Afficher l'ensemble des informations (optional: displays information for all not null interfaces ) -t seconds (optional: 1 second) Les options -n et -p se basent sur le seuil 'Warning number Threshold' pour afficher les résultats. Pour -p, ceci évite de remonter des alertes si très peu de paquets ont transités par l'interface, Ex 1/2 --> 50% L'option -p peut être accompagnée de l'option -W pour fixer le nombre de paquet pour lequel le pourcentage doit remanter en alerte. Cette option (-W) est positionnée à 30 par défaut. Remarks: * Checks input/output multicast and broadcast traffic * Checks one, more or all interfaces * Provides stats by percentage or integer values.
