Common Management Information Protocol

Common Management Information Protocol

El Protocolo de administración de información común (CMIP) es un protocolo de administración de red que define la comunicación entre las aplicaciones de administración de red y la gerencia de los agentes. CMIP se basa en el modelo OSI (Open Systems Interconnection) y es definido por la serie de recomendaciones ITU-T X.700.

CMIP define la información de la gerencia en términos de objetos administrados y permite tanto la modificación como las acciones sobre objetos gestionados. Se describen usando GDMO y los objetos son identificados por un nombre distinguido (DN), similar en concepto al directorio X.500.

Los NMS pueden realizar las operaciones siguientes:

  • CREATE - crear una instancia de un objeto gestionado.
  • DELETE - suprimir una instancia de un objeto gestionado.
  • GET - solicitar el valor de un atributo de una instancia de un objeto gestionado.
  • CANCEL_GET - cancelar una petición de GET en curso.
  • SET - fijar el valor de un atributo de una instancia de un objeto gestionado.
  • ACTION - solicitar una acción para ocurrir según lo definido por el objeto gestionado.

El agente administrador puede realizar esta operación:

  • EVENT_REPORT - enviar notificaciones o alarmar a los NMS.

CMIP también proporciona buena seguridad (autorización de la ayuda, control de acceso y registros de la seguridad) y un reporte flexible de las condiciones inusuales de la red.
