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.
