Knowledge Base article:

摘要

Excessive Collisions 性能规则收集用于报告的数据。

原因

以下是通过 SNMP GET 查询到的对象标识符 (OID) 的详细信息

对象

OID

描述

dot3StatsExcessiveCollisions

.1.3.6.1.2.1.10.7.2.1.9

由于冲突过多而导致在特定端口上传输失败的帧的计数。当接口在全双工模式下工作时，此计数器不会增加。

发生这种情况的原因有：

解决方法

以下是一些基本故障排除步骤

检查设备的电缆连接。

对设备执行任何特定于供应商的硬件测试以确定设备的硬件是否正常工作

提高监视器的阈值。这将允许更好地调整对环境的应用。应注意，不要将阈值提高太多，否则会导致遗漏重要事件。
