6.3. Configuring Host Networking

After you assign a host to a deployment role in a deployment, you can configure the network traffic that each network interface on the host carries. Network traffic types are divided amongst subnets in accordance with the options you select when you create a deployment.

6.3.1. Configuring Networking on a Host

Specify the network traffic carried by the network interfaces on a host.

Procedure 6.6. Configuring Networking on a Host

  1. Click OpenStack InstallerDeployments.
  2. Click the name of a deployment to open the details page for that deployment.
  3. Click the Hosts tab.
  4. Click the Assigned sub-tab.
  5. Select the check box for a host and click Configure Networks.
  6. Drag and drop subnets between the sections for network interfaces to change the network traffic carried by those interfaces.

  7. Optionally, configure a bond between two network interfaces:
    1. Click the bonding button for a network interface and click the name of a network interface to bond the two network interfaces.
    2. Select the bonding mode from the Bonding Mode list.
  8. Click Done.

6.3.2. Bonding Modes

The following table outlines the bonding modes that you can assign to bonded network interfaces.

Table 6.3. Bonding Mode

Bonding Mode Description   
balance-rr The packets in all inbound and outbound network traffic handled by the bond is transmitted sequentially through each of the network interfaces in the bond. For example, if there are two network interfaces in the bond, the first packet is handled by the first network interface, the second packet is handled by the second network interface, and the third packet is handled by the first network interface.   
active-backup One of the network interfaces in the bond is designated as the active network interface, and the other network interface is designated as a backup. Inbound and outbound network traffic are both handled only by the active network interface. Network traffic is only handled by the backup network interface when the active network becomes unavailable and the backup network interface becomes the active network interface.   
balance-xor Network traffic is handled by the network interfaces in the bond in accordance with an XOR formula. With this bonding mode, network traffic from a given source MAC address is always handled by the same destination MAC address in the network interface.   
broadcast All inbound and outbound network traffic is passed through all network interfaces in the bond.   
802.3ad All inbound and outbound network traffic is handled in accordance with aggregation groups that each have the same speed and duplex settings.   
balanced-tlb Inbound network traffic is handled by the current network interface. Outbound network traffic is distributed amongst the active network interfaces in the bond in accordance with the load on each network interface.   
balance-alb In addition to distributing outbound network traffic in a similar fashion to balance-tlb, inbound IPv4 network traffic is also distributed amongst the active network interfaces in the bond.
