1. ) A method of shutting down at least some network elements of an Ethernet network, comprising the steps of:

  • receiving (20), in a network element (2-9) a first shutdown binary signal, a first value of which commands to shutdown a network element, and the second value of which authorizes to restart a network element;

    detecting (20) the value of said shutdown signal;

    then propagating a shutdown to a downward network element by generating a second shutdown signal, if the first signal has its first value;

    characterized in that, for commanding a shutdown of at least some functions of said network element, it further comprises the steps of;

    assigning flags respectively to the ports of said network element, the value of a flag assigned to a port authorizing or forbidding the shutdown of this port, and the propagation of the shutdown via this port,checking flags that have been previously assigned and then executing the shutting down (22) and the propagation of the shutdown only for each port that has been assigned a flag authorizing the shutdown of this port, when this network element detects the presence of the first value of said first shutdown signal.
