Configuring Virtual Interfaces
This section describes the configuration of virtual interfaces on the Cisco Nexus 5000 Series switches.
It includes the following sections:
• Information About Virtual Interfaces, page 30-1
• Guidelines and Limitations, page 30-1
• Configuring Virtual Interfaces, page 30-2
• Verifying Virtual Interface Information, page 30-4
Information About Virtual Interfaces
Cisco Nexus 5000 Series switches support Fibre Channel over Ethernet (FCoE), which allows Fibre
Channel and Ethernet traffic to be carried on the same physical Ethernet connection between the switch
and the servers. For additional information about FCoE, see Chapter 29, “Configuring FCoE.”
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.
Note Virtual interfaces are created with the administrative state set to down. You need to explicitly configure
the administrative state to bring the virtual interface into operation.
Guidelines and Limitations
When configuring virtual interfaces, note the following guidelines and limitations:
• Each virtual Fibre Channel interface must be bound to an FCoE-enabled Ethernet interface. FCoE
is supported on 10-Gigabit Ethernet interfaces.
• Each virtual Fibre Channel interface is associated with only one VSAN.
• Any VSAN with associated virtual Fibre Channel interfaces must be mapped to a dedicated
FCOE-enabled VLAN.
• FCoE is not supported on private VLANs.
