Obvious may add an interface is not enough, you can have four interfaces aggregated in the bond, but there is still no flow without a link. To add even more chaos, both the physical and virtual interfaces are mentioned in the sentence preceding the one which Rafael mentions. That said, what about something like following? Failover allows traffic to continue to flow if at least one aggregated network interface has link established. -- Ondra Knezour
