Creating an FCoE map
An FCoE map consists of:
• An association between the dedicated VLAN used to carry FCoE traffic and SAN fabric where the
storage arrays are installed. Use a separate FCoE VLAN for each fabric to which 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 vice versa.
• 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
1 Create an FCoE map which contains parameters used
in the communication between servers and a SAN
fabric.
fcoe-map map-name
CONFIGURATION
2 Configure the association between the dedicated
VLAN (configured in Creating an FCoE 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
3 Add a text description of the settings in the FCoE map.
Maximum: 32 characters.
description text FCoE MAP
4 Specify 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.
You must enter a unique MAC address prefix as the
FC-MAP value for each fabric.
Range: 0EFC00–0EFCFF.
Default: None.

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

6 Enable the monitoring FIP keep-alive messages (if it is
disabled) to detect if other FCoE devices are
reachable. Default: FIP keep-alive monitoring is
enabled.

7 Configure the time interval (in seconds) used to
transmit FIP keepalive advertisements.
Range: 8-90 seconds. Default: 8 seconds.
