The invention relates to a switching node (100) and to a method for operating a switching node (100) in a data network. Said method comprises the following steps: receipt of a data message (118) at a first port (102) of the switching node (100); verification (112) of whether the data message (118) is a broadcast data message. If said message is not a broadcast data message, the source address of the data message (118) is passed to a dynamic address table (110) and if said message is a data broadcast data message, the data message (118) is forwarded via the additional ports (104, 106, 108) of the switching node (100).
