Parameters
interface-type interface-number: Specifies an interface by its type and number. The interface type can
only be one of the following:
Layer 2 Ethernet interface.
•
Layer 2 aggregate interface.
•
S-channel interface.
•
• S-channel aggregate interface.
mac mac-address: Specifies the bound peer FCoE MAC address, in the format of XXXX-XXXX-XXXX and
six bytes in length.
Usage guidelines
To make a VFC interface work, bind it to a Ethernet interface. The VFC interface then sends and receives
packets through the Ethernet interface.
To use one physical link to carry multiple VFC interfaces, you must bind these VFC interfaces to different
peer FCoE MAC addresses. However, you can bind them to one Ethernet interface. The FCoE MAC
address identifies the device that communicates with a VFC interface. For a point-to-multipoint network,
the FCoE MAC address is required. For a point-to-point network, the FCoE MAC address is optional.
You can use the display fcoe command to display the FCoE MAC address of a switch. You can display
the FCoE MAC address of an ENode through some software or the NMS.
A VFC interface can be bound to only one Ethernet interface and one FCoE MAC address.
An Ethernet interface can be bound to multiple VFC interfaces, but an FCoE MAC address can be bound
to only one VFC interface.
To successfully bind a VFC interface to a Layer 2 Ethernet interface, make sure the Layer 2 Ethernet
interface is FCoE capable.
When you bind a VFC interface to a Layer 2 aggregate interface, follow these restrictions and
guidelines:
• To successfully bind a VFC interface to a Layer 2 aggregate interface, make sure all member ports
of the Layer 2 aggregate interface are FCoE capable. Also, make sure new member ports of the
Layer 2 aggregate interface are FCoE capable. Otherwise, FCoE traffic might be blocked.
The binding to a Layer 2 aggregate interface does not take effect when you perform the following
•
tasks:
Bind one VFC interface to the Layer 2 aggregate interface.
Bind another VFC interface to a member port of the Layer 2 aggregate interface.
Enabling EVB on a Layer 2 Ethernet interface or Layer 2 aggregate interface disables the interface from
forwarding FCoE traffic. To enable such an interface to forward FCoE traffic, you must create an
S-channel interface or S-channel aggregate interface and bind a VFC interface to the created interface.
