<p>宿舍以太网的连接由网线负责传输，如果网线，或者配线架，交换机这些物理设备本身的端口出现了问题，那么网络就当然无法连接🫠所谓对线，便是测试物理连接是否能工作的流程</p>

<p>打开寻线器，将寻线器的模式调到“对线”档位，将网线的一端插入到接口内，将另一端插入到要测试的端口</p>

<h3 class="anchor anchorWithStickyNavbar_LWe7" id="检查">检查<a href="#检查" class="hash-link" aria-label="Direct link to 检查" title="Direct link to 检查"></a></h3>
|
||
<p>如果寻线器上的1-8灯全部<strong>按顺序</strong>亮起的话，那么说明物理层连接没有问题，如果有哪个灯不亮，或是不按照顺序亮起的话，那么说明对应的电线不通;一般只要1,2,3,6灯亮起，那么网络就能保证最基本工作，但是网速会比较慢(大概100M)</p>

<p>对线只能说明寻线器到信号发射设备（楼层交换机，宿舍路由器等）的整体线路有没有问题，如果有问题，对线操作本身无法测出是哪一个部分有问题，这个时候，就需要我们进行系统的方法测试排查</p>

<p>下面是理想情况下校园网的结构，在实际工作中，每个片区我们只需要接触到其中的一部分：</p>
|
||
<!-- -->
|
||
<p>对线结果显示有问题的话，我们可以更换已知的正常设备来排查错误的地方</p>
|
||
<p>假如你遇到了这样的情况：用户ip查不到，怀疑是物理连接错误，于是你将用户的网线从ta的电脑上拔下来，插在对线器上：</p>
|
||
<!-- -->
|
||
<p>这个时候，对线还是失败的，于是你将用户的网线从端口上拔下来，拿出一根已知是工作正常的网线，插在对线器和端口上：</p>
|
||
<!-- -->
|
||
<p>这下成功对线了，由此我们可以得出<strong>是用户的网线有问题</strong></p>
|
||
<p>对于其它错误也是同样的道理，不断排除工作正常的环节，就可以确定工作不正常的环节，找到出现错误的地方之后，就可以按照情况进行修理了</p></div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="row margin-top--sm theme-doc-footer-edit-meta-row"><div class="col"><a href="https://github.com/ZSCNetSupportDept/website/tree/master/docs/wiki/03-技能/02-网络相关/对线.md" target="_blank" rel="noopener noreferrer" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_Z9Sw" aria-hidden="true"><g><path d="m34.5 11.7l-3 3.1-6.3-6.3 3.1-3q0.5-0.5 1.2-0.5t1.1 0.5l3.9 3.9q0.5 0.4 0.5 1.1t-0.5 1.2z m-29.5 17.1l18.4-18.5 6.3 6.3-18.4 18.4h-6.3v-6.2z"></path></g></svg>Edit this page</a></div><div class="col lastUpdated_JAkA"><span class="theme-last-updated">Last updated<!-- --> on <b><time datetime="2025-03-23T10:50:32.000Z" itemprop="dateModified">Mar 23, 2025</time></b></span></div></div></footer></article><nav class="pagination-nav docusaurus-mt-lg" aria-label="Docs pages"><a class="pagination-nav__link pagination-nav__link--prev" href="/docs/wiki/技能/电脑技能/设置路由器"><div class="pagination-nav__sublabel">Previous</div><div class="pagination-nav__label">设置路由器</div></a><a class="pagination-nav__link pagination-nav__link--next" href="/docs/wiki/技能/网络相关/寻线"><div class="pagination-nav__sublabel">Next</div><div class="pagination-nav__label">寻线</div></a></nav></div></div><div class="col col--3"><div class="tableOfContents_bqdL thin-scrollbar theme-doc-toc-desktop"><ul class="table-of-contents table-of-contents__left-border"><li><a href="#操作流程" class="table-of-contents__link toc-highlight">操作流程</a><ul><li><a href="#准备" class="table-of-contents__link toc-highlight">准备</a></li><li><a href="#检查" class="table-of-contents__link toc-highlight">检查</a></li></ul></li><li><a href="#排查" class="table-of-contents__link toc-highlight">排查</a><ul><li><a href="#流程" class="table-of-contents__link toc-highlight">流程</a></li></ul></li></ul></div></div></div></div></main></div></div></div><footer class="footer footer--dark"><div class="container container-fluid"><div class="footer__bottom text--center"><div class="footer__copyright">Copyright © 2025 ZSCNetworkSupport,Built with Docusaurus.</div></div></div></footer></div>
