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. Data center bridging (DCB) features are auto-configured in standalone mode and
supported in stacking mode.
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:
