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.

Dell Networking 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.
