Abstract
There is described a network having redundancy properties, an Ethernet switch, and a method for configuring the network. At least two network segments which are formed with a plurality of Ethernet switches are connected to one another by means of a redundant connection comprising at least two coupling channels. During configuration, a programming device stores a logic name for the redundant connection in the respective memory of associated coupling devices. In a network startup phase, said coupling devices determine the respective other connection partner associated with the same redundant connection by distributing special messages in which they enter the logic name of the redundant connection. They use an order criterion to determine which coupling channel is active and which coupling channel is deactivated during trouble-free operation.
