Data Center Bridging (DCB)
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 local area network (LAN), server, and storage traffic.
The Dell Networking Operating System (OS) 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.
