Hola expertos de esta comunidad.
Querría saber cómo diagnosticar y que significan los contadores de las interfaces. Abajo pongo un ejemplo de una interfaz, ¿que significan los contadores CRC, runts, errors, giants, throttles u overruns? ¿Que significa si esos contadores aumentan? ¿Hay algún manual donde expliquen esos contadores y su significado?
