C9000 Series Syntax Parameters dcb pfc-queues value value Enter the number of PFC queues in the range of 0 through 4. The number of ports supported based on lossless queues configured will depend on the buffer. Default The default number of PFC queues in the system is 2 for S4810 and 1 for S6000 platforms. Command Modes CONFIGURATION Command History Version 9.9(0.0) Description Introduced on the C9010. 9.7(0.1) Introduced on the S3048-ON and S4048-ON. 9.7(0.0) Introduced on the S6000-ON. 9.3(0.0) Introduced on the S4810 and S6000 platforms. Usage Information Example 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. Dell(conf)#dcb pfc-queues 4 Data Center Bridging (DCB) 573
