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 to be allocated for each priority and the pause or resume thresholds for the buffer. This method of
configuration enables you to effectively manage and administer the behavior of lossless queues.
