NPIV Proxy Gateway: Terms and Definitions
The following table describes the terms used in an NPG configuration on the Aggregator.
Table 20. 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.
FC-MAP FCoE MAC-address prefix — The unique 24-bit MAC address prefix in
FCoE packets used to generate a fabric-provided MAC address (FPMA).
The FPMA is required to send FCoE packets from a server to a SAN fabric.
FCoE map Template used to configure FCoE and FC parameters on Ethernet and
FC ports in a converged fabric.
FCoE VLAN VLAN dedicated to carrying only FCoE traffic between server CNA ports
and a SAN fabric. (FCoE traffic must travel in a VLAN.) When you apply an
FCoE map on a port, FCoE is enabled on the port. All non-FCoE traffic is
dropped on an FCoE VLAN.
FIP FCoE Initialization Protocol: Layer 2 protocol for endpoint discovery,
fabric login, and fabric association. FIP is used by server CNAs to discover
