Term Description
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 congure DCB parameters, including priority-based ow 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 trac to both
downstream FCoE and upstream FC devices. An NPIV proxy gateway functions as an FCF
to export upstream F port congurations to downstream server CNA ports.
FC-MAP FCoE MAC-address prex — The unique 24-bit MAC address prex 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 congure FCoE and FC parameters on Ethernet and FC ports in a
converged fabric.
FCoE VLAN VLAN dedicated to carrying only FCoE trac between server CNA ports and a SAN fabric.
(FCoE trac must travel in a VLAN.) When you apply an FCoE map on a port, FCoE is
enabled on the port. All non-FCoE trac 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 identier virtualization: The capability to map multiple FCoE links from downstream
ports to a single upstream FC link.
principal switch The switch in a fabric with the lowest domain number. The principal switch accesses the
master name database and the zone/zone set database.
DCB Maps
A Data Center Bridging (DCB) map is used to congure DCB functionality, such as PFC and ETS, on the Aggregator with the
Ethernet ports that support CEE trac and are DCBx-enabled, by default.
By default, no PFC and ETS settings in a DCB map are applied to the Aggregator with the Ethernet ports when they are enabled. On
an Aggregator with the NPG, you must congure PFC and ETS parameters in a DCB map and then apply the map to server-facing
Ethernet ports.
FCoE Maps
An FCoE map is used to identify the SAN fabric to which FCoE storage trac is sent. Using an FCoE map, an Aggregator with the
NPG operates as an FCoE-FC bridge between an FC SAN and FCoE network by providing FCoE-enabled servers and switches with
the necessary parameters to log in to a SAN fabric.
