La información de la red pública y privada se almacena en Oracle Cluster Registry (OCR).
$./oifcfg getif bondeth0 192.168.16.0 global public ib0 172.16.0.0 global cluster_interconnect
“cluster_interconnect” — Interfaz privada en Oracle Clusterware
El comando iflist consulta al sistema operativo para encontrar qué interfaces de red están presentes en este nodo.
El comando iflist muestra las interfaces disponibles que puede configurar con "setif".
El parámetro -p muestra el tipo de interfaz que puede ser PRIVADA, PÚBLICA o DESCONOCIDA
-n incluye la máscara de subred
