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.
Step Task Command Command Mode
1
Enter interface configuration mode on a
server-facing port or port channel to apply a
DCB map.
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.
interface
{tengigabitEthernet slot/
port | fortygigabitEthernet
slot/port}
CONFIGURATION
2
Apply the DCB map on an Ethernet port or
port channel. The port is configured with the
PFC and ETS settings in the DCB map; for
example:
FTOS# interface tengigabitEthernet 0/0
FTOS(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 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.
Step Task Command Command Mode
1
Create the dedicated VLAN for FCoE traffic.
Range: 2-4094.
VLAN 1002 is commonly used to transmit
FCoE traffic.
interface vlan vlan-id CONFIGURATION
When you apply an FCoE map to an Ethernet port (Applying an FCoE map on server-facing Ethernet
ports), the port is automatically configured 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 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
