Abstract

A network device includes a first plurality of ports and a first plurality of communication links. Each port of the first plurality of ports communicates with a corresponding communication link of the first plurality of communication links. An adapter aggregates the first plurality communication links into a second plurality of aggregated links. The adaptor assigns a single media access control address to each aggregated link of the second plurality of aggregated links. A driver selects a first aggregated link of the second plurality of aggregated links as an active link based on a link quality of the first aggregated link. The driver sends and receives data over the first aggregated link using the single media access control address assigned to the first aggregated link. The driver selects a second aggregated link of the second plurality of aggregated links as the active link in response to the link quality of the first aggregated link being less than a link quality of the second aggregated link.
