Remarques

ICMP est un ensemble de messages à utiliser avec le protocole Internet version 4 (IPv4). ICMP est utilisé par les nœuds IPv4 pour signaler les erreurs rencontrées dans le traitement des paquets de données et pour effectuer d’autres fonctions de couche Internet. ICMP version 4 est définie dans IETF RFC 792.

Pour plus d’informations sur les statistiques de trafic ICMP version 4 disponibles pour les applications, consultez la IcmpV4Statistics documentation de classe. Notez que l’objet IcmpV4Statistics retourné par cette méthode reflète les statistiques à partir du moment où l’objet est créé. Ces informations ne sont pas mises à jour dynamiquement.
