Cisco Wireless WLC 5520 HA config and show commands
现场2台Cisco wlc 5520 , need to establish HA
需要规划IP
备机那1台5520不需要配置业务SSID相关，只需要以下：
配置management IP,
指定Unit为Secondary
启用SSO
RP端口互联 （网线）
关于HA状态下的management IP，很多人有疑惑
为啥接口还有好几种，下面进行说明：
Management IP: 就是主控制器的管理Ip，用于AP注册的
Redundancy management IP: 当WLC发生切换后，原来的主控制器变成了备，那么这时它的Ip就使用redundancy management Ip
Peer Redundancy management IP: 备控制器的Ip
