配置00:01:10之后重启，时间太短报错
(Cisco Controller) >reset system both in 00:01:10 image swap reset-aps save-config
Time period is too short.推荐配置00:02:01之后重启，both表示重启2台WLC。（有可能重启之后AP已经升级到了新的镜像，但是WLC依然还是以前的镜像，这时候再敲一下下面的命令重启WLC即可。）
(Cisco Controller) >reset system both in 00:02:01 image swap reset-aps save-config
System reset is scheduled for Nov 07 00:00:14 2019.
Current local time and date is Nov 06 23:58:13 2019.
Trap will not be generated as total delay is less than the trap time.
Active boot image will be changed before the reset.
Use ‘reset system cancel‘ to cancel the reset.
The system has unsaved changes.
Configuration will be saved before the system reset.个人博客：https://cswk.work
