Data Center Bridging (DCB) for Intel® Network Connections:
Intel® FCoE/DCB User Guide
Overview
Data Center Bridging is a collection of standards-based extensions to classical Ethernet. It provides a lossless data center
transport layer that enables the convergence of LANs and SANs onto a single Unified Fabric. In addition to supporting Fibre
Channel Over Ethernet (FCoE), it enhances the operation of other business-critical traffic.
Data Center Bridging is a flexible framework that defines the capabilities required for switches and end points to be part of a
data center fabric. It includes the following capabilities:
Priority-based flow control (PFC; IEEE 802.1Qbb)
Enhanced transmission selection (ETS; IEEE 802.1Qaz)
Congestion notification (CN)
Extensions to the Link Layer Discovery Protocol standard (IEEE 802.1AB) that enable Data Center Bridging Capability
Exchange Protocol (DCBX)
There are two supported versions of DCBX:
Version 1: This version of DCBX is referenced in Annex F of the FC-BB-5 standard (FCoE) as the version of DCBX used
with pre-FIP FCoE implementations.
Version 2: The specification can be found as a link within the following document:

DCB for Windows
Configuration
Many DCB functions can be configured or revised using Intel® PROSet for Windows Device Manager, from the Data Center tab.
You can use the Intel® PROSet for Windows Device Manager to perform the following tasks:
Display status
Priority Group
Priority Flow Control
FCoE Priority
iSCSI Priority
Non-operational status: If the Status indicator shows that DCB is non-operational, there may be a
number of possible reasons.
1. DCB is not enabled. Select the checkbox to enable DCB.
2. At least one of the DCB features is in a non-operational state. The features that contribute to the
non-operational status are PFC and APP:FCoE.
