clipping level

在Life Cycle Assurance概念中，经常出现clipping level，请专家给予指点！

我是直译：裁减水平（比如口令输入错误事件的裁减水平为3），意思就是将裁减水平以下（口令连续输错三次或三次以下）的日志视为一般性错误，以上（口令连续输错三次以上）的视为威胁性事件加以调查，目的在于将管理员的精力集中在重要问题（如有意攻击）的解决上，是一种管理手段。

For example, a clipping level of three can be set for reporting failed logon attempts at a workstation. Thus, three or fewer logon attempts by an individual at a workstation are not reported as a violation, thus eliminating the need for reviewing normal logon entry errors.

我觉得翻译成“限幅等级”或“限幅水平”会比较更贴切
