Ejemplo: configuración de recursos compartidos en interfaces Ethernet IQ2
Para el tráfico de entrada en la interfaz física, unidades de interfaz ge-1/2/3lógica, 2y 3 para compartir un conjunto de recursos del programador-formador, definidos por el perfil s1de control de tráfico.1 Unidades 4de interfaz lógica , y 6 comparten otro conjunto de recursos del programador-formador, 5definidos por el perfil s1de control de tráfico.
Para el tráfico de salida en la interfaz física , unidades de interfaz ge-1/2/3lógica , y 3 comparten un conjunto de recursos del programador-formador, 2definidos por el perfil s2de control de tráfico.1 Unidades 4de interfaz lógica , y 6 comparten otro conjunto de recursos de formador de programador, 5definidos por el perfil s2de control de tráfico .
Para cada interfaz física, la shared-instance instrucción crea un conjunto de recursos que se compartirán entre las unidades , , y otro conjunto de recursos que se compartirán entre las unidades 14, 25, y 3 6. Las velocidades de modelado de entrada y salida se configuran en el nivel de interfaz física, lo que demuestra la capacidad de modelado jerárquico de la PIC IQ2 DE Gigabit Ethernet.
