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 for each priority and the pause or resume thresholds for the buffer. This method of configuration enables you to manage and administer the behavior of lossless queues.
Example for Configuration Mode
Dell(conf)# dcb-policy buffer-threshold stack-unit all stack-ports all test
Example for Interface Mode
Dell(conf-if-te-1/1)# dcb-policy buffer-threshold test
