./modules/ipi-install-configuring-host-dual-network-interfaces-in-the-install-config.yaml-file.adoc:<12> Sets the preferred port of the bonding interface. The bond uses the primary device as the first device of the bonding interfaces. The bond does not abandon the primary device interface unless it fails. This setting is particularly useful when one NIC in the bonding interface is faster and, therefore, able to handle a bigger load. This setting is only valid when the bonding interface is in active-backup mode (mode 1) and balance-tlb (mode 5).

 ./modules/agent-install-sample-config-bond-sriov.adoc:<12> Sets the preferred port of the bonding interface. The primary device is the first of the bonding interfaces to be used and is not abandoned unless it fails. This setting is particularly useful when one NIC in the bonding interface is faster and, therefore, able to handle a bigger load. This setting is only valid when the bonding interface is in `active-backup` mode (mode 1) and `balance-tlb` (mode 5).
