51031-00 A viiPrefaceThis document describes how to install and certify a pilot unified fabricconfiguration. This configuration demonstrates lossless Ethernet and data centerbridging (DCB), which includes priority flow control (PFC), enhanced transmissionselection (ETS), and data center bridging exchange protocol (DCBX) for a FibreChannel and 10Gb Ethernet unified fabric.Intended AudienceThis guide is for system engineers and planners who want to provide convergednetworking products, solutions, and services to their customers. It is also intendedfor network planners and administrators who are implementing a convergednetwork for their company. This guide describes how to install and validate a pilotconverged network in preparation for production deployment.This guide assumes basic knowledge of Enhanced Ethernet and the associatedstandards. If the you are not familiar with Fibre Channel over Ethernet (FCoE) andEnhanced Ethernet, review the documents listed in “Related Materials” onpage vii.Related MaterialsIn addition to this guide, the FCoE Design Guide, developed jointly by Cisco andQLogic (Cisco document number C11-569320-01), is a valuable resource and isreferenced throughout this guide.The following links provide more detailed information, and connect to the IEEEdocuments that define the Enhanced Ethernet functions: P802.1Qbb: Priority-based Flow Controlhttp://www.ieee802.org/1/files/public/docs2008/bb-pelissier-pfc-proposal-0508.pdf P802.1Qaz: Enhanced Transmission Selection (Priority Groups):http://www.ieee802.org/1/files/public/docs2008/az-wadekar-ets-proposal-0608-v1.01.pdf P802.1Qaz: DCB Capability Exchange Protocol (DCBX):http://www.ieee802.org/1/files/public/docs2008/az-wadekar-dcbx-capability-exchange-discoveryprotocol-1108-v1.01.pdf
