Applying a DCB Map on Server-Facing Ethernet Ports
You can apply a DCB map only on a physical Ethernet interface and can apply only one DCB map per
interface.
Task Command Command Mode
Enter Interface Configuration
mode on a server-facing port to
apply a DCB map.

fortygigabitEthernet
slot/port}
CONFIGURATION
Apply the DCB map on an
Ethernet port. Repeat this step to
apply a DCB map to more than
one port.

Creating an FCoE VLAN
Create a dedicated VLAN to send and receive FC traffic over FCoE links between servers and a fabric over
an NPG. The NPG receives FCoE traffic and forwards de-capsulated FC frames over FC links to SAN
switches in a specified fabric.
When you apply an FCoE map to an Ethernet port, the port is automatically configured as a tagged
member of the FCoE VLAN.
Task
Command Command Mode
Create the dedicated VLAN for
FCoE traffic.
The range is from 2 to 4094.
VLAN 1002 is commonly used to
transmit FCoE traffic.

vlan-id
CONFIGURATION
Creating an FCoE Map
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.
Task
Command Command Mode
Create an FCoE map.
fcoe-map map-name
CONFIGURATION
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.
The range is from 2 to 4094.
