Configuration manual

Term Description
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.
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 configure DCB functionality, such as PFC and ETS, on MXL
10/40GbE Switch and M I/O Aggregator with the FC Flex IO module Ethernet ports that support CEE
traffic and are DCBx-enabled, by default. For more information, on PFC and ETS, see Data Center
Bridging (DCB).
By default, no PFC and ETS settings in a DCB map are applied to MXL 10/40GbE Switch and M I/O
Aggregator with the FC Flex IO module Ethernet ports when they are enabled. On an MXL 10/40GbE
Switch and M I/O Aggregator with the FC Flex IO module NPG, you must configure PFC and ETS
parameters in a DCB map and then apply the map to server-facing Ethernet ports (see the “Creating a
DCB map" section).
