Overview
Ethernet link aggregation, most often simply called link aggregation, aggregates multiple physical
Ethernet links into one logical link to increase link bandwidth beyond the limits of any one single link.
This logical link is called an aggregate link. It allows for link redundancy because the member physical
links can dynamically back up one another.
As shown in Figure 1-1 , Device A and Device B are connected with three physical Ethernet links. These
physical Ethernet links are aggregated into an aggregate link, Link aggregation 1. The bandwidth of this
aggregate link can be as high as the total bandwidth of these three physical Ethernet links.
