Abstract
The invention relates to a switching node comprising a dynamic address table in a data network, in addition to a method for creating a dynamic address table of this type for a switching node. The method comprises the following steps: receipt of a first data message with a source address at a port of the switching node; entry of the source address, details of the port and a counter initial value in a line of the address table that is assigned to the source address as the target address, whereby the current counter value indicates the validity of the entry and the current counter value is modified, if a second data message with the source address as the target address is received and the entry is valid.
