Thisfunctionality is supported on the S4810 platform.DCB Map: Configuration ProcedureA DCB map consists of PFC and ETS parameters. By default, PFC is not enabled on any 802.1p priorityand ETS allocates equal bandwidth to each priority. To configure user-defined PFC and ETS settings, youmust create a DCB map.Step Task Command Command Mode1 Enter global configuration mode to create aDCB map or edit PFC and ETS settings.dcb-map name CONFIGURATION2 Configure the PFC setting (on or off) and theETS bandwidth percentage allocated to trafficin each priority group, or whether the prioritygroup traffic should be handled with strictpriority scheduling. You can enable PFC on amaximum of two priority queues on aninterface. Enabling PFC for dot1p prioritiesmakes the corresponding port queue lossless.The sum of all allocated bandwidthpercentages in all groups in the DCB mapmust be 100%. Strict-priority traffic is servicedfirst. Afterwards, bandwidth allocated to otherpriority groups is made available and allocatedaccording to the specified percentages. If apriority group does not use its allocatedpriority-groupgroup_num {bandwidthpercentage | strict-priority} pfc {on | off}DCB MAPData Center Bridging (DCB) 563
