另⼀种⽅式是采⽤⽆线控制器AC加FIT AP（瘦AP）组⽹，采⽤这种⽅式FIT AP不需要配置，所有配置和版本都从AC上下载，⽅便管理和维护；这也说明了FIT AP离开了AC是不能⼯作的，⽽FAT AP是独⽴⼯作的，不需要AC的配合。

⽬前我们在北京运营商⽆线项⽬中采⽤的AP都是双模的，它们可以通过命令⾏切换成FAT AP或FIT AP模式。

由于当前客户订购的设备中没有⽆线控制器，AP仍以FAT AP⽅式开局。

h3c交换机典型故障归类和排除方法h3c交换机典型故障归类和排除方法一台交换机设备无论性能多么好，都会存在潜在的故障问题，就像人一样，无论多么健康，也总会出现有一些小毛病，能够做到防范于未然当然是好事，但是对于这个作为网络重臣的交换机来说，日夜“操劳”不断，偶尔出现问题也是在所难免的，所以当故障出现了，就要正视故障，及时地解决问题。

尽管交换机的故障多种多样，但是问题的根源就如:“天下武功出少林”一样，万变不离其宗，殊途同归，而且经常出现的也就这么几种，下面为大家归纳了几类典型的故障及其解决方法，读者也大可以触类旁通，举一反三，希望对交换机的日常故障处理工作有所帮助。

1.电源故障故障现象:开启交换机后，交换机没有正常运作，而且发现面板上的POWER指示灯并没有亮，而且风扇也不转动。

故障原因:这种故障通常是由于外部供电环境的不稳定，或者是电源线路老化，又或者是由于遭受雷击等而导致电源损坏或者风扇停止，从而导致交换机不能正常工作。

还有可能是由于电源缘故而导致交换机机内的其他部件坏的损坏。

解决方法:这类问题很容易发现也很容易解决，当发生这种故障时，首先检查电源系统，看看供电插座有没有电流，电压是否正常。

要是供电正常的话，那就要检查电源线是否有所损坏，有没有松动等，若电源线损坏的话就更换一条，松动了的话就重新插好。

如果问题还没有解决，那问题就应该落在交换机的电源或者是机内的其他部件损坏了。

预防方法也比较简单，首先要做的就是保证外部供电环境的稳定，这可以通过引入独立的电力线来提供独立的电源，并添加稳压器来避免瞬间高压或低压象。

可能的话，建议最好配置UPS系统(不间断电源)。

还有的就是采取必要的避雷措施，以防雷电对交换机造成的损害。

2.电路板故障故障现象:有一个电脑室经常出现一部分电脑不能访问服务器的现象。

一开始以为是网络布线不规范和网卡设置被学生修改了，所以机房管理员经常对网线进行测试和重新设置系统的网络配置。

H3C华三交换机基本配置命令大全，别到用的时候找不到了！本期我们一起来学习一下H3C最详细的基础命令。

一、不知道密码，如何恢复出厂设置1、开机启动，Ctrl+B进入bootrom菜单，选择恢复出厂设置。

2、用com线连上电脑，用超级终端进入，然后重启电脑，看提示按ctrl+b 进入bootrom模式，然后按照菜单提示删除flash中的.cfg文件，然后重启就可以了。

二、将Trunk端口添加到vlan中Trunk端口可以允许多个VLAN通过，也就是可以加入多个VLAN，所以Trunk 端口的VLAN加入不可能是一个一个地加，而是采取批量添加的方式进行。

但只能在以太网端口视图下进行配置，配置步骤如表7-11所示。

【示例1】使用port trunk permit vlan命令将中继端口Ethernet2/0/1加入到2、6、10、50～100 VLAN中。

1. <H3C> system-view2. System View: return to User View with Ctrl+Z.3. [H3C] interface Ethernet2/0/14. [H3C-Ethernet2/0/1] port trunk permit vlan 2 6 10 50 to 100【示例2】使用undo port trunk permit vlan命令将中继端口Ethernet2/0/1从VLAN 1中删除。

三、H3C交换机基础配置说明1、以太网端口的链路类型Access link：只能允许某一个vlan的untagged数据流通过。

Trunk link：允许多个vlan的tagged数据流和某一个vlan的untagged数据流通过。

Hybrid link：允许多个vlan的tagged数据流和多个vlan的untagged数据流通过。

hybrid link端口可以允许多个vlan的报文发送时不携带标签，而Trunk端口只允许缺省vlan的报文发送时不携带标签。

3、设备基本信息检查
检查设备的基本信息，如软件版本、补丁信息、系统时间等是否正确。

4、设备运行检查
检查设备的运行情况，如单板运行状态、设备复位情况、设备温度等是否正常。

5、端口内容检查
检查设备的端口信息，如端口协商模式、端口配置、端口状态等是否正确。

6、业务检查
检查设备运行的业务是否正常。

交换机操作手册1、通过交换机Console 口进行本地登录是登录交换机的最基本的方式，也是配置通过其他方式登录交换机的基础。

连接示意图如下：2、把电脑和交换机连接好后，交换机上电开机，然后在电脑上进行如下操作，首先点击开始－>程序－>附件－>通讯－>超级终端打开后出现下面图示，输入名称，可以任意输入。

输入完成点击确定，出现下面界面，连接时使用选择COM口，一般台式机为COM1或COM2，而笔记本经过转接，可能会产生COM3或COM4，也有可能是其他的，你可以在下面的选择项里看到，选择完成后点击确定。

通过上面的选择，现在到了对端口属性进行设置，一般情况下没有进行过修改，默认只要点击还原为默认值就可以了，然后再单击确定。

之后敲回车即可，会出现H3C>提示符，说明已经与交换机连接，可以进行配置了，如果没有可以重启交换机或检查连接是否正确。
