dcb-policy dcb-buffer-threshold (Global Configuration)Assign the DCB policy to the DCB buffer threshold profile on stack ports that applies globally throughoutthe system. This utility is supported on the S4810 and platforms. This command is not supported on theS6000 platform because it does not contain stack ports.Syntax dcb-policy buffer-threshold stack-unit all stack-ports allprofile-nameParameters dcb-buffer-thresholdConfigure the profile name for the DCB buffer thresholdprofile-name Enter the name of the profile, which can be a string of up to32 characters in length.stack-unit all Enter the stack unit identification. Indicates the specific thestack unit or units. Entering all shows the status for all stacks.stack-port all Enter the port number of a port in a switch stack.Default NoneCommandModesCONFIGURATION modeCommandHistory Version 9.3(0.0) Introduced on the S4810 and S4820T platforms.UsageInformationYou can configure up to a maximum of four lossless (PFC) queues. By configuringfour lossless queues, you can configure four different priorities and assign aparticular priority to each application that your network is used to process. Forexample, you can assign a higher priority for time-sensitive applications and alower priority for other services, such as file transfers. You can configure theamount of buffer space to be allocated for each priority and the pause or resumethresholds for the buffer. This method of configuration enables you to effectivelymanage and administer the behavior of lossless queues.Example Dell(conf)# dcb-policy buffer-threshold stack-unit all stack-ports all testshow qos dcb-buffer-thresholdDisplays the DCB buffer threshold assigned to a QoS policy.
