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.
1 Create an FCoE map that contains parameters used in the communication between servers and a SAN
fabric.
CONFIGURATION mode
fcoe-map map-name
2 Configure 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
FCoE MAP mode
fabric-id fabric-num vlan vlan-id
3 Add a text description of the settings in the FCoE map. Maximum: 32 characters.
FCoE MAP mode
description text
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. Enter a unique MAC
address prefix as the FC-MAP value for each fabric. Range: 0EFC00–0EFCFF. Default: None.
FCoE MAP mode
fc-map fc-map-value
5 Configure the priority used by a server CNA to select the FCF for a fabric login (FLOGI). Range: 1–255.
Default: 128.
FCoE MAP mode
