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 to be
allocated for each priority and the pause or resume thresholds for the buer. This method of conguration
enables you to eectively manage and administer the behavior of lossless queues.
