Version Description

9.3(0.0) Introduced on the S4810 and S4820T platforms.
Usage Information You can congure up to a maximum of four lossless (PFC) queues. By conguring four lossless queues, you can
congure four dierent 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 le transfers. You can congure the amount of buer space for each priority and the pause or
resume thresholds for the buer. This method of conguration enables you to manage and administer the behavior
of lossless queues.
