Overview of Link Aggregations

Link aggregation is a method to combine several physical datalinks on a system to improve the bandwidth for applications. These physical datalinks are configured together as a single logical unit to increase the throughput of network traffic and to achieve high availability at the datalink layer.

You can include any link aggregation that is listed in the available NICs as an individual interface by using Oracle Enterprise Manager Ops Center. You can also display the details of both trunk and DLMP aggregation by using Oracle Enterprise Manager Ops Center. For more information about the Oracle Enterprise Manager Ops Center, see http://www.oracle.com/pls/topic/lookup?ctx=oc122&id=OPCCM.

The following figure shows an example of a simple link aggregation configured on a system.

Figure 2-1  Link Aggregation Configuration

The illustration shows an aggregation aggr1 that consists of three underlying datalinks, net0, net1, and net2. These datalinks are dedicated to serve the traffic that traverses the system through the aggregation. The underlying links are hidden from external applications. Instead, the logical datalink aggr1 is accessible.
