Embodiments of the invention relate to virtual link aggregation. One embodiment includes a system including a first aggregation switch. A second aggregation switch is connected to the first aggregation switch with a first link. An access switch is connected to the first aggregation switch with a second link and the second aggregation switch with a third link. The first access switch establishes a first virtual link with the first aggregation switch and the second aggregation switch. A first detection module is connected with the first aggregation switch. The first detection module maintains multiple networking ports in a first disabled state, determines a link-status of the first link, and activates a first event upon the determination of a first status indication for the first link, and switches at least one of the multiple networking ports to a first enabled state upon detecting the first event. |
