Configuring VFC interfaces
A VFC interface can connect to an ENode, or a switch operating in FCF, NPV, or Transit mode.
A VFC interface can operate in E mode, F mode (the default), or NP mode.
A VFC interface is a virtual logical interface. It implements the functionality of an FC interface. To make
a VFC interface work, bind it to a physical Ethernet interface. The switch encapsulates the FC frames on
the VFC interface in FCoE frames and transmits the frames over the Ethernet link.
To avoid FCoE packet loss in the Ethernet, you must perform the following tasks on the Ethernet interface
bound to the VFC interface:
• Configure data center bridging exchange (DCBX), priority-based flow control (PFC) in auto mode,
and enhanced transmission selection (ETS) on the Ethernet interfaces that connect the switch to
servers.
• Configure DCBX and PFC in auto mode on the Ethernet interfaces that connect the switch to disk
devices.
• Forcibly enable PFC on the Ethernet interfaces that connect the switch to other switches.
For more information about DCBX, PFC, and ETS, see Layer 2—LAN Switching Configuration Guide.

Command Remarks
1. Enter system view.
system-view N/A
2. Create a VFC interface and
enter its view.
interface vfc interface-number N/A
3. Configure the VFC interface
mode.
fc mode { e | f | np }
By default, a VFC interface operates
in F mode.
• An FCF supports E and F modes.
• An NPV switch supports F and NP
modes.
4. Bind the VFC interface to the
specified Ethernet interface.
bind interface interface-type
interface-number [ mac
mac-address ]
By default, no Ethernet interface is
bound to a VFC interface.
The VFC interface sends and receives
packets through the Ethernet interface
bound to it.
5. Assign the VFC interface to
the specified VSAN as a
trunk port.
port trunk vsan vsan-id
By default, a VFC interface does not
belong to any VSAN as a trunk port.
6. (Optional.) Configure a
description for the VFC
interface.
description text
By default, the description of an
interface is interface name Interface,
for example, Vfc1 Interface.
