(Cisco Controller) >reset system both in 00:01:10 image swap reset-aps save-config
Time period is too short.推奨構成の午後12時02分01秒、再起動した後、bothそれが再起動2つのWLCを表します。（多分再起動後にAPが新しいイメージにアップグレードされましたが、それでもWLCまたは前の画像は、この時間は、WLCをリブートし、次のコマンドをノックします。）
(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.個人ブログ：https://cswk.work
