摘要

Excessive Collisions 閾值監視。

原因

透過 SNMP GET 查詢的物件識別碼 (OID) 詳細資料如下：

物件

OID

描述

dot3StatsExcessiveCollision

.1.3.6.1.2.1.10.7.2.1.9

因過度衝突而在特定介面上傳輸失敗的框架計數。當介面以全雙工模式運作時，此計數器不會進行累加。

這會在以下情形發生：

解決方式

基本疑難排解步驟列舉如下：

檢查裝置上的纜線連接。

在裝置上執行任何廠商特定硬體測試，以判斷裝置的硬體是否正常運作

提供監視的閾值。如此可將應用程式調整為較適合於您的環境。但請注意不要將閾值調得過高，以免漏掉重要事件。
