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.
