If you delete the dot1p priority-to-priority group mapping (no priority pgid command) before
you apply the new DCB map, the default PFC and ETS parameters are applied on the interfaces. This
change may create a DCB mismatch with peer DCB devices and interrupt the network operation.
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
1Enter 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
2Apply 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:
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 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.
Step Task Command Command Mode
1Create 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.
