¿Qué es el contador de control de pausa??

The Pause control counter indicates the number of times the router requests another router to slow the traffic. Por ejemplo, two routers, Router A and Router B, are connected through a link with flow control enabled. If Router B faces a traffic burst, Router B sends a Pause output packet to inform Router A to slow the traffic because the link is oversubscribed. At that time, Router A receives a Pause input packet that informs it of the request sent by Router B. Pause output / input packets are not a problem or an error. They are simply flow control packets between two devices.
