Abstract: A group of network devices, such as Ethernet switches, are logically configured as a single cluster, with one commander device and one or more member devices. Each network device capable of belonging to a cluster transmits data packets containing cluster capability information to its neighbors. Each network device capable of belonging to a cluster that receives data packets containing cluster capability information maintains a database containing information about its cluster-capable neighbor devices. The commander device of a cluster is the point-of-contact through which the cluster is managed. The commander device maintains a database of neighbors of the entire cluster. Upon user request, the commander device displays a list of cluster neighbors and notes which ones may be added to the cluster. When the user adds a device to the cluster, that device immediately sends its database of discovered neighbors to the commander device.
