Table 89. FN IOM with the FC Flex IO module NPIV Proxy Gateway: Terms and Definitions
Term Description
FC port Fibre Channel port on the FN IOM 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 the FN IOM
with the FC Flex IO module NPIV proxy gateway.
N port Port mode of the FN IOM with the FC Flex IO module FC port that connects
to an F port on an FC switch in a SAN fabric. On the FN IOM 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 FN IOM 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 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 interoperate 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 an
upstream FCoE switch operating as an FCF. FIP keepalive messages
maintain the connection between an FCoE initiator and an FCF.
NPIV N-port identifier virtualization: The capability to map multiple FCoE links
from downstream ports to a single upstream FC link.
