This section describes how to update and modify a Bonding interface. There are two sections of the panel: Global Settings: This is used to configure the interface. Slaves. Used to select the “slaves items” from the available slaves menu.
In this section you will configure the following attributes on the bonding interface:
Name. The bonding interface name as stored in the system. This is not editable.
MAC. The link-layer MAC address of the bonding interface. You may generate a new random valid MAC address by clicking on the “generate random MAC” button, or configure a new custom MAC address. In case of changing to a custom MAC address, it should be used with caution 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. The bonding mode set when creating a bonding interface. This is not editable.
Alias. Interface alias identifies the interface with an alias that can be easily accessed when configuring a farm or any other service.
DHCP. Enables or disables the Dynamic Host Configuration Protocol (DHCP) for the bonding interface. If enabled it won’t allow the static IP address configuration and will require a DHCP server that is running and is reachable.
IPv4 and IPv6 stacks are supported, taking into account that the Netmask and Gateway must be configured in the same stack as the IP.
The “configure slaves” panel allows making changes in regards to the Available NICs in the system, and the Enabled Slaves to be used in taking part in a given bonding interface.
Select the interface or interfaces you want to add or remove, and apply the changes. You may also add all the available NICs as slaves with the double arrows button. Notice that there must be at least one slave in the bonding.
Once all the required changes are done, click the Submit button. Once the configuration is updated the bonding interface is brought up.
