大中型WLAN网络简介

  • 本文介绍的WLAN网络是指利用频率为2.4GHz或5GHz的射频信号作为传输介质的无线局域网,相对于有线网络的铺设成本高,不便于网络调整和扩展、位置固定,移动性差等缺点,WLAN网络以其低廉的铺设成本、便捷的网络调整和扩展、灵活的可移动性获得了越来越广泛的应用。

组网需求

  • 图1,AC连接园区出口网关Router,并通过PoE交换机与AP连接,PoE交换机为AP供电。
  • 用户希望通过WLAN部署,提供名为“test”的无线网络方便用户随时随地接入。同时,用户希望通过路由器Router来做DHCP Server为用户提供10.10.10.0/24网段的IP地址,并在AC上对用户进行集中控制和管理。

配置思路

  • 1.配置AP、AC和上层网络设备之间实现网络互通。
  • 2.在AC上配置基于接口的DHCP服务器为AP分配IP地址,同时配置AC作为DHCP中继,由AC连接的路由器为STA分配IP地址。
  • 3.配置WLAN基本业务,保证用户能够通过WLAN网络接入Internet。

操作步骤

  • 1.在AC上配置NAC模式为统一模式(缺省值,不需配置)。配置SwitchA和AC,使AP与AC之间能够传输CAPWAP报文

  # 配置SwitchA连接AP的接口GE0/0/1加入VLAN100(管理VLAN),SwitchA连接AC的接口GE0/0/2加入VLAN100。

<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] vlan batch 100
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type trunk
[SwitchA-GigabitEthernet0/0/1] port trunk pvid vlan 100
[SwitchA-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2] port link-type trunk
[SwitchA-GigabitEthernet0/0/2] port trunk allow-pass vlan 100
[SwitchA-GigabitEthernet0/0/2] quit

   # 配置AC连接SwitchA的接口GE1/0/1加入VLAN100。

[HUAWEI] sysname AC
[AC] vlan batch 100
[AC] interface gigabitethernet 1/0/1
[AC-GigabitEthernet1/0/1] port link-type trunk
[AC-GigabitEthernet1/0/1] port trunk allow-pass vlan 100
[AC-GigabitEthernet1/0/1] quit
  •  2.配置AC与上层网络设备互通

  # 配置VLANIF101(业务VLAN)和VLANIF102。

[AC] vlan batch 101 102
[AC] interface vlanif 101
[AC-Vlanif101] ip address 10.10.10.1 24
[AC-Vlanif101] quit
[AC] interface vlanif 102
[AC-Vlanif102] ip address 10.11.10.2 24
[AC-Vlanif102] quit

   # 配置AC的缺省路由。

[AC] ip route-static 0.0.0.0 0.0.0.0 10.11.10.1  //配置缺省路由指向Router

   # 配置AC连接Router的接口GE1/0/2加入VLAN102。

[AC] interface gigabitethernet 1/0/2
[AC-GigabitEthernet1/0/2] port link-type trunk
[AC-GigabitEthernet1/0/2] port trunk allow-pass vlan 102
[AC-GigabitEthernet1/0/2] quit
  •  3.配置AC给AP分配IP地址,Router给STA分配IP地址。

  # 配置AC通过接口地址池为AP分配IP地址。

[AC] dhcp enable
[AC] interface vlanif 100
[AC-Vlanif100] ip address 192.168.10.1 24
[AC-Vlanif100] dhcp select interface  //配置基于接口的地址池
[AC-Vlanif100] quit

   # 配置AC作为DHCP中继并使能DHCP中继探测用户表项功能。

[AC] interface vlanif 101
[AC-Vlanif101] dhcp select relay  //配置DHCP中继功能
[AC-Vlanif101] dhcp relay server-ip 10.11.10.1  //配置DHCP中继所代理的DHCP服务器地址为Router上的IP地址10.11.10.1
[AC-Vlanif101] quit

   # 配置Router作为DHCP服务器为STA分配IP地址。

<Huawei> system-view
[Huawei] sysname Router
[Router] dhcp enable
[Router] ip pool sta  //配置地址池为STA分配IP地址
[Router-ip-pool-sta] gateway-list 10.10.10.1
[Router-ip-pool-sta] network 10.10.10.0 mask 24
[Router-ip-pool-sta] quit
[Router] vlan batch 102
[Router] interface vlanif 102
[Router-Vlanif102] ip address 10.11.10.1 24
[Router-Vlanif102] dhcp select global  //配置全局的地址池
[Router-Vlanif102] quit
[Router] interface gigabitethernet 2/0/0
[Router-GigabitEthernet2/0/0] port link-type trunk
[Router-GigabitEthernet2/0/0] port trunk allow-pass vlan 102
[Router-GigabitEthernet2/0/0] quit
[Router] ip route-static 10.10.10.0 24 10.11.10.2  //配置Router到达10.10.10.0/24网段的路由
  •  4.配置AC的系统参数

  # 配置AC的国家码。

[AC] wlan ac-global country-code cn
Warning: Modify the country code may delete configuration on those AP which use 
the global country code and reset them, continue?[Y/N]:y

   # 配置AC ID和运营商标识。

[AC] wlan ac-global ac id 1 carrier id other  //AC ID缺省为0,修改为1

   # 配置AC的源接口。

[AC] wlan
[AC-wlan-view] wlan ac source interface vlanif 100
  •  5.在AC上管理AP

  # 现场获取AP的MAC地址后,查看AP的设备类型ID。
