Abstract

La présente invention concerne un procédé et un dispositif de de surveillance du fonctionnement de ports d’un commutateur d’un réseau de communication comprenant une pluralité de commutateurs, chaque commutateur comportant au moins un premier et un second ports, le premier port (P1) de chaque commutateur étant relié à un second port (P2) d’un autre commutateur, chaque commutateur émettant et recevant des données par l’intermédiaire des premier et second ports. Selon l’invention : - le commutateur dit premier commutateur (S1) génère une première trame (T1) de surveillance comportant une information indiquant si les trames émises par un second commutateur (S2) auquel la trame de surveillance est destinée sont correctement reçues et au moins une information indiquant si les trames émises par le premier commutateur à un troisième commutateur (S12) relié au premier port (P1) du premier commutateur (S1) sont correctement reçues par le troisième commutateur (S12), - le premier commutateur (S1) transfère la première trame de surveillance générée, par l’intermédiaire du second port (P2) du premier commutateur (S1), au premier port (P1) du second commutateur (S2) relié au second port (P2) du premier commutateur (S1). Fig. 2The present invention relates to a method and a device for monitoring the operation of ports of a switch of a communication network comprising a plurality of switches, each switch comprising at least a first and a second port, the first port (P1) of each switch being connected to a second port (P2) of another switch, each switch transmitting and receiving data via the first and second ports. According to the invention: - the switch called the first switch (S1) generates a first monitoring frame (T1) comprising information indicating whether the frames sent by a second switch (S2) to which the monitoring frame is intended are correctly received and at least one piece of information indicating whether the frames transmitted by the first switch to a third switch (S12) connected to the first port (P1) of the first switch (S1) are correctly received by the third switch (S12), - the first switch (S1) forwards the generated first monitoring frame, via the second port (P2) of the first switch (S1), to the first port (P1) of the second switch (S2) connected to the second port (P2) of the first switch (S1) .
