If you delete the dot1p priority-priority group mapping (the 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 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 the interface Conguration mode on a server-facing port or port channel to apply a DCB map.
CONFIGURATION mode
interface {tengigabitEthernet slot/port | fortygigabitEthernet slot/port}
NOTE: 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.
2 Apply the DCB map on an Ethernet port or port channel.
INTERFACE mode
dcb-map name
The port is congured 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
To apply a DCB map to more than one port or port channel, repeat this step.
Creating an FCoE VLAN
Create a dedicated VLAN to send and receive Fibre Channel trac over FCoE links between servers and a fabric over an NPG.
The NPG receives FCoE trac and forwards de-capsulated FC frames over FC links to SAN switches in a specied fabric.
Create the dedicated VLAN for FCoE trac.
CONFIGURATION mode
interface vlan vlan-id
NOTE
: VLAN 1002 is commonly used to transmit FCoE
trac.
When you apply an FCoE map to an Ethernet port, the port automatically congures as a tagged member of the FCoE VLAN. For more
information, refer to Applying a DCB Map on Server-Facing Ethernet Ports.
FCoE Maps
To identify the SAN fabric to which FCoE storage trac is sent, use an FCoE map.
Using an FCoE map, an NPG operates as an FCoE-FC bridge between an FC SAN and FCoE network by providing FCoE-enabled servers
and switches with the necessary parameters to log in to a SAN fabric.
