Release Information

Statement introduced in Junos OS Release 12.3.

Description

Create an Ethernet interface on a compute node. An Ethernet interface connects one interface on the VSE device to the device running Junos OS.

On the VSE device, there are two sets of four ports for the VSE 1100 device and one set of four ports and one set of two ports for the VSE 2100 device. The set of four ports on the left side when you are facing the VSE device are onboard ports and the ports on the left are data or IOC ports. The onboard ports are interfaces named eth0 to eth3 going from leftmost to right as you face the device. The IOC ports are interfaces named eth4 to eth7 going from the rightmost to the leftmost. See Figure 2, which shows that interfaces eth3 and eth7 are next to each other in the middle of the device face (on a VSE 1100 device).

Configuration changes to network interfaces are nondestructive, that is, such changes do not require a reboot of the compute node. The exception to this is if it is a management interface. Changes to management interfaces are destructive and require a reboot of the compute node.

Options

enable-passthrough

Required for VT-d mode. Configure the Ethernet interface in VT-d mode.

If the Ethernet interface is configured for VT-d mode, the following constraints for the ethernet statement apply:

  • The management option must not be configured.
  • The interface cannot be part of a bridge interface.
  • The family and address options must not be configured.

Default: Not configured

ethernet ethernet-interface-name

Name of the Ethernet interface. The Ethernet interface name must be of the form eth#, where # can be any valid network interface number (for example, from eth0 to eth7 for a VSE 1100 device).

management

(Optional) Specifies the interface as the management interface of the compute node. There can be only one management interface per compute node. If there are more than one network interfaces, specify management for one of the network interfaces. Configuration changes to a management interface require a reboot of the compute node.

The remaining statements are explained separately.

Required Privilege Level

admin—To view this statement in the configuration.
