Assign the dcb buffer threshold policy on the stack ports. To apply the dcb buffer threshold policy on the stack-units, use the
configuration mode. To apply on front-end ports, use the interface mode.

Parameters

Usage
Information
You can configure up to a maximum of four lossless (PFC) queues. By configuring four lossless queues,
you can configure four different 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 file transfers. You can configure the amount of buffer
space for each priority and the pause or resume thresholds for the buffer. This method of configuration
enables you to manage and administer the behavior of lossless queues.
