WLC HA模式下的注意事項

管理控制器:
1、控制器預設開啟的是SSH (CLI),Secure Web/https (GUI)
2、登入控制器的管理地址為Active裝置所控制(主備的配置同步,所以管理地址一致)
3、WLC HA狀態下,不能console到standby WLC
4、可以嘗試使用Standby WLC的RMI介面登入到Standby WLC(如下第1、2點,備份WLC使用RMI完成一切外部交流及管理賬戶認證)

Standby控制器:
1、The standby WLC uses the redundancy management interface for any external communications such as when talking to Syslog, NTP server, TFTP server, and so on.
Standby控制器使用RMI介面來完成一切外部交流(如與Syslog、NTP、TFTP Server)

2、On the standby WLC, the management user authentication and accounting is performed on the redundancy management interface,
RADIUS or TACACS+ server can be used for user authentication, apart from a local management user account. To support this, the redundancy interface IP address(es) should be added as network device on the RADIUS or TACACS+ server.
The authentication request is sent to RADIUS or TACACS+ server over redundancy management interface. Whenever you log on to the standby WLC, accounting message is sent to the RADIUS server. The purpose of the accounting message is to log the admin logon events on the standby WLC console.
在Standby WLC上,在冗餘管理介面RMI上執行管理使用者認證和審計

3、在Active控制器檢視Standby 控制器狀態:(Standby WLC的所有執行緒的CPU和記憶體統計資訊每10秒與Active WLC同步)
show redundancy summary
show redundancy peer-system statistics
show redundancy peer-process cpu
show redundancy peer-process memory
