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 software 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.
