基于三层以太网交换机的机房网络同传故障解析

Network Simultaneous Transmission Fault Analysis in Computer Room Based on Three-layer Ethernet Switch

随着网络安全逐渐被重视与网络硬件设备的升级需求,三层以太网交换机已经开始普遍被应用到网络接入端,作为网络安全的第一道屏障,因为在三层网络设备中以网络交换机中固化的操作系统为基础,利用程序策略控制自动的去执行各种限制条件从而提高了网络接入端的安全性。但由此带来的在机房中进行计算机网络数据同传时出现了数据链路连接不稳定和数据传输堵塞的问题也逐渐增多。文章通过对交换机内部程序与配置参数的研究和数据通信原理的分析,发现故障原因是数据转发模式造成的,并通过修改该模式的参数解决了数据同传的故障。

With the increasing emphasis on network security and upgrade requirements of network hardware,three-layer Ethernet switch has been widely applied to the network access terminal,as the first defense of the network security.Three-layer Ethernet switch is based on the solidified operating system in the network switch,using program strategy control automatically to perform various restrictions so as to improve the security of the network access terminal.But it also causes some problems.For example,there is unstable data link connection and data transmission congestion when conducting simultaneous network data transmission in the computer room.Through analyzing the internal procedure and switch configuration parameters and data communication principle,it is found that data forwarding mode is the cause of the malfunction.Therefore,by modifying parameters of the mode,the problem can be solved.
