Bond Interfaces Settings

Use the Bond Interfaces settings to configure user-defined bond interfaces.

Under Network > Interfaces > Bond Interfaces, you can add a new or edit an existing bond interface.

The Bond Interface panel displays the following information and allows you to configure the following elements:

Input field	Description
I/0	A slider switch indicates whether the bond interface is active (I) or inactive (0). Click the slider switch to change the status of the bond interface. New bond interfaces are activated by default.
Name	Displays the name of the bond interface. The name is filled in automatically. Bond interfaces are numbered in the order they are created, starting with bond0.
Hardware Address	Displays the hardware address (MAC address) of the bond interface.
Used by	Display the network components (e. g. connections, other interfaces, etc.) that use the bond interface.
Mode	From the drop-down list, select the mode of operation for the bond interface, specifying how the multiple Ethernet interfaces are to be aggregated. The option is set to IEEE 802.1AX (LACP, Direct connection) by default, but you can adjust the settings to the other values as necessary: Balance - Round-Robin (Trunk, Direct connection) – This mode provides load balancing and high availability. Packets are transmitted in sequential order from the first available aggregated Ethernet interface through the last, then continuing with the first aggregated Ethernet interface again. Active-Backup (Bridge) – This mode provides high availability only. Data is transmitted and received by the active Ethernet interface (i. e. the first Ethernet interface in the list) only as long as it is not faulty. When the first Ethernet interface fails, the next Ethernet interface in the list is used to transmit and receive data. If the original interface becomes available again, the connection remains on the interface which took over communication. Balance - XOR (Trunk, Direct connection) – This mode provides load balancing and high availability. Packets are transmitted on all Ethernet interfaces. A simple algorithm (layer2+3 XOR) is applied to decide which Ethernet interface is used to transmit the data. Broadcast (Trunk, Direct connection) – This mode provides high availability only. Packets are transmitted simultaneously on all Ethernet interfaces. IEEE 802.1AX (LACP, Direct connection) – This mode provides load balancing and high availability by using the LACP (Link Aggregation Control Protocol) standard. Packets are transmitted on all Ethernet interfaces. A simple algorithm (layer2+3 XOR) is applied to decide which Ethernet interface is used to transmit the data. Balance - TLB (Bridge) – This mode provides load balancing and high availability. In addition to the simple selection algorithm (layer 2+3 XOR), the current load of the Ethernet interface is taken into account when deciding which Ethernet interface is to be used to transmit the data. Balance - ALB (Bridge) – This mode provides load balancing and high availability. Data is received using ARP negotiation. In addition to the simple selection algorithm (layer 2+3 XOR), the current load of the Ethernet interface is taken into account when deciding which Ethernet interface is to be used to transmit the data.
Ports	Add the Ethernet interfaces that you want to aggregate into one logical link by clicking the input field. You can add as many available Ethernet interfaces as you like. Important: You can select only Ethernet interfaces that are not used by other interfaces or in any network connections. The selected Ethernet interfaces are displayed in a table at the bottom of the panel. To delete an element from the input field, click to the left of the entry.
MTU	Set the maximum size of each packet (in bytes). The maximum transmission unit can be any integer from 64 to 16384.

The buttons at the bottom right of the editor panel depend on whether you add a bond interface or edit an existing one. For a newly configured bond interface, click Create to add it to the list of available bond interfaces or Cancel to discard your changes. To edit an existing bond interface, click Save to save the reconfigured interface or Reset to discard your changes. You can click Close to shut the editor panel as long as no changes have been made on it.

Click Activate in the toolbar at the top of the desktop to apply your configuration changes.
