1.配置AC1为VRRP组1的Master,配置HSB(双机热备份功能),将AC1上的业务信息通过备份链路批量备份、实时备份到AC2上,保证在主设备故障时业务能够不中断地顺利切换到备份设备
1)在AC1上创建管理VRRP备份组,配置AC1在该备份组中的优先级为150
[AC1]interface Vlanif 100
[AC1-Vlanif100]vrrp vrid 1 virtual-ip 192.168.100.254
[AC1-Vlanif100]vrrp vrid 1 priority 150
[AC1-Vlanif100]quit
2)在AC1上创建HSB主备服务0,并配置其主备通道IP地址和端口号
[AC1-hsb-service-0]service-ip-port local-ip 192.168.100.1 peer-ip 192.168.100.2 local-data-port 10241 peer-data-port 10241
[AC1-hsb-service-0]quit
3)在AC1上创建HSB备份组0,并配置其绑定HSB主备服务0和管理VRRP备份组
[AC1]hsb-group 0
[AC1-hsb-group-0]bind-service 0
[AC1-hsb-group-0]track vrrp vrid 1 interface Vlanif 100
[AC1-hsb-group-0]quit
4)AC1配置NAC业务绑定HSB备份组、配置WLAN业务绑定HSB备份组、配置DHCP服务绑定HSB备份组
[AC1]hsb-service-type access-user hsb-group 0
[AC1]hsb-service-type ap hsb-group 0
[AC1]hsb-service-type dhcp hsb-group 0
5)使能双机热备功能
[AC1]hsb-group 0
[AC1-hsb-group-0]hsb enable
[AC1-hsb-group-0]quit
6)配置AC1的CAPWAP源地址,VRRP虚拟IP
[AC1]capwap source ip-address 192.168.100.254
2.AC2上配置VRRP方式的双机热备份,配置AC2为VRRP组的Backup设备,配置双机热备份功能(HSB),AC2接收AC1备份过来的业务信息,保证主设备故障时可以立即接管业务。
1)在AC2上配置VRRP备份组
[AC2]interface Vlanif 100
[AC2-Vlanif100]vrrp vrid 1 virtual-ip 192.168.100.254
[AC2-Vlanif100]quit
2) 在AC2上创建HSB主备服务0,并配置其主备通道IP地址和端口号
[AC2]hsb-service 0
[AC2-hsb-service-0]service-ip-port local-ip 192.168.100.2 peer-ip 192.168.100.1 local-data-port 10241 peer-data-port 10241
[AC2-hsb-service-0]quit
3)在AC2上创建HSB备份组0,并配置其绑定HSB主备服务0和管理VRRP备份组
[AC2]hsb-group 0
[AC2-hsb-group-0]bind-service 0
[AC2-hsb-group-0]track vrrp vrid 1 interface Vlanif 100
[AC2-hsb-group-0]quit
4)配置NAC业务绑定HSB备份组、配置WLAN业务绑定HSB备份组、配置DHCP服务绑定HSB备份组
[AC2]hsb-service-type access-user hsb-group 0
[AC2]hsb-service-type ap hsb-group 0
[AC2]hsb-service-type dhcp hsb-group 0
5)使能双机热备功能
[AC2]hsb-group 0
[AC2-hsb-group-0]hsb enable
[AC2-hsb-group-0]quit
6)配置AC2的CAPWAP源地址,VRRP虚拟IP
[AC2]capwap source ip-address 192.168.100.254
3.查看验证结果
1)AC1、AC2上查看VRRP状态,可以看到AC1的State字段显示为Master,AC2的State字段的显示为Backup
<AC1>display vrrp

2)AC1、AC2上执行display hsb-service 0命令,查看主备服务建立情况,service Status字段的显示为Connected,说明主备服务通道已经成功建立
<AC1>display hsb-service 0
Hot Standby Service Information:

4)AC1、AC2上检查AP1、AP2上线状态,AC1上AP的状态为nomal,而在AC2上AP的状态为Standby,AC2上的AP信息是由HSB备份组同步而来
<AC1>display ap all
