无线AP一直重启无法注册到控制器

liushanshan633 · ‎04-01-2019

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。

Rps-Cheers · ‎04-02-2019

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 · ‎04-08-2019

使用lwapp的话注意管理地址要和wlc在同一网段

请问现在这个bug有解决办法么？

yanyan · ‎03-06-2021

开过TAC回复：The radio is damaged, RMA is required.

Jiezhu1129 · ‎03-10-2021

MAC过滤下去就应该可以了但是不是在AAA的地方，遇到过好几次

sn270043685 · ‎03-23-2021

AP已经坏了，我们有很多这样的坏件，拿去RMA吧
