二层网络注册配置举例

3  二层网络注册配置举例

3.1  组网需求

如图1所示，集中式转发架构下，AC旁挂在L2 switch1上，L3 switch做DHCP server为AP、Client和Host分配IP地址。需要实现无线客户端Client通过AP连接到AC上，并能与有线客户端Host互相访问，具体要求如下：

·     无线客户端Client通过VLAN 200接入网络，有线客户端Host通过VLAN 300接入网络；

·     AC属于VLAN 100，AC和AP之间通过二层网络建立连接。

·     L2 switch 1通过PoE方式给AP供电。

图1 Fit AP通过二层网络注册到AC配置举例组网图

3.2  配置思路

·     在L3 switch上开启DHCP server功能，AP、无线客户端Client和有线客户端Host都能通过DHCP server自动获取IP地址。

·     在L2 switch 1上开启PoE功能，为AP设备供电。

·     在AC上配置无线服务，确保Client可以通过配置的无线服务接入网络，并访问Host。

3.3  配置注意事项

·     配置AP的序列号时请确保该序列号与AP唯一对应。

·     配置L2 switch 1和AP相连的接口为Access口，禁止VLAN 1报文通过，以防止VLAN 1内报文过多。

3.4  配置步骤

3.4.1  配置L3 switch

1. 配置L3 switch的接口

# 创建VLAN 100，并配置IP地址，用于转发AC和AP间的CAPWAP隧道内的流量。
