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

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
