Data Center Bridging (DCB)

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 Networking operating software (FTOS) commands for data center bridging features include
