1. A method of monitoring data transmitted between a source node and a destination node in a switched network, the network comprising a plurality of network switches with at least one network switch connected between the source and destination nodes through which the data between the source and destination nodes passes, each network switch including a connection table, the method comprising steps of:

  • (a) identifying one network switch connected between the source and destination nodes to be an originating switch;

    (b) identifying one network switch to be a probe switch, the probe switch having a probe attached to a probe port;

    (c) identifying all intermediate network switches connected in a path between the originating switch and the probe switch; and

    (d) configuring the originating switch, the probe switch and all intermediate network switches to pass data transmitted from at least one of the source node and the destination node to the probe port of the probe switch.
