无线AP一直重启无法注册到控制器

有部分AP一直重启,无法注册到控制器上。AP到控制器地址可达,在AP上指定了控制器的地址。控制器忽略了AP的证书。
哪位大佬可以分析一下,谢谢!

如果你用的是1500系列的AP,应该是遇到bug了,

如果方便的话,建议升级下AP或者WLC版本试试

1832i的,版本升级不了。因为无法设置AP的地址。如下:
#capwap ap ip 192.168.11.11 255.255.255.0 192.168.11.1
Capwap process not ready yet. Try after few moments.
CAPWAP socket is not ready, save static IP addr to config file.

等待一段时间后设备会自动重启,并报如下错误:

试了,无法进行升级。AP无法设置IP。

确认软件和硬件支持。可以尝试一下:
1、通过GUI来添加AP的MAC地址:Security>AAA>AP Policies

2、直接console到AP的CLI界面,然后输入capwap ap mode local

添加了,还是不行。有可能是bug。不过我现在的控制器命中了bug版本,还不能升级测试。

可以查看下此型号的wlc和此型号的ap的兼容性,有些不兼容的,是会出现这样的情况

瘦ap配置地址方法如下:
AP2F-3502-1# lwapp ap ip address 10.18.65.3 255.255.255.0
AP2F-3502-1# lwapp ap controller ip address 10.18.65.254
AP2F-3502-1# lwapp ap ip default-gateway 10.18.65.1

Wubin2010 发表于 2019-4-9 08:04:56

使用lwapp的话注意管理地址要和wlc在同一网段
