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
802.1Qbb
