Description
9.3(0.0)
Introduced on the S4810 and S4820T 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.
