Term Description
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 the
Aggregator with the Ethernet ports that support CEE traffic 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 configure 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 traffic 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.
An FCoE map applies the following parameters on server-facing Ethernet and fabric-facing FC ports on
the Aggregator:
• The dedicated FCoE VLAN used to transport FCoE storage traffic.
• The FC-MAP value used to generate a fabric-provided MAC address.
• The association between the FCoE VLAN ID and FC fabric ID where the desired storage arrays are
installed. Each Fibre Channel fabric serves as an isolated SAN topology within the same physical
network.
• The priority used by a server to select an upstream FCoE forwarder (FCF priority).
• FIP keepalive (FKA) advertisement timeout.
