Redundant System Information :

------------------------------

       Available system uptime = 4 hours, 18 minutes

Switchovers system experienced = 0

              Standby failures = 0

        Last switchover reason = none

                 Hardware Mode = Simplex

    Configured Redundancy Mode = sso

     Operating Redundancy Mode = Non-redundant

              Maintenance Mode = Disabled

                Communications = Down      Reason: Failure

Current Processor Information :

-------------------------------

               Active Location = slot 1

        Current Software state = ACTIVE

       Uptime in current state = 4 hours, 18 minutes

                 Image Version = Cisco IOS Software [Dublin], C9800-CL Software (C9800-CL-K9_IOSXE), Version 17.14.1, RELEASE SOFTWARE (fc1)

        Configuration register = 0x2102

               Recovery mode   = Not Applicable

             Fast Switchover   = Enabled

                Initial Garp   = Enabled

Peer (slot: 0) information is not available because it is in 'DISABLED' state

       my state = 13 -ACTIVE 

     peer state = 1  -DISABLED 

           Mode = Simplex

           Unit = Primary

        Unit ID = 1

Redundancy Mode (Operational) = Non-redundant

Redundancy Mode (Configured)  = sso

Redundancy State              = Non Redundant

     Maintenance Mode = Disabled

    Manual Swact = disabled (system is simplex (no peer unit))

 Communications = Down      Reason: Simplex mode

   client count = 128

 client_notification_TMR = 30000 milliseconds

           RF debug mask = 0x0   

Gateway Monitoring = Enabled 

Gateway monitoring interval  = 8 secs

（4.2）WLC2初始化配置

You will lose connectivity on applying the configuration. The device will reload and form a HA pair. Are you sure you want to proceed ?

在应用配置时将失去连通性。设备将重新加载并形成HA对。你确定要继续吗？

Device is reloading. Please login after sometime.

设备正在重新加载。请过一段时间再登录。

注意：是从角色重启，活动角色是不重启的。

（5）拓扑

Failover测试
如果您想通过强制故障转移来测试冗余，您可以拔下主 WLC（当前应该是活动 WLC），也可以使用以下命令：
redundancy force-switchover
