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 68. 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.
