Users Guide

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 configured on the port and exported to downstream server CNA
ports.
Each Aggregator, with the 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.

CONFIGURATION
2
Apply the FCoE and FC fabric configurations in
an FCoE map to the port. Repeat this step to
apply an FCoE map to more than one FC port,
for example:
Dell# interface fi 0/9
Dell(config-if-fc-0/9)# fabric
SAN_FABRIC_A

Enable the port for FC transmission.

Important Points to Remember
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 range tengigabitEthernet 1/12 - 23 , tengigabitEthernet
2/24 - 35
Dell(config)# interface range fibrechannel 0/0 - 3 , fibrechannel 0/8 - 11
Enter the keywords interface range followed by 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 preceding examples.
Sample Configuration
1. Configure 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
