Information About Virtual Fibre Channel (VFC) Interfaces
Fibre Channel over Ethernet (FCoE) allows Fibre Channel and Ethernet traffic to be carried on the same
physical Ethernet connection between the switch and the servers.
The Fibre Channel portion of FCoE is configured as a virtual Fibre Channel interface. Logical Fibre Channel
features (such as interface mode) can be configured on virtual Fibre Channel interfaces.
A virtual Fibre Channel (vfc) interface must be bound to an interface before it can be used. The binding is to
a physical Ethernet interface when the converged network adapter (CNA) is directly connected to the switch
or port channel when the CNA connects to the Fibre Channel Forwarder (FCF) over a virtual port channel
(vPC).
VF Port
A virtual fabric (VF) port in an FCoE network acts as a fabric port that connects to a peripheral device (host
or disk) operating as an N port. A VF port can be attached to only one N port.
