Adding a Virtual Interface

Use this procedure to configure a virtual interface for a host. This can be either a VLAN or an alias interface.

An alias interface is an additional IP address attached to an existing interface. An alias interface automatically inherits a MAC address from the interface it is attached to; therefore, you can create an alias without specifying a MAC address. The interface must be specified in a subnet with boot mode set to static.

Procedure

  1. In the {ProjectWebUI}, navigate to Hosts > All Hosts.

  2. Click Edit next to the host you want to edit.

  3. On the Interfaces tab, click Add Interface.

  4. Keep the Interface option selected in the Type list.

  5. Specify the general interface settings. The applicable configuration options are the same as for the physical interfaces described in [Adding_a_Physical_Interface_{context}].

    Specify a MAC address for managed virtual interfaces so that the configuration files for provisioning are generated correctly. However, a MAC address is not required for virtual interfaces that are not managed.

    If creating a VLAN, specify ID in the form of eth1.10 in the Device Identifier field. If creating an alias, use ID in the form of eth1:10.

  6. Select the Virtual NIC checkbox. Additional configuration options specific to virtual interfaces are appended to the form:

    • Tag: Optionally set a VLAN tag to trunk a network segment from the physical network through to the virtual interface. If you do not specify a tag, managed interfaces inherit the VLAN tag of the associated subnet. User-specified entries from this field are not applied to alias interfaces.

    • Attached to: Specify the identifier of the physical interface to which the virtual interface belongs, for example eth1. This setting is required.

  7. Click OK to save the interface configuration.

  8. Click Submit to apply the changes to the host.
