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.
CONFIGURATION mode
interface tengigabitEthernet slot/port
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.
Repeat this step to apply a DCB map to more than one port or port channel.
INTERFACE mode
dcb-map name
Dell# interface tengigabitEthernet 0/0
Dell(config-if-te-0/0)# dcb-map SAN_DCB1
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 decapsulated FC frames over FC links to SAN
switches in a specified fabric.
1 Create the dedicated VLAN for FCoE traffic. Range: 2–4094.
VLAN 1002 is commonly used to transmit FCoE traffic.
CONFIGURATION mode
interface vlan vlan-id
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 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.
