Creating an FCoE Map An FCoE map consists of:
• An association between the dedicated VLAN, used to carry FCoE traffic, and the SAN fabric where the
storage arrays are installed. Use a separate FCoE VLAN for each fabric to which the FCoE traffic is
forwarded. Any non-FCoE traffic sent on a dedicated FCoE VLAN is dropped.
• The FC-MAP value, used to generate the fabric-provided MAC address (FPMA). The FPMA is used by
servers to transmit FCoE traffic to the fabric. You can associate an FC-MAP with only one FCoE VLAN
and conversely, associate an FCoE VLAN with only one FC-MAP.
• FCF priority, the priority used by a server CNA to select an upstream FCoE forwarder (FCF)
• FIP keepalive (FKA) advertisement timeout
The values for the FCoE VLAN, fabric ID and FC-MAP must be unique. Apply an FCoE map on
downstream server-facing Ethernet ports and upstream fabric-facing Fibre Channel ports.
Step Task Command Command Mode
1Create an FCoE map that contains parameters
used in the communication between servers
and a SAN fabric.
fcoe-map map-name CONFIGURATION
2Configure the association between the
dedicated VLAN and the fabric where the
desired storage arrays are installed. The fabric
and VLAN ID numbers must be the same.
Fabric and VLAN ID range: 2-4094.
For example: fabric id 10 vlan 10
fabric-id fabric-num
vlan vlan-id
FCoE MAP
3Add a text description of the settings in the
FCoE map.
Maximum: 32 characters.
description text FCoE MAP
4Specify the FC-MAP value used to generate a
fabric-provided MAC address, which is
required to send FCoE traffic from a server on
the FCoE VLAN to the FC fabric specified in
Step 2. Enter a unique MAC address prefix as
the FC-MAP value for each fabric.
Range: 0EFC00–0EFCFF.
Default: None.

5Configure the priority used by a server CNA to
select the FCF for a fabric login (FLOGI).
Range: 1-255. Default: 128.
