確認WLC HA 狀態正常

(Cisco Controller) >show redundancy summary
            Redundancy Mode = SSO ENABLED
                Local State = ACTIVE
                 Peer State = STANDBY HOT
                       Unit = Primary
                    Unit ID = 28:AC:9E:DF:93:D1
           Redundancy State = SSO
               Mobility MAC = 28:AC:9E:DF:93:D1
               Redundancy Port  = UP

Average Redundancy Peer Reachability Latency = 102 Micro Seconds
Average Management Gateway Reachability Latency = 863 Micro Seconds

重啟WLC

配置00:01:10之后重啟，時間太短報錯

(Cisco Controller) >reset system both in 00:01:10 image swap reset-aps save-config
Time period is too short.

推薦配置00:02:01之后重啟，both表示重啟2臺WLC。（有可能重啟之后AP已經升級到了新的鏡像，但是WLC依然還是以前的鏡像，這時候再敲一下下面的命令重啟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.
