ac主备

拓扑：

image-20230214141848098

规划：

本次采用两个vlan，

vlan10： 192.168.1.0/24

vlan20: 192.168.2.0/24

vlan10用于无线数据，给ap和无线终端下发vlan10的地址段，

vlan20 用于两个ac之间通信，也可以不做配置，统一使用vlan10

交换机配置：

思路：

连接ac端trunk放行vlan10，vlan20 连接ap端access，vlan10

接口部分：
<H3C>sys
[H3C] vlan 10
[H3C] vlan 20
[H3C-vlan10]int vlan 10
[H3C-Vlan-interface10]ip address  192.168.1.254 24
[H3C-Vlan-interface10]vlan 20
[H3C-vlan20]
[H3C-vlan20]int vlan 20
[H3C-Vlan-interface20]ip address  192.168.2.254 24
[H3C]int range g1/0/1 to g1/0/2
[H3C-if-range]port link-type trunk
[H3C-if-range]port trunk  permit  vlan  10 20
[H3C-if-range]int g1/0/3
[H3C-GigabitEthernet1/0/3]port access  vlan  10

dhcp部分：
[H3C]dhcp  enable
[H3C]dhcp  server  ip-pool 1
[H3C-dhcp-pool-1]network  192.168.1.0 24
[H3C-dhcp-pool-1]gateway-list 192.168.1.254

AC1配置

AC1与ac2配置基本一致，只需指定一下备用设备ip即可

#接口部分：

#无线部分：

[H3C-wlan-ap-ap1]wlan  tunnel-preempt enable #开启CAPWAP主隧道抢占功能。
[H3C-wlan-ap-ap1]backup-ac ip 192.168.2.252 #指向备用ac
[H3C-wlan-ap-ap1]radio 1
[H3C-wlan-ap-ap1-radio-1]service-template 1
[H3C-wlan-ap-ap1-radio-1]radio enable

#查看ap上线情况
[H3C]display  wlan  ap all

#在双链路备份组网环境中，当备份AC开启了CAPWAP主隧道抢占功能后，如果备份AC上配置的AP连接AC的优先级高于主AC上配置的优先级，则备份AC在延迟指定时间后将CAPWAP备份隧道切换为主隧道。
