Data Center Technology Commands 1139Syntaxdatacenter-bridgingDefault ConfigurationThis command has no default configuration.Command ModeInterface Configuration (Ethernet) modeUser GuidelinesNOTE: This command is only available on N40xx series switches.Datacenter bridging mode is only available on physical interfaces, not onport-channel interfaces. To ensure proper operation, users must configure allphysical interfaces in a port channel to have the same data-center bridgingconfiguration.Exampleconsole#configconsole(config)#interface range ethernet allconsole(config-if)#datacenter-bridgingconsole(config-if-dcb)#priority-flow-control mode onconsole(config-if-dcb)#priority-flow-control priority 1 no-droplldp dcbx versionUse the lldp dcbx version command in Global Configuration mode toconfigure the administrative version for the Data Center Bridging CapabilityExchange (DCBX) protocol. This command enables the switch to support aspecific version of the DCBX protocol or to detect the peer version and matchit. DCBX can be configured to operate in IEEE mode or CEE mode or CINmode. In auto mode, version detection is based on the peer device DCBXversion. The switch operates in either IEEE or one of the legacy modes oneach interface.NOTE: CIN is Cisco Intel Nuova DCBX (version 1.0). CEE is converged enhancedethernet DCBX (version 1.06).Use the no form of the command to reset the dcbx version to the defaultvalue of auto.
