      某局点AP反复下载版本无法稳定在线

  首先, 我们先明确下故障现象,通过AP的输出信息我们能看到,AP可以正常的从AC上下载版本并启动,可以进入命令行,但是几秒钟之后就会再次重复下载版本。

  在AP命令行里我们能看到AP的版本和AC的版本不匹配,同时在AC的debug wlan capwap信息中,有如下的打印信息:

  *Jul 20 11:24:49:858 2020 vac CWS/7/FSM: Enter Image Download state.

??????  *Jul 20 11:24:49:858 2020 vac CWS/7/ERROR: Failed to get image file 0?000000rom the ram path?

??????  *Jul 20 11:24:49:858 2020 vac CWS/7/EVENT: Start get ap ipe offset in file /mnt/slot0#flash:/wa4300.ipe

  *Jul 20 11:24:49:858 2020 vac CWS/7/EVENT: Get the ap ipe offset in file /mnt/slot0#flash:/wa4300?ipe, errCode=0x0 offset=0 ipeSize=0

  AP的版本是从AC的flash中下载的,并不是从apimge中下载的。在版本说明书配套FIT AP列表中,有说明该类型的AP 的ipe文件不打包在AC中,需要单独将Ap的ipe文件导入AC根目录下。

  因此怀疑AC根目录下的AP版本上传错误,与AC版本号不匹配不一致,导致AP下载版本之后,又由于AC的版本校验机制,AC会将AP的软件版本与AC上保存的该AP型号的软硬件版本对应关系进行比较。如果软件版本一致,则允许CAPWAP隧道建立;如果软件版本不一致,则将此情况告知AP。AP收到版本不一致的消息后,会向AC请求版本并进行版本升级后,再重新与AC建立CAPWAP隧道连接。

  因此AP才会反复的下载版本,不能稳定在线。

  解决方法AC根目录下重新上传正确的Ap的ipe文件,AP稳定注册成功
