ENode End Node or FCoE node
FC Fibre Channel
FC ID A 3-byte address used by FC to identify the end points
FC Map A 3-byte prex congured per VLAN, used to frame FCoE MAC address
FCF Fibre Channel Forwarder
FCoE Fibre Channel over Ethernet
FCoE MAC Unique MAC address used to identify an FCoE session. This is a combination of FC ID and FC Map.

Virtual fabric
Virtual fabrics (vfabric) divide a physical fabric into logical fabrics. Manage each vfabric independently. The fabric ID identies each vfabric.
You can congure only one vfabric in F_Port mode and multiple vfabrics in NPG mode. F_Port and NPG modes are mutually exclusive.
If you have already congured a vfabric in F_Port mode, while conguring vfabrics in NPG mode, disable F_Port mode. When you disable
F_Port mode, the existing vfabric is removed and you must congure new vfabrics in NPG mode. If you are moving from NPG mode to
F_Port mode, disable NPG mode and create the new vfabric in F_Port mode.
Zoning allows you to increase network security by partitioning the devices connected to the vfabric into subsets. Partitioning restricts
unnecessary interactions between the members of vfabric. For more information, see Fibre Channel zoning.
After conguring a vfabric ID, you can create a name, associate a VLAN to carry trac to the vfabric, congure FCoE parameters,
congure the default zone, and activate the zoneset.
NOTE
: Do not associate a VLAN that is already in use as a vfabric VLAN.
To congure a vfabric in F_Port mode:
1 Congure a vfabric using the vfabric fabric-ID command in CONFIGURATION mode. The switch enters vfabric
CONFIGURATION mode
2 Associate a VLAN ID to the vfabric with the vlan vlan-ID command.
3 Add an FC map with the fcoe fcmap fc-map command.
4 Activate a zoneset using the zoneset activate zoneset-name command.
5 Allow access to all logged-in members in the absence of an active zoneset conguration using the zone default-zone permit
command. The logged-in members are the FC nodes that are successfully logged into the FC fabric, identied by the vfabric.
