Implementación de Ping MIB
Contenido
Introducción
El Grupo Ping es parte de la MIB propietaria de Cisco en la rama de administración de Cisco (.1.3.6.1.4.1.9.9.16.). El grupo de ping se puede utilizar para configurar, realizar y recuperar la actividad del protocolo de mensajes de control de Internet (ICMP) entre dispositivos remotos desde una estación de administración.
