Abstract: Embodiments relate to synchronizing Internet Group Management Protocol (IGMP) leave processing in a system. One embodiment includes a system with a first access switch, a first virtual switch having a first timer, and a second virtual switch having a second timer. The first virtual switch and the second virtual switch are connected with the first access switch. The first access switch transmits an IGMP leave message to the first virtual switch. The first virtual switch transmits a synchronization message to the second virtual switch. The second virtual switch updates the second timer based on receiving the synchronization message.

Abstract: Embodiments of the invention relate to virtual link aggregation. One embodiment includes preventing network traffic loss upon rebooting of a first networking device based on: maintaining a first group of networking ports in a first disabled state, determining a link-status of a first link between the first networking device and a second networking device, activating a delay timer for delaying the rebooting of the first network device upon the determination of a first status indication for the first link, and switching at least one of the first group of networking ports to a first enabled state upon expiration of the delay timer.

Abstract: 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.
