the system. This utility is supported on the S4810, S4820T, and MXL platforms. This command is not
supported on the S6000 platform because it does not contain stack ports.

Usage
Information
You can configure up to a maximum of 4 lossless (PFC) queues. By configuring 4
lossless queues, you can configure 4 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 configuraiton enables you to effectively manage and administer the
behavior of lossless queues.
