Term Description
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. Server CNAs use FIP 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
To congure DCB functionality, such as PFC and ETS, on Ethernet ports that support CEE trac, use a data center bridging (DCB) map.
DCB maps are DCBx-enabled by default. For more about PFC and ETS, refer to Data Center Bridging (DCB).
By default, no PFC and ETS settings in a DCB map are applied to Ethernet ports when you enable them. On an NPG, congure PFC and
ETS parameters in a DCB map and then apply the map to server-facing Ethernet ports (for more information, refer to Creating a DCB
Map).
FCoE Maps
To identify the SAN fabric to which FCoE storage trac is sent, use an FCoE map.
Using an FCoE map, an 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.
