Version Description
9.3(0.0) Introduced on the S4810, S4820T, and S6000 platforms.
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.
