Applying an FCoE Map on Fabric-Facing FC Ports
By default, FC ports are congured to operate in N Port mode to connect to an F port on an FC switch in a fabric.
You can apply only one FCoE map on an FC port.
When you apply an FCoE map on a fabric-facing FC port, the FC port becomes part of the FCoE fabric, whose settings in the FCoE map
are congured on the port and exported to downstream server CNA ports.
Each FC port is associated with an Ethernet MAC address (FCF MAC address). When you enable a fabric-facing FC port, the FCoE map
applied to the port starts sending FIP multicast advertisements using the parameters in the FCoE map over server-facing Ethernet ports. A
server sees the FC port with its applied FCoE map as an FCF port.
1 Congure a fabric-facing FC port.
CONFIGURATION mode
interface fibrechannel slot/ port
For information about how to congure FC port settings, refer to Fibre Channel Interface.
2 Apply the FCoE and FC fabric congurations in an FCoE map to the port.
INTERFACE mode or FIBRE_CHANNEL mode
fabric map-name
Repeat this step to apply an FCoE map to more than one FC port.
For example:
Dell# interface fi 0/0
Dell(config-if-fc-0/0)# fabric SAN_FABRIC_A
3 Enable the port for FC transmission.
INTERFACE mode or FIBRE_CHANNEL mode
no shutdown
You can apply a DCB or FCoE map to a range of Ethernet or Fibre Channel interfaces by using the interface range command; for
example:
Dell(config)# interface tengigabitEthernet 1/12 - 23 , tengigabitEthernet 2/24 - 35
Dell(config)# interface fibrechannel 0/0 - 3 , fibrechannel 0/8 - 11
Enter the interface range keywords then an interface type and port range. A port range must contain spaces before and after the
dash. Separate each interface type and port range with a space, comma, and space as shown in the previous example.
Sample Conguration
The following are DCB, VLAN, and FCoE conguration examples.
Congure a DCB Map with PFC and ETS Settings.
Dell(config)# dcb-map SAN_DCB_MAP
Dell(config-dcbx-name)# priority-group 0 bandwidth 60 pfc off
Dell(config-dcbx-name)# priority-group 1 bandwidth 20 pfc on
Dell(config-dcbx-name)# priority-group 2 bandwidth 20 pfc on
Dell(config-dcbx-name)# priority-group 4 strict-priority pfc off
Dell(conf-dcbx-name)# priority-pgid 0 0 0 1 2 4 4 4
