项目须知:了解capwap隧道，AC主备之间切换流程
配置步骤
1、交换机SW配置：vlan IP地址 DHCP
#配置vlan 、IP地址
[SW]vlan 100
[SW]int range g1/0/1 to g1/0/3
[SW-if-range]port access vlan 100
[SW-Vlan-interface100] ip address 100.1.1.1 255.255.255.0
#配置DHCP服务器，给AP 分配IP ，本实验中用SW模拟DHCP服务器
[SW]dhcp enable
[SW]dhcp server ip-pool ap
[SW-dhcp-pool-ap] network 100.1.1.0 23
[SW-dhcp-pool-ap] gateway-list 100.1.1.1
[SW]dis dhcp server ip-in-use //查看AP获取地址情况
IP address Client identifier/ Lease expiration Type
Hardware address
100.1.1.2 0035-6330-642e-6234 Dec 17 09:14:26 2023 Auto(C)
2、无线控制器AC-2(主AC)配置
[AC2-Vlan-interface1] ip address 100.1.1.2 24
[AC2]wlan ap ap1 model WA6320-HCL //手动注册
[AC2-wlan-ap-ap1]serial-id H3C_5C-0E-38-5B-04-00
[AC2-wlan-ap-ap1] priority 7 //优先级7最高，代表主
[AC2-wlan-ap-ap1]echo-interval 5 //AP和AC之间通过保活机制来检查控制隧道是否正常工作默认10S
[AC2-wlan-ap-ap1]echo-count 3 //连续3次，没有回应，则AP状态从R-I初始化状态
3、无线控制AC-3（备）配置
[AC3-Vlan-interface1] ip address 100.1.1.10 24
[AC3]wlan ap ap1 model WA6320-HCL //手动注册
[AC3-wlan-ap-ap1]serial-id H3C_5C-0E-38-5B-04-00
[AC3-wlan-ap-ap1] priority 7 //优先级7最高，代表主
[AC3-wlan-ap-ap1]echo-interval 5 //AP和AC之间通过保活机制来检查控制隧道是否正常工作默认10S
[AC3-wlan-ap-ap1]echo-count 3 //连续3次，没有回应，则AP状态从R-I初始化状态
4、测试
#
[AC2]dis wlan ap all //正常情况，AP会注册到主AP上
AP name APID State Model Serial ID
ap1 1 R/M WA6320-HCL H3C_5C-0E-38-5B-04-00
#
[AC2]int vlan 1
[AC2-Vlan-interface1]shutdown //关闭AC互联接口，
#
在AC3上收到AP与AC3之间的capwap隧道建立完成消息
%Dec 16 11:08:53:003 2023 AC-3 CWS/6/CWS_AP_UP: -MDC=1; Master CAPWAP tunnel to AP ap1 went up//
[AC3]dis wlan ap all //AC3中AP状态从I-R，切换
AP name APID State Model Serial ID
ap1 1 R/M WA6320-HCL H3C_5C-0E-38-5B-04-00
