This section describes how to update and modify a Bonding interface. There are two sections of the panel: Global Settings in order to configure the interface and Slaves to select the enabled slaves among the available ones.
Global Settings
In this section you can configure the following attributes on the bonding interface:
Name. The bonding interface name as stored in the system. Not editable.
MAC. The link-layer MAC address of the bonding interface. you can generate a new random valid MAC address clicking in the generate random MAC button or configure a new custom MAC address. In the case of changing the MAC for a custom MAC address, it should be used with caution in order to avoid MAC address duplication.
Each slave will share the MAC address with the bonding master and will restore its MAC address once the bonding is deleted.
IP Address. The network-layer IP address of the bonding. It supports IPv4 and IPv6. This field is mandatory and the Netmask field must be also set if DHCP is disabled.
Netmask/CIDR. The subnet mask of the bonding. It supports Network mask format or CIDR (0 to 32 bits) when using IPv4 or only CIDR format (0 to 128 bits) when using IPv6. This field is mandatory and the Address field must be also set if DHCP is disabled.
Gateway. Default gateway used by the bonding.
Mode. Bonding mode set when creating the bonding interface. Not editable.
Alias. Interface alias, it identifies the interface with an alias that can be easily accessed when configuring a farm or any other service.
DHCP. Enable or disable the Dynamic Host Configuration Protocol (DHCP) for the bonding interface. If enabled it won’t allow static IP address configuration and will require a DHCP server running and reachable.
IPv4 and IPv6 stacks are supported, take into account that the Netmask and Gateway must be configured in the same stack than the IP.
Slaves
The configure slaves panel allows to make changes in regards to the Available NICs in the system and the Enabled Slaves that will be used to take part in a given bonding interface.
Select the interface or interfaces you want to add or remove from the bonding interface and click on the arrow to apply the changes, you can also add all the available NICs as slaves with the double arrows button, you can also delete all slaves but one. Notice that there must be at least one slave in the bonding.
Once all the required changes are done, press the Submit button to apply the new changes. Once the configuration is updated the bonding interface is brought up.
