ABSTRACT:
A method and apparatus for securing a network from access by unauthorized end stations. A port in a multiport repeater can be disabled automatically upon detection of an unknown source address in a data packet. In addition, an interrupt signal is provided to the indicate the detection of an intruder. Further, the disabling of the port can be done substantially immediately to interrupt the re-transmission of a single packet. Alternatively, the disabling of a port can be done programmably after a predetermined number of intruder packets have been detected, or after the verification of packet integrity.
