Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Supported on the FN I/O Aggregator.

Usage Information DCB is not supported if you enable link-level flow control on one or more interfaces.
dcb-policy buer-threshold (Global Conguration)
Assign the dcb buer threshold policy on the stack ports. To apply the dcb buer threshold policy on the stack-units, use the conguration
mode. To apply on front-end ports, use the interface mode.
Syntax
dcb-policy buffer-threshold stack-unit all stack-ports all profile-name
Parameters
dcb-buer-
threshold
Congure the prole name for the DCB buer threshold.
prole-name Enter the name of the prole, which can be a string of up to 32 characters in length.
stack-unit all Enter the stack unit identication. Indicates the specic the stack unit or units. Entering

Version Description
9.9(0.0) Introduced on the FN IOM.
9.3(0.0) Introduced on the MXL platform.
Usage Information You can congure up to a maximum of four lossless (PFC) queues. By conguring four lossless queues, you can
congure four dierent priorities and assign a particular priority to each application that your network is used to
process. For example, you can assign a higher priority for time-sensitive applications and a lower priority for other
services, such as le transfers. You can congure the amount of buer space for each priority and the pause or
resume thresholds for the buer. This method of conguration enables you to manage and administer the behavior
of lossless queues.
