Wlan组网

组网需求：

• AC组网方式：旁挂三层组网。

• DHCP部署方式：

  • AC作为DHCP服务器为AP分配IP地址。

  • 汇聚交换机SwitchB作为DHCP服务器为STA分配IP地址。

• 业务数据转发方式：直接转发。

# 配置接入交换机SwitchA的GE0/0/1和GE0/0/2接口加入VLAN10、VLAN101和VLAN102，GE0/0/1的缺省VLAN为VLAN10。

# 配置汇聚交换机SwitchB的接口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，并创建接口VLANIF100，地址为10.23.100.2/24。

配置DHCP服务为AP和STA分配IP地址
# 在SwitchB上配置DHCP中继，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上创建VLANIF101和VLANIF102接口为STA提供地址，并指定默认网关。
DNS服务器地址请根据实际需要配置。常用配置方法如下：

    接口地址池场景，需要在VLANIF接口视图下执行命令dhcp server dns-list ip-address &<1-8>。
    全局地址池场景，需要在IP地址池视图下执行命令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
