家里的无线系统是思科的wireless lan controoler 2504搭的，从14年之后就没动过。最近想用airplay，却发现wlc没做相关配置，想改发现密码已经忘记了。只好变身网管开始折腾
恢复密码
wlc在aireos 5.1以后的版本恢复密码还是容易的，只需要重启之后在console提示User的时候输入Restore-Password就行。找了个usb串口线，把它接到linux虚拟机里面用minicom一顿操作猛如虎，搞定。
注意：一定要是重启之后第一个提示User: 的时候输入Restore-Password

升级aireos
原来的wlc的版本是7.0，查了查，目前都8.5了，随手升个级吧。
看了看release note，8.5升级的建议是先升到8.3，再升级，我就先用8.3吧。cisco的升级包需要service account才能下。懒得再去找了，上4shared.com搜AIR-CT2500-K9-8-3 找到了AIR-CT2500-K9-8-3-102-0.aes，就是它了！下下来就开整
- 在linux虚拟机里面配好tftp server。把aes文件放到tftp的目录里面

3备注：由于需要备份配置文件，需要tftp server配置可写权限。
- in.tftpd启动参数加-c
- /var/lib/tftpboot 目录权限设成0777 这个有一定安全问题，弄完了之后去掉 - 登录wlc，备份配置
