局域网组建（无线网络如何配置）

WLAN的基本业务配置流程

案例：组建直连式二层无线局域网

配置以及参数数据

VLAN部署

在交换机以及AC上配置VLAN、Trunk。配置接入交换机S1的G0/0/1-3接口为Trunk接口，并且加入VLAN 100、VLAN 101。

G0/0/1、G0/0/2接口的默认VLAN为VLAN 100，当AP1、AP2加电启动后会加入VLAN 100，VLAN 100是AP的管理VLAN。G0/0/3接口的默认VLAN保持为默认值VLAN 1

[S1]vlan batch 100 101

[S1]interface gigabitethernet 0/0/1

[S1-GigabitEthernet0/0/1]port link-type trunk

[S1-GigabitEthernet0/0/1]port trunk pvid vlan 100

[S1-GigabitEthernet0/0/1]port trunk allow-pass vlan 100 101

[S1]interface gigabitethernet 0/0/2

[S1-GigabitEthernet0/0/2]port link-type trunk

[S1-GigabitEthernet0/0/2]port trunk pvid vlan 100

[S1-GigabitEthernet0/0/2]port trunk allow-pass vlan 100 101

[S1]interface gigabitethernet 0/0/3

[S1-GigabitEthernet0/0/3]port link-type trunk

[S1-GigabitEthernet0/0/3]port trunk allow-pass vlan 100 101

配置AC的接口G0/0/1加入VLAN 100和VLAN 101，接口G0/0/2加入VLAN 101。

[AC]vlan batch 100 101

[AC]interface gigabitethernet 0/0/1

[AC-GigabitEthernet0/0/1]port link-type trunk

[AC-GigabitEthernet0/0/1]port trunk allow-pass vlan 100 101

[AC-GigabitEthernet0/0/1]quit

[AC]interface gigabitethernet 0/0/2

[AC-GigabitEthernet0/0/2]port link-type trunk

[AC-GigabitEthernet0/0/2]port trunk allow-pass vlan 101

[AC-GigabitEthernet0/0/2]quit

IP地址部署

AC、R1上配置IP地址。在AC上配置VLANIF 100接口、VLANIF 101接口的IP地址。在R1上配置VLAN 101子接口G0/0/0.101的IP地址；创建LoopBack 10接口用于测试，该接口地址也模拟为DNS服务器的地址。

[AC]interface vlanif 100

[AC-Vlanif100]ip address 10.23.100.1 24

[AC]interface vlanif 101

[AC-Vlanif101]ip address 10.23.101.1 24

[R1]interface GigabitEthernet0/0/0.101

[R1-GigabitEthernet0/0/0.101]dot1q termination vid 101

[R1-GigabitEthernet0/0/0.101]ip address 10.23.101.2 255.255.255.0

[R1-GigabitEthernet0/0/0.101]arp broadcast enable

[R1]interface LoopBack 10

[R1-LoopBack10]ip address 10.10.10.10 24

VLAN间路由部署

VLAN间路由是由AC实现，AC、R1上配置合适的路由表，使得全网互通。

[AC]ip route-static 0.0.0.0 0.0.0.0 10.23.101.2

[R1]ip route-static 10.23.100.0 255.255.255.0 10.23.101.1

DHCP服务部署

在AC上部署DHCP，为AP和无线终端提供IP地址。在AC上配置VLANIF 100接口为AP提供IP地址，配置VLANIF 101接口为无线终端（STA）提供IP地址。

[AC]dhcp enable

[AC]interface vlanif 100

[AC-Vlanif100]dhcp select interface

[AC-Vlanif100]quit

[AC]interface vlanif 101

[AC-Vlanif101]dhcp select interface

[AC-Vlanif101]dhcp server excluded-ip-address 10.23.101.2

[AC-Vlanif101]dhcp server dns-list 10.10.10.10[AC-Vlanif101]quit

创建AP组

创建AP组，用于将相同配置的AP都加入同一AP组中。

[AC]wlan[AC-wlan-view]ap-group name ap-group1

创建域管理模板，在域管理模板下配置AC的国家码，并在AP组下引用域管理模板。

[AC-wlan-view]regulatory-domain-profile name default

[AC-wlan-regulate-domain-default]country-code cn （国家代码中国cn）

[AC-wlan-regulate-domain-default]quit

[AC-wlan-view]ap-group name ap-group1

[AC-wlan-ap-group-ap-group1]regulatory-domain-profile defaultWarning: Modifying the country code will clear channel, power and antenna gain configurations of the radio and reset the AP. Continue?[Y/N]:y

[AC-wlan-ap-group-ap-group1]quit

AP上线

配置AC的源接口。

[AC]capwap source interface vlanif 100

在AC上离线导入AP1、AP2，AP的ID分别为0和1，并将AP加入AP组“ap-group1”中。假设AP1的MAC地址为ac85-3d92-3340、AP2的MAC地址为ac85-3d92-1b60，并且根据AP的部署位置为AP配置名称，便于从名称上就能够了解AP的部署位置。例如，命名AP1为area_1、AP2为area_2。ap auth-mode用于配置AC对AP的认证模式，命令默认情况下为MAC认证，即通过MAC检查AP是否合法。

[AC]wlan

[AC-wlan-view]ap auth-mode mac-auth

[AC-wlan-view]ap-id 0 ap-mac ac85-3d92-3340

[AC-wlan-ap-0]ap-name area_1

[AC-wlan-ap-0]ap-group ap-group1Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configurations of the radio, Whether to continue? [Y/N]:y

[AC-wlan-ap-0]quit

将AP上电后，当执行命令查看到AP的“State”字段为“nor”时，表示AP正常上线。AP正常能上线是整个WLAN组网的关键一步，如果AP没有正常上线，请先仔细考虑有线网络的VLAN、Trunk、VLAN路由、DHCP代理、DHCP服务器是否正确？

[AC-wlan-view]display ap allInfo: This operation may take a few seconds. Please wait for a moment.done.Total AP information:nor : normal [2]------------------------------------------------------------------------ID MAC Name Group IP Type State STA Uptime---------------------------------------------------------------------------------------------0 00e0-fc4f-3de0 area_1 ap-group1 10.23.100.239 AP5030DN nor 1 1H:10M:48S1 00e0-fc3e-2040 area_2 ap-group1 10.23.100.6 AP5030DN nor 1 1H:10M:39S-------------------------Total: 2

配置WLAN业务参数

创建名为“wlan-net”的安全模板，并配置安全策略，这个安全策略就是STA连接WLAN时要使用的认证方式。例中配置的安全策略为WPA-WPA2+PSK+AES，密码为“a1234567”。

[AC-wlan-view]security-profile name wlan-net

[AC-wlan-sec-prof-wlan-net]security wpa-wpa2 psk pass-phrase a1234567 aes

[AC-wlan-sec-prof-wlan-net]quit

创建名为“wlan-net”的SSID模板，并配置SSID的名称为“wlan-net”，SSID就是STA扫描到的无线网络的名称。

[AC-wlan-view]ssid-profile name wlan-net

[AC-wlan-ssid-prof-wlan-net]ssid wlan-net

[AC-wlan-ssid-prof-wlan-net]quit

创建名为“wlan-net”的VAP模板，配置业务数据转发模式为直接转发、业务VLAN为VLAN 101，并且引用安全模板和SSID模板。

[AC-wlan-view]vap-profile name wlan-net

[AC-wlan-vap-prof-wlan-net]forward-mode direct-forward

[AC-wlan-vap-prof-wlan-net]service-vlan vlan-id 101
