【摘要】 局域网中普遍存在端口环路问题,而交换机的端口环路检测功能无法有效解决该问题;为了找到交换机端口环路检测功能失效的原因;分析了端口环路检测工作原理以及在实际环境中的运行情况,并通过计算从产生环路到造成广播风暴的时间,得出端口环路检测功能缺陷的结论,最后提出解决方案。更多还原

【Abstract】 Port loop problems are prevalent in LAN,while the function of port loop detection of a switchboard can not effectively solve the problems.In order to find the cause for ineffectiveness of the function of port loop detection of the switchboard,this paper analyzes the working principles of port loop detection and its operation in actual circumstances and arrives at the conclusion of the existence of the defects of port loop detection by the calculation of the time from the loop to create broadcast storms,and finally puts forward the solution plan.更多还原
