篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了故障排查相关的知识，希望对你有一定的参考价值。

实验名称：故障排错实现全网互通

实验拓扑：技术分享图片

排错思路
1、先排查PC机

                        2、排查SW2

                        3、排查SW3

                        4、排查SW1

                        5、排查AR1

                        6、排查AR2

                        7、排查AR3

实验步骤：
