最佳答案
您好，请知：
Getting AC's IP Address Failed...
从反馈的提示来看，无法获取到IP地址。
以下是DHCP无法自动获取IP地址的参考思路及命令：
1、检查终端接入的端口是否已划分到了相应的VLAN中，且交换机是否能学习到终端的MAC地址：
dis vlan
dis mac-address int gi 1/0/1
2、检查VLAN IP和DHCP地址池分配的IP网段是否在同一个子网内：
dis cu int vlan
dis dhcp server ip-pool
3、检查DHCP内的IP地址是否足够使用：
dis dhcp server ip-in-use
4、如果是在远端的DHCP服务器上，检查路由是否可达：
dis ip routing-table
5、如果是在远端的DHCP服务器上，检查是否配置了DHCP中继：
dis cu int vlan
dis dhcp relay server-address

需要给AP降boot
一、
直接在AP（V7版本的WAP722S）上先将V5版本升级为V7版本。然后进行V7版本降级为V5。
二、
1、
把一个V5的AP接在V7的AC上：
大概10分钟左右，AP自动注册到AC上，AP变为V7版本
2、
由于v7 AP仅支持capwap协议，V5 AC降级V7 AP，需要将Capwap隧道协议打开：
[AC]_h 进入隐藏模式
[AC-hidecmd]fpl-diag enable 必须先enable
Are you sure you want to enable FPL-DIAG? [Y/N] y
% FPL-DIAG has been enabled.
[AC-hidecmd]fpl-diag drv_capwap_set 1 打开capwap
重启后，AP自动降级，过程如下：
%Jul 10 16:26:56:282 2019 ap1 CWC/6/CWC_IMG_DOWNLOAD_START: Started to download the image file wa4300s_fit.bin through the CAPWAP tunnel to AC 192.168.0.100. AC开启capwap隧道后，能够发现并下发对应的版本

此时发现AP无法上线，注意用V5 AC做完AP的降级操作后，一定要将Capwap协议关闭，另外不管是关闭还是开始Capwap都需要重启设备才会生效。
[H3C]_h 进入隐藏模式
[H3C-hidecmd]fpl-diag enable
Are you sure you want to enable FPL-DIAG? [Y/N] y
[H3C-hidecmd]fpl-diag drv_capwap_set 0
Set capwap flag to close success! 关闭capwap
查看AP已上线
AP版本为V5
