Usage Information The following table describes the output elds displayed for the show running-config dcb-buffer-threshold command:
Field Description
Prole name Name of the DCB buer threshold prole
Priority The priority of the queue for which the buer space settings
apply
buer-size Ingress buer size
pause-threshold-value Buer limit at which the port sends the pause to peer in KB.
resume-threshold-value Buer oset limit at which the port resumes the peer in KB.
Example
