Abstract

L'invention concerne un dispositif élément de réseau et un procédé pour commander à un dispositif élément de réseau de rejoindre un réseau. Dans le procédé : un dispositif élément de réseau transmet un premier paquet de protocole à un dispositif élément de réseau de nœud de niveau supérieur, le premier paquet de protocole ne contenant pas d'informations de réseau local virtuel (VLAN) d'un canal de gestion de réseau ; le dispositif formant élément de réseau reçoit un second paquet de protocole envoyé par le dispositif élément de réseau de nœud de niveau supérieur d'après le premier paquet de protocole, et établit une connexion de communication avec un serveur de gestion de réseau d'après les informations VLAN du canal de gestion de réseau contenues dans le second paquet de protocole, les informations VLAN du canal de gestion de réseau contenues dans le second paquet de protocole étant les informations VLAN fournies par le dispositif élément de réseau de nœud de niveau supérieur au dispositif élément de réseau de nœud de niveau suivant, pour établir un canal de gestion de réseau. Dans la présente invention, le dispositif élément de réseau obtient automatiquement les informations VLAN du canal de gestion de réseau, du dispositif élément de réseau de nœud de niveau supérieur connecté à l'élément de réseau dispositif, en tant que les informations VLAN du canal de gestion de réseau du dispositif élément de réseau, et établit un canal de gestion de réseau d'après les informations VLAN du canal de gestion de réseau correspondant, permettant ainsi au dispositif élément de réseau d'établir une connexion de communication avec le serveur de gestion de réseau.
