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.

The Dell Force10 operating software (FTOS) commands for data center bridging features include

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:
