一、配置AC1和AC2負載分擔方式的雙鏈路備份功能
在AC1上配置AC1作爲AP1的主用AC、AP2的備用AC，AC2作爲AP2的主用AC、AP1的備用AC
[AC1-wlan-view] ac protect enable
Warning: This operation maybe cause AP reset, continue?[Y/N]:y
[AC1-wlan-view] ap-system-profile name ap-system1
[AC1-wlan-ap-system-prof-ap-system1] primary-access ip-address 10.23.100.2
[AC1-wlan-ap-system-prof-ap-system1] backup-access ip-address 10.23.100.3
[AC1-wlan-ap-system-prof-ap-system1] quit
[AC1-wlan-view] ap-system-profile name ap-system2
[AC1-wlan-ap-system-prof-ap-system2] primary-access ip-address 10.23.100.3
[AC1-wlan-ap-system-prof-ap-system2] backup-access ip-address 10.23.100.2
[AC1-wlan-ap-system-prof-ap-system2] quit
[AC1-wlan-view] ap-group name ap-group1
[AC1-wlan-ap-group-ap-group1] ap-system-profile ap-system1
[AC1-wlan-ap-group-ap-group1] quit
[AC1-wlan-view] ap-group name ap-group2
[AC1-wlan-ap-group-ap-group2] ap-system-profile ap-system2
[AC1-wlan-ap-group-ap-group2] quit
二、配置AC1和AC2的雙鏈路備份功能
在AC1上，配置備份AC2的IP地址，AC1的優先級，用於雙鏈路備份
[AC1-wlan-view] ac protect enable
Warning: This operation maybe cause AP reset, continue?[Y/N]:y
[AC1-wlan-view] ac protect protect-ac 10.23.100.3 priority 0
在AC2上，配置主用AC1的IP地址，AC2的優先級，用於雙鏈路備份
[AC2-wlan-view] ac protect enable
Warning: This operation maybe cause AP reset, continue?[Y/N]:y
[AC2-wlan-view] ac protect protect-ac 10.23.100.2 priority 1
[AC2-wlan-view] quit
三、共同部分
在主用AC1上重啓AP，下發雙鏈路備份配置信息至AP
[AC1-wlan-view] ap-reset all
Warning: Reset AP(s), continue?[Y/N]:y
[AC1-wlan-view] quit
配置雙機熱備份功能 （不建議配置）
[AC1] hsb-service 0 #創建HSB主備份服務0並進入HSB備份服務視圖
[AC1-hsb-service-0] service-ip-port local-ip 10.23.102.1 peer-ip 10.23.102.2 local-data-port 10241 peer-data-port 10241 #建立HSB主備備份通道
[AC1-hsb-service-0] service-keep-alive detect retransmit 3 interval 1 #配置HSB主備服務報文的重傳次數和發送間隔
[AC1-hsb-service-0]quit
配置將WLAN業務與NAC業務綁定AC1的HSB主備服務
[AC1] hsb-service-type ap hsb-service 0 #配置WLAN業務綁定HSB主備服務
[AC1] hsb-service-type access-user hsb-service 0 #配置NAC業務綁定HSB主備服務
在AC2上創建HSB主備服務0，並配置其主備通道IP地址和端口號
[AC2] hsb-service 0
[AC2-hsb-service-0] service-ip-port local-ip 10.23.102.2 peer-ip 10.23.102.1 local-data-port 10241 peer-data-port 10241
[AC2-hsb-service-0] quit
配置將WLAN業務與NAC業務綁定AC2的HSB主備服務
[AC2] hsb-service-type ap hsb-service 0
[AC2] hsb-service-type access-user hsb-service 0
WEB配置界面
檢查配置命令
display hsb-service 0 #查看HSB主備服務的信息，看到Service State字段的顯示爲Connected，說明主備服務通道已經成功建立
display ac protect #查看雙鏈路備份開關狀態、AC的回切功能開關狀態、查看到雙鏈路備份的配置信息，WLAN視圖下AC的優先級和備AC的IP地址
display ap-system-profile { all | name profile-name }，查看AP系統模板視圖下AC的優先級和備AC的IP地址
