Recently, while adding availability features to some of our AIX DLPARs (Dynamic Logical PARtitions), i went through this very interesting (and well written) reading which explain why and how to use, deploy and configure properly some of the very nice network features on the AIX operating system: EtherChannel and Network Interface Backup. In short, EtherChannel represent a network port aggregation technology that allow multiple Ethernet adapters to create a single pseudo-Ethernet device. In its second form, known as Network Interface Backup, it protects against network-SPOF by providing failure detection and failover mechanism.
