Converged Enhanced Ethernet on the HP ProCurve 6120XG Switch Terminology Terminology CEE Converged Enhanced Ethernet-a set of four new IEEE draft standards that enhance Ethernet and data link layer protocols in support of lossless Ethernet for storage protocols. CNA Converged Network Adapter-a server NIC with features to support a combination of FCoE and traditional Ethernet traffic. CNA Enode/Enode Converged Network Adapter End Node COS Class of Service-traffic categories grouped with a specific type of service. DCBX Data Center Bridging Exchange-The protocol over Link Layer Discovery Protocol (LLDP) in which CEE devices exchange information about their configured capabilities. ETS Enhanced Transmission Scheduling-Provides improved transmit performance and metering based on traffic types or priorities and a common management framework for assignment of bandwidth to traffic classes. FCoE Fibre Channel over Ethernet-draft standard defines the frame formats and encoding used in the encapsulation of Fibre Channel frames into Ethernet frames (FCoE) and the FCoE Initialization Protocol (FIP). FCF Fibre Channel Forwarder-The bridge point between Ethernet and Fibre Channel fabrics. It bridges FCoE to FC. FC-MAP MAC prefix (first 3 bytes) used by the FCF to generate locally unique fabric MAC addresses. These addresses are known as FPMA (Fabric Provided MAC Address). LLDP Link Layer Discovery Protocol-An LLDP packet contains data about the transmitting switch and port. The switch advertises itself to adjacent (neighbor) devices by transmitting LLDP data packets out all ports on which outbound LLDP is enabled, and reading LLDP advertisements from neighbor devices on ports that are inbound LLDP-enabled. (LLDP is a one-way protocol and does not include any acknowledgement mechanism.) PFC Priority-based Flow Control-Provides a link level flow control mechanism that can be controlled independently for each 802.1p priority. The goal is to enable lossless semantics for a subset of the Layer 2 flows on an Ethernet link. Requires 802.1Q tagged links. 6-4

for storage protocols.
CNA
Converged Network Adapter—a server NIC with features to support a
combination of FCoE and traditional Ethernet traffic.
CNA Enode/Enode
Converged Network Adapter End Node
COS
Class of Service—traffic categories grouped with a specific type of service.
DCBX
Data Center Bridging Exchange—The protocol over Link Layer Discovery
Protocol (LLDP) in which CEE devices exchange information about their
configured capabilities.
ETS
Enhanced Transmission Scheduling—Provides improved transmit perfor-
mance and metering based on traffic types or priorities and a common
management framework for assignment of bandwidth to traffic classes.
FCoE
Fibre Channel over Ethernet—draft standard defines the frame formats and
encoding used in the encapsulation of Fibre Channel frames into Ethernet
frames (FCoE) and the FCoE Initialization Protocol (FIP).
FCF
Fibre Channel Forwarder—The bridge point between Ethernet and Fibre
Channel fabrics. It bridges FCoE to FC.
FC-MAP
MAC prefix (first 3 bytes) used by the FCF to generate locally unique fabric
MAC addresses. These addresses are known as FPMA (Fabric Provided MAC
Address).
LLDP
Link Layer Discovery Protocol—An LLDP packet contains data about the
transmitting switch and port. The switch advertises itself to adjacent (neigh-
bor) devices by transmitting LLDP data packets out all ports on which out-
bound LLDP is enabled, and reading LLDP advertisements from neighbor
devices on ports that are inbound LLDP-enabled. (LLDP is a one-way protocol
and does not include any acknowledgement mechanism.)
PFC
Priority-based Flow Control—Provides a link level flow control mechanism
that can be controlled independently for each 802.1p priority. The goal is to
enable lossless semantics for a subset of the Layer 2 flows on an Ethernet link.
