NPIV Proxy Gateway: Protocol Services
An MXL 10/40GbE Switch and M I/O Aggregator with the FC Flex IO module NPG provides the following
protocol services:
• Fibre Channel service to create N ports and log in to an upstream FC switch.
• FCoE service to perform:
• Virtualization of FC N ports on an NPG so that they appear as FCoE FCFs to downstream servers.
• NPIV service to perform the association and aggregation of FCoE servers to upstream F ports on core
switches (through N ports on the NPG). Conversion of server FLOGIs and FDISCs, which are received
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.
