華為無線網絡射頻調優及WLAN跨VLAN的三層漫游示例

1.業務需求

企業用戶通過WLAN接入網絡，以滿足移動辦公的最基本需求。
在覆蓋區域內移動發生跨VLAN的漫游時，不影響用戶的業務使用。

2.組網需求

AC組網方式：旁掛三層組網。
DHCP部署方式：
- AC作為DHCP服務器為AP分配IP地址。
- 匯聚交換機SwitchB作為DHCP服務器為STA分配IP地址。
業務數據轉發方式：直接轉發。
拓撲圖如下圖

3.數據規劃

AC數據表規劃如下：

4.配置思路

1）配置AP、AC和周邊網絡設備之間實現網絡互通。

2）配置AP上線。

創建AP組，用于將需要進行相同配置的AP都加入到AP組，實現統一配置。
配置AC的系統參數，包括國家碼、AC與AP之間通信的源接口。
配置AP上線的認證方式并離線導入AP，實現AP正常上線。

3）配置WLAN業務參數，實現STA訪問WLAN網絡功能。

說明：

當用戶新開局時，對于AP的射頻信道的設置，用戶可根據網絡規劃手動指定，也可使用射頻調優功能自動選擇最佳信道。

本例中采用射頻調優功能自動選擇最佳信道。

5.操作步驟

5.1配置周邊設備

接口GE0/0/1加入VLAN10、VLAN101和VLAN102
接口GE0/0/2加入VLAN100
接口GE0/0/3加入VLAN101和VLAN102，
創建接口VLANIF100，地址為10.23.100.2/24。

<HUAWEI> system-view
[HUAWEI] sysname SwitchB
[SwitchB] vlan batch 10 100 101 102
[SwitchB] interface gigabitethernet 0/0/1
[SwitchB-GigabitEthernet0/0/1] port link-type trunk
[SwitchB-GigabitEthernet0/0/1] port trunk allow-pass vlan 10 101 102
[SwitchB-GigabitEthernet0/0/1] quit
[SwitchB] interface gigabitethernet 0/0/2
[SwitchB-GigabitEthernet0/0/2] port link-type trunk
[SwitchB-GigabitEthernet0/0/2] port trunk allow-pass vlan 100

[SwitchB] interface gigabitethernet 0/0/3
[SwitchB-GigabitEthernet0/0/3] port link-type trunk
[SwitchB-GigabitEthernet0/0/3] port trunk allow-pass vlan 101 102
[SwitchB-GigabitEthernet0/0/3] quit
[SwitchB] interface vlanif 100
[SwitchB-Vlanif100] ip address 10.23.100.2 24
[SwitchB-Vlanif100] quit

配置Router的接口：

接口GE1/0/0加入VLAN101和VLAN102
創建接口VLANIF101并配置IP地址為10.23.101.2/24
創建接口VLANIF102并配置IP地址為10.23.102.2/24。

<Huawei> system-view
[Huawei] sysname Router
[Router] vlan batch 101 102
[Router] interface gigabitethernet 1/0/0
[Router-GigabitEthernet1/0/0] port link-type trunk
[Router-GigabitEthernet1/0/0] port trunk allow-pass vlan 101 102
[Router-GigabitEthernet1/0/0] quit
[Router] interface vlanif 101
[Router-Vlanif101] ip address 10.23.101.2 24
[Router-Vlanif101] quit
[Router] interface vlanif 102
[Router-Vlanif102] ip address 10.23.102.2 24
[Router-Vlanif102] quit

5.2配置AC與其它網絡設備互通

配置AC的接口GE0/0/1加入VLAN100，并創建接口VLANIF100。

<AC6605> system-view
[AC6605] sysname AC
[AC] vlan 100
[AC-vlan100] quit
[AC] interface vlanif 100
[AC-Vlanif100] ip address 10.23.100.1 24
[AC-Vlanif100] quit
[AC] interface gigabitethernet 0/0/1
[AC-GigabitEthernet0/0/1] port link-type trunk
[AC-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
[AC-GigabitEthernet0/0/1] quit

配置AC到AP的路由，下一跳為SwitchB的VLANIF100。

[AC] ip route-static 10.23.10.0 24 10.23.100.2

5.3配置DHCP服務為AP和STA分配IP地址

在SwitchB上配置DHCP中繼，代理AC分配IP地址

[SwitchB] dhcp enable
[SwitchB] interface vlanif 10
[SwitchB-Vlanif10] ip address 10.23.10.1 24
[SwitchB-Vlanif10] dhcp select relay
[SwitchB-Vlanif10] dhcp relay server-ip 10.23.100.1
[SwitchB-Vlanif10] quit

在SwitchB上創建VLANIF101和VLANIF102接口為STA提供地址，并指定默認網關

說明：

DNS服務器地址請根據實際需要配置。常用配置方法如下：

接口地址池場景，需要在VLANIF接口視圖下執行命令dhcp server dns-list ip-address &<1-8>。

全局地址池場景，需要在IP地址池視圖下執行命令dns-list ip-address &<1-8>。

[SwitchB] interface vlanif 101
[SwitchB-Vlanif101] ip address 10.23.101.1 24
[SwitchB-Vlanif101] dhcp select interface
[SwitchB-Vlanif101] dhcp server gateway-list 10.23.101.2
[SwitchB-Vlanif101] quit
[SwitchB] interface vlanif 102
[SwitchB-Vlanif102] ip address 10.23.102.1 24
[SwitchB-Vlanif102] dhcp select interface
[SwitchB-Vlanif102] dhcp server gateway-list 10.23.102.2
[SwitchB-Vlanif102] quit

在AC上創建全局地址池為AP提供地址

[AC] dhcp enable
[AC] ip pool huawei
[AC-ip-pool-huawei] network 10.23.10.0 mask 24
[AC-ip-pool-huawei] gateway-list 10.23.10.1
[AC-ip-pool-huawei] option 43 sub-option 3 ascii 10.23.100.1
[AC-ip-pool-huawei] quit
[AC] interface vlanif 100
[AC-Vlanif100] dhcp select global
[AC-Vlanif100] quit

5.4配置AP上線

創建AP組

用于將相同配置的AP都加入同一AP組中。

[AC] wlan
[AC-wlan-view] ap-group name ap-group1
[AC-wlan-ap-group-ap-group1] quit
[AC-wlan-view] ap-group name ap-group2
[AC-wlan-ap-group-ap-group2] quit

創建域管理模板

在域管理模板下配置AC的國家碼并在AP組下引用域管理模板。

[AC-wlan-view] regulatory-domain-profile name default
[AC-wlan-regulate-domain-default] country-code cn
[AC-wlan-regulate-domain-default] quit

[AC-wlan-view] ap-group name ap-group1
[AC-wlan-ap-group-ap-group1] regulatory-domain-profile default
Warning: Modifying the country code will clear channel, power and antenna gain configurations of the radio and reset the AP. Continu
e?[Y/N]:y 
[AC-wlan-ap-group-ap-group1] quit

[AC-wlan-view] ap-group name ap-group2
[AC-wlan-ap-group-ap-group2] regulatory-domain-profile default
Warning: Modifying the country code will clear channel, power and antenna gain configurations of the radio and reset the AP. Continu
e?[Y/N]:y 
[AC-wlan-ap-group-ap-group2] quit
[AC-wlan-view] quit

配置AC的源接口

[AC] capwap source interface vlanif 100

注冊AP

在AC上離線導入AP，并將area_1和area_2分別加入AP組ap-group1和ap-group2中。

假設AP的MAC地址為60de-4476-e360，并且根據AP的部署位置為AP配置名稱，便于從名稱上就能夠了解AP的部署位置。例如MAC地址為60de-4476-e360的AP部署在1號區域，命名此AP為area_1。

[AC-wlan-view] ap-id 0 ap-mac 60de-4476-e360
[AC-wlan-ap-0] ap-name area_1
Warning: This operation may cause AP reset. Continue? [Y/N]:y 
[AC-wlan-ap-0] ap-group ap-group1
Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configuration
s of the radio, Whether to continue? [Y/N]:y 
[AC-wlan-ap-0] quit
[AC-wlan-view] ap-id 1 ap-mac dcd2-fc04-b500
[AC-wlan-ap-1] ap-name area_2
Warning: This operation may cause AP reset. Continue? [Y/N]:y 
[AC-wlan-ap-1] ap-group ap-group2
Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configuration
s of the radio, Whether to continue? [Y/N]:y 
[AC-wlan-ap-1] quit

注：

AP上電后，當執行命令display ap all查看到AP的State字段為nor時，表示AP正常上線。

5.5配置WLAN業務參數

創建名為wlan-net的安全模板，并配置安全策略。

[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
