9 Data Center Bridging Overview Data center bridging (DCB) refers to a set of IEEE Ethernet enhancements that provide data centers with a single, robust, converged network to support multiple traffic types, including LAN, server, and storage traffic. The Dell Force10 operating software (FTOS) commands for data center bridging features include 802.1Qbb priority-based flow control (PFC), 802.1Qaz enhanced transmission selection (ETS), and the Data Center Bridging Exchange (DCBX) protocol. CLI commands for individual DCB features are as follows: DCB Command • dcb-enable PFC Commands • dcb-input • dcb-policy input • dcb-policy input stack-unit stack-ports all • dcb stack-unit all pfc-buffering pfc-port-count pfc-queues • dcb stack-unit pfc-buffering pfc-port pfc-queues • description • pfc link-delay • pfc mode on • pfc priority • pfc no-drop queues • show dcb • show interface pfc • show interface pfc statistics • show qos priority-groups • show stack-unit stack-ports pfc detail Data Center Bridging | 153
