NOTE: In each FCoE map, the fabric ID, FC-MAP value, and FCoE VLAN must be unique. To access
one SAN fabric, use one FCoE map. You cannot use the same FCoE map to access different fabrics.
When you configure an S5000 as an NPG, FCoE transit with FIP snooping is automatically enabled and
configured using the parameters in the FCoE map applied to server-facing Ethernet and fabric-facing FC
interfaces (refer to FIP Snooping on an NPIV Proxy Gateway).
After you apply an FCoE map on an FC port, when you enable the port (using the no shutdown
command), the NPG starts sending FIP multicast advertisements on behalf of the FC port to downstream
servers to advertise the availability of a new FCF port on the FCoE VLAN. The FIP advertisement also
contains a keepalive message to maintain connectivity between a SAN fabric and downstream servers.
Applying an FCoE Map on Server-Facing Ethernet Ports
You can apply multiple FCoE maps on an Ethernet port or port channel.
When you apply an FCoE map on a server-facing port or port channel:
• The port is configured to operate in hybrid mode (accept both tagged and untagged VLAN frames).
• The associated FCoE VLAN is enabled on the port or port channel.
When you enable a server-facing Ethernet port, the servers respond to the FIP advertisements by
performing FLOGIs on upstream virtualized FCF ports. The NPG forwards the FLOGIs as fabric discovery
(FDISC) messages to a SAN switch.
1. Configure a server-facing Ethernet port or port channel with an FCoE map.
CONFIGURATION mode
interface {tengigabitEthernet slot/port | fortygigabitEthernet slot/port |
port-channel num}
2. Apply the FCoE/FC configuration in an FCoE map on the Ethernet port.
INTERFACE mode or INTERFACE PORT_CHANNEL mode
fcoe-map map-name
Repeat this step to apply an FCoE map to more than one port.
For example:
Dell# interface tengigabitEthernet 0/0
Dell(config-if-te-0/0)# fcoe-map SAN_FABRIC_A
Dell# interface port-channel 3
Dell(config-if-po-3)# fcoe-map SAN_FABRIC_A
Dell# interface fortygigabitEthernet 0/48
Dell(config-if-fo-0/0)# fcoe-map SAN_FABRIC_A
3. Enable the port for FCoE transmission using the map settings.
