摘要： A method and apparatus of a device that monitors a link for a slow link flap event is described. In an exemplary embodiment, a device detects a link flap in a current time interval of a link that couples a pair of devices. In addition, the current time interval is one of a plurality of time intervals that are used to monitor the link for a slow link flap. Furthermore, a slow link flap event results from detecting a maximum number of link flap violations over the plurality of time intervals. The device additionally increments a number of detected link flaps for the current time interval. If the number of detected link flaps for the current time interval is greater than a maximum number of slow link flap violations, the device marks the current time interval as a possible slow link flap interval. In addition, if the total number of intervals among the current time interval and one or more preceding time intervals, which are marked as possible slow flap intervals, equals the maximum number of slow flap intervals, the device brings the link down.
摘要翻译： 描述了监视慢链接折翼事件的链接的装置的方法和装置。 在示例性实施例中，设备在耦合一对设备的链路的当前时间间隔中检测链路瓣。 此外，当前时间间隔是用于监视慢链接折叠的链接的多个时间间隔之一。 此外，慢链接翻盖事件是由于检测多个时间间隔中的链接挡片违反的最大数量而产生的。 该设备另外增加当前时间间隔中检测到的链路襟翼数量。 如果当前时间间隔检测到的链路襟翼数量大于最大缓冲链接襟翼数量，则设备将当前时间间隔标记为可能的慢链接襟翼间隔。 另外，如果当前时间间隔和标记为可能的慢片间隔的一个或多个先前时间间隔之间的间隔的总数等于缓慢片段间隔的最大数量，则设备将链接断开。
