name of the DCB buffer threshold profile
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.
Example
DellEMC# show running—config dcb-buffer-threshold
!
dcb-buffer-threshold test1
pfc priority 0 buffer-size 40
pfc priority 3 buffer-size 50

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
