13.1. Managing Network Adapters on Physical Server

13.1.1. Listing Adapters

The Network Adapters screen displays a list of network interface cards (NICs) and VLAN adapters currently available on the physical server.

To access the screen, go to Infrastructure > physical server > Network tab. The information on the network adapters is presented in the table having the following columns:

Column Description
Interface The name assigned to the network adapter (e.g. physical adapter eth0, VLAN eth0.1).
Type Indicates whether it is a real physical adapter (Physical) or a VLAN adapter created on the basis of a physical adapter (VLAN).
VLAN ID The ID assigned to the VLAN adapter. Relevant for VLAN adapters only.
Virtual Network The name of the virtual network, if any, that is associated with this network adapter.
IP Addresses

The IP addresses assigned to the network adapter.

Note

To assign IP addresses and other network parameters to the adapter, you can use standard Linux utilities (for example, ip).

MAC Address The MAC address of the network adapter.

Note

To learn more about the notion of virtual networks and their relation to physical adapters, VLAN adapters, and virtual environments, please refer to the Managing Virtual Networks section.

To facilitate your working with network adapters, you can:

  • Configure the number of columns to be displayed in the Network Adapters table. To this effect, click the Select Columns link and clear the check boxes near the column name(s) that you wish to hide.
  • Modify the number of network adapters simultaneously displayed in the Network Adapters table by clicking the 10, 20, 40, or 80 link at the top of the table.

Available Operations

  • Remove an existing VLAN adapter. To do this, tick the check box near the corresponding adapter and click Delete.
  • Create a new VLAN adapter. To do this, click New VLAN Interface at the top of the Network Adapters table.

13.1.2. Viewing Physical Adapter Properties

The Physical Interface screen provides the key information on the physical adapter that you have selected on the Network tab of the physical server dashboard:

Column Description
Interface The name assigned to the network adapter (e.g. eth0).
Type Indicates that it is a physical adapter (Physical).
Virtual Network

The name of the virtual network, if any, associated with the network adapter.

Note

To learn more about virtual networks and their relation to physical adapters, VLAN adapters, and virtual environments, please refer to Managing Virtual Networks.

IP Addresses The IP addresses assigned to the network adapter.
MAC Address The MAC address of the network adapter.

The Configure button allows you to connect this physical network adapter to any of the available virtual networks. To assign IP addresses and other network parameters to the adapter, you can use standard Linux utilities (for example, ip).

13.1.3. Connecting Physical Adapter to Virtual Network

The Configure screen allows you to connect the physical network adapter existing on the physical server to any of the available virtual networks. This screen can be accessed by clicking the Network tab on the physical server dashboard, then clicking the name of the network adapter you wish to join to a virtual network, and clicking Configure.

On this screen, you can connect the physical network adapter to a virtual network (and, consequently, to the virtual environments joined to this virtual network) by selecting the name of the corresponding virtual network on the drop-down menu in the Network field. If you do not want to connect the adapter to a virtual network, select Not Assigned on the drop-down menu.

After deciding on the virtual network, click the Submit button.

Note

To assign IP addresses and other network parameters to the adapter, you can use standard Linux utilities (for example, ip).

13.1.4. Creating VLAN Adapters on Physical Servers

The New VLAN Interface screen allows creating new virtual local area network (VLAN) adapters on the basis of physical servers. You can use these adapters later to connect your virtual environments to the corresponding virtual local area networks. To access this screen, click New VLAN Interface.

To create a new VLAN adapter, fill out these fields:

  • VLAN Tag (mandatory). The ID that will be assigned to the new VLAN. Any integer value from 1 to 4094. The VLAN ID will be displayed in its name. If you choose the IDs “1” and “2” for the VLAN with the base interface “enp0s5”, their IDs will be “enp0s5.1” and “enp0s5.2” respectively.
  • Base Interface. The physical network adapter on the physical server to bind the VLAN to.
  • Assign Virtual Network (optional). The virtual network on the physical server to connect the VLAN adapter to. Virtual networks need to be created separately on the Infrastructure > <physical server> > Network tab > Virtual Networks subtab.

After entering the necessary information, click Submit to create the VLAN adapter. The newly created VLAN will be displayed on the Network Adapters screen.

13.1.5. Viewing VLAN Adapter Properties

The VLAN Interface screen provides the key information on the VLAN adapter that you have selected on the Network tab of the physical server dashboard:

Column Description
Interface The name assigned to the network adapter (e.g. eth0.1).
Type Indicates that it is a VLAN adapter created on the basis of a physical adapter (VLAN).
VLAN ID The ID assigned to the VLAN adapter.
Virtual Network

The name of the virtual network, if any, associated with the network adapter.

Note

To learn more about the notion of virtual networks and their relation to physical adapters, VLAN adapters, and virtual environments, please refer to Managing Virtual Networks.

IP Addresses The IP addresses assigned to the network adapter.
MAC Address The MAC address of the network adapter.

The Configure button allows you to connect this VLAN adapter to any of the available virtual networks. To assign IP addresses and other network parameters to the adapter, you can use standard Linux utilities (for example, ip).

13.1.6. Connecting VLAN Adapter to Virtual Network

The Configure screen allows you to connect the VLAN adapter existing on the physical server to any of the available virtual networks (and, consequently, to the virtual environments joined to this virtual network) by selecting the name of the corresponding virtual network on the drop-down menu in the Network field. If you do not wish the adapter to be joined to any virtual network, select Not Assigned on the drop-down menu.

After deciding on the virtual network, click Submit.

Note

To assign IP addresses and other network parameters to the adapter, you can use standard Linux utilities (for example, ip).
