Step Task Command Command Mode
You cannot apply a DCB map on a port channel. However,
you can apply a DCB map on the ports that are members
of the port channel.
2
Apply the DCB map on an Ethernet port or port channel.
The port is congured with the PFC and ETS settings in
the DCB map, for example:
Dell# interface tengigabitEthernet 0/0
Dell(config-if-te-0/0)# dcb-map SAN_DCB1
Repeat this step to apply a DCB map to more than one
port or port channel.

Creating an FCoE VLAN
Create a dedicated VLAN to send and receive Fibre Channel trac over FCoE links between servers and a fabric over an NPG. The
NPG receives FCoE trac and forwards decapsulated FC frames over FC links to SAN switches in a specied fabric.

1
Create the dedicated VLAN for FCoE trac.
Range: 2–4094.
VLAN 1002 is commonly used to transmit FCoE trac.
interface vlan vlan-id
CONFIGURATION
When you apply an FCoE map to an Ethernet port , the port is automatically congured as a tagged member of the FCoE VLAN.
Creating an FCoE Map
An FCoE map consists of:
• An association between the dedicated VLAN, used to carry FCoE trac, and the SAN fabric where the storage arrays are
installed. Use a separate FCoE VLAN for each fabric to which the FCoE trac is forwarded. Any non-FCoE trac 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
trac 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.

Create an FCoE map that contains parameters used in the
communication between servers and a SAN fabric.

Congure 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
