received over the Aggregator with the ENode ports, are converted into FDISCs addressed to the
upstream F ports on core switches.
NPIV Proxy Gateway Functionality
The Aggregator with the NPG provides the following functionality in a storage area network:
• FIP Snooping bridge that provides security for FCoE traffic using ACLs.
• 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.
NPIV Proxy Gateway: Terms and Definitions
The following table describes the terms used in an NPG configuration on the Aggregator.
Table 23. Aggregator with the NPIV Proxy Gateway: Terms and Definitions
Term Description
FC port Fibre Channel port on the Aggregator 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
Aggregator with the NPIV proxy gateway.
N port Port mode of an Aggregator with the FC port that connects to an F port
on an FC switch in a SAN fabric. On an Aggregator with the 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 Aggregator with the 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 can
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.
