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. DCB
features are auto-configured in standalone mode.
The Dell Networking OS commands for DCB 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 auto-detect on-next-reload
● show qos dcb-map
PFC Commands
● clear pfc counters
● show interface pfc
● show interface pfc statistics
ETS Commands
● clear ets counters
● show interface ets
DCBX Commands
● dcbx version
● clear dcbx counters
● show dcb
● show interface dcbx detail
