Addendum

over MXL 10/40GbE Switch and M I/O Aggregator with the FC Flex IO module ENode ports, are
converted into FDISCs addressed to the upstream F ports on core switches.
NPIV Proxy Gateway Functionality
An MXL 10/40GbE Switch and M I/O Aggregator with the FC Flex IO module NPG provides the following
functionality in a storage area network:
• FIP Snooping bridge that provides security for FCoE traffic using ACLs (see FCoE Transit chapter).
• FCoE gateway that provides FCoE-to-FC bridging. N-port virtualization using FCoE maps exposes
upstream F ports as FCF ports to downstream server-facing ENode ports on the NPG (see FCoE
Maps).
NPIV Proxy Gateway: Terms and Definitions
The following table describes the terms used in an NPG configuration on the MXL 10/40GbE Switch and
M I/O Aggregator with the FC Flex IO module.

Terms and Definitions
Term Description
FC port Fibre Channel port on an MXL 10/40GbE Switch and M I/O Aggregator
with the FC Flex IO module FC module that operates in autosensing, 2, 4,
or 8 Gigabit mode. On an NPIV proxy gateway, an FC port can be used
as a downlink for a server connection and an uplink for a fabric
connection.
F port Port mode of an FC port connected to an end node (N) port on an MXL
10/40GbE Switch and M I/O Aggregator with the FC Flex IO module
NPIV proxy gateway.
N port Port mode of an MXL 10/40GbE Switch and M I/O Aggregator with the
FC Flex IO module FC port that connects to an F port on an FC switch in
a SAN fabric. On an MXL 10/40GbE Switch and M I/O Aggregator with
the FC Flex IO module NPIV proxy gateway, an N port also functions as a
proxy for multiple server CNA-port connections
ENode port Port mode of a server-facing MXL 10/40GbE Switch and M I/O
Aggregator with the FC Flex IO module Ethernet port that provides
access to FCF functionality on a fabric.
CNA port N-port functionality on an FCoE-enabled server port. A converged
network adapter (CNA) can use one or more Ethernet ports. CNAs have
the capability to encapsulate Fibre Channel frames in Ethernet for FCoE
transport and de-encapsulate Fibre Channel frames from FCoE to native
Fibre Channel.
DCB map Template used to configure DCB parameters, including priority-based
flow control (PFC) and enhanced transmission selection (ETS), on CEE
ports.
Fibre Channel fabric Network of Fibre Channel devices and storage arrays that inter-operate
and communicate.
FCF Fibre Channel forwarder: FCoE-enabled switch that can forward FC
traffic to both downstream FCoE and upstream FC devices. An NPIV
proxy gateway functions as an FCF to export upstream F port
configurations to downstream server CNA ports.
