settings, and apply the new map to the interfaces to override the previous DCB map settings. Then,
delete the original dot1p priority-to-priority group mapping.
• 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.
1 Enter 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.
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.

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 , the port is automatically configured as a tagged member
of the FCoE VLAN.
