如何重启Cisco LAP？

在Cisco WLC上进入对应的AP，能够看到Reset这个AP，但是这里会有两种选择：

看到上述的描述，可能很多人都不敢轻易的操作：

1、Hardware Reset：Perform a hardware reset on this AP

2、Set to Factory Defaults：Clear configuration on this AP and reset it to factory defaults

我们都知道LAP的配置是从WLC统一下发的。可能唯一觉得重要的，就是静态的IP地址，况且有时候我们使用的还是DHCP，并且使用了DHCP Option43，所以，即便是AP被Reset了，也可以获取IP地址和WLC的IP地址，然后重新加入到WLC。这一点是不用担心的。

从Set to Factory Defaults这里可以看到，有Clear All Config 和 Clear Config Except Static IP这两种选择。说明给静态配置IP的AP，也是留有选择的余地的。

那么如果只需要重启AP，选择Hardware Reset : Reset AP Now 就好了。如果是CLI命令行，输入如下命令：

(Cisco Controller) >config ap reset ?

<Cisco AP> Enter the name of the Cisco AP.

示例：

先查看一下目前AP是正常加入WLC的：

(Cisco Controller) >show ap summary

Number of APs.................................... 1

Global AP User Name.............................. Not Configured
Global AP Dot1x User Name........................ Not Configured

AP Name Slots AP Model Ethernet MAC Location Country IP Address Clients DSE Location
------------------ ----- -------------------- ----------------- ---------------- ---------- --------------- -------- --------------
AP3602I-01 2 AIR-CAP3602I-A-K9 30:f7:0d:xx:xx:xx  default location US 192.168.200.136 0 [0 ,0 ,0 ]

重启该AP：

(Cisco Controller) >config ap reset AP3602I-01

Would you like to reset AP3602I-01 ? (y/n)y

此时查看AP已经从WLC上消失：

(Cisco Controller) >show ap summary

Number of APs.................................... 0

Global AP User Name.............................. Not Configured
Global AP Dot1x User Name........................ Not Configured

稍等一会儿，再从WLC上查看，可以看到该AP已经重新加入WLC。

(Cisco Controller) >show ap summary

Number of APs.................................... 1

Global AP User Name.............................. Not Configured
Global AP Dot1x User Name........................ Not Configured

AP Name Slots AP Model Ethernet MAC Location Country IP Address Clients DSE Location
------------------ ----- -------------------- ----------------- ---------------- ---------- --------------- -------- --------------
AP3602I-01 2 AIR-CAP3602I-A-K9 30:f7:0d:xx:xx:xx  default location US 192.168.200.136 0 [0 ,0 ,0 ]

查看AP uptime和association time：

(Cisco Controller) >show ap uptime

Number of APs.................................... 1
Global AP User Name.............................. Not Configured
Global AP Dot1x User Name........................ Not Configured

AP Name Ethernet MAC AP Up Time Association Up Time
