Table 63. S5000 NPIV Proxy Gateway: Terms and Definitions (continued)
Term Description
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. 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 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
To configure DCB functionality, such as PFC and ETS, on Ethernet ports that support CEE traffic, 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, configure
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 traffic 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.
An FCoE map applies the following parameters on server-facing Ethernet and fabric-facing FC ports:
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.
A server uses the priority to select an upstream FCoE forwarder (FCF priority).
FIP keepalive (FKA) advertisement timeout.
NOTE:
In each FCoE map, the fabric ID, FC-MAP value, and FCoE VLAN must be unique. To access one SAN fabric, use
one FCoE map. You cannot use the same FCoE map to access different fabrics.
When you configure an S5000 as an NPG, FCoE transit with FIP snooping is automatically enabled and configured using the
parameters in the FCoE map applied to server-facing Ethernet and fabric-facing FC interfaces (refer to FIP Snooping on an
NPIV Proxy Gateway).
After you apply an FCoE map on an FC port, when you enable the port (using the no shutdown command), the NPG starts
sending FIP multicast advertisements on behalf of the FC port to downstream servers to advertise the availability of a new FCF
