Abstract: The invention relates to a method for operating a network, wherein the network comprises a plurality of network devices having ports, the network devices being connected to one another for transmitting data via cables which are each inserted into a respective port, wherein each port has signaling means which can be switched between at least two signaling states. The invention is characterized in that all signaling means of those ports of the network devices, which have the same configuration, are brought into an associated detectable signaling state.

Abstract: A method of operating a network that has network infrastructure devices (1, 2) that have multiple ports and that are connected or are connectable to each other for data transmission via respective cables inserted into the ports that each have a signaling means that can be switched between at least two signaling states, characterized in that a signaling means of a port of the one network infrastructure device (1) and a signaling means of a port of another network infrastructure device (2) are brought into a signaling state indicating that they belong together so that it is easy to determine that the ports belong together.

Abstract: The invention relates to a method for redundantly and reactionlessly connecting networks to each other, such as communication networks, particularly Ethernet networks, wherein there is a plurality of network devices which communicate and exchange data with each other via data lines in the network which has at least one, preferably a plurality of network segments, characterized in that at least more than one RSTP protocol instance is implemented on the network devices for coupling network segments so that one network segment can be connected per RSTP protocol instance.
