RADIUS服务器进行MAC验证,配置nat，使无线接入端连接外网一、实验目的：通过Radius服务器的mac验证和路由器上的nat配置，使得在局域网内的无线设备可以上网。

二、实验拓扑图：三、使用的设备列表：S3610交换机3台AR28路由器1台AP无线路由器1台AC无线控制器1台Radius服务器1台四、具体的配置：步骤一：在AC上设置用户和做mac地址绑定，以及设计无线网<h3c>sys[h3c]sysname AC( 注意，AC为WA2620-AGN，本AC改名字的时候不能只打sys+名字，需要的是完整才能打出来sysname+名字) [AC]int vlan 1[AC-vlan-interfacel]undo ip add[AC-vlan-interfacel]vlan 2[AC-vlan2]vlan 4[AC-vlan4]int vlan 4[AC-vlan-interface4]ip add 192.168.4.1 24[AC-vlan-interface4]quit[AC]radius scheme yu[AC-radius-yu]server-type extended[AC-radius-yu]primary authentication 192.168.5.1[AC-radius-yu]primary accounting 192.168.5.1[AC-radius-yu]key authentication h3c(radius上默认的密钥为h3c，可以重设，所以在配置上需要一致，所以这里配置h3c)[AC-radius-yu]key accounting h3c[AC-radius-yu]user-name-format without-domain(注意：这条指令的意思是，不用域名，让你在radius添加账户时可以不带域名)[AC]radius scheme yu[AC-isp-yu]authentication lan-access radius-scheme yu[AC-isp-yu]authorization lan-access radius-scheme lu[AC-isp-yu]accounting lan-access radius-scheme lu[AC]int g1/0/1[AC-GigabitEthernet1/0/1]port link-type trunk[AC-GigabitEthernet1/0/1]port trunk permit vlan 1 to 2 4 [AC]interface WLAN-ESS7[AC-WLAN-ESS7] port access vlan 2[AC-WLAN-ESS7]port-security port-mode mac-authentication [AC]wlan service-template 7 clear[AC-wlan-st-7]ssid yu[AC-wlan-st-7]bind WLAN-ESS 7[AC-wlan-st-7] service-template enable[AC]wlan ap yu model wa2620-agn[AC-wlan-ap-yu]serial-id 219801A0A89112G03396[AC-wlan-ap-yu]radio 2[AC-wlan-ap-yu-radio-2]service-template 7[AC-wlan-ap-yu-radio-2]radio enable[AC]ip route-static 0.0.0.0 0.0.0.0 192.168.4.254[AC]local –user 90c1151c77db[AC-luser-90c1151c77db]password simple 90c1151c77db(这里是接入的无线客户端的mac地址)步骤二：在AC交换模块上配置连接<ac>oap connet slot 0<acsw>sys[acsw]int vlan 1[acsw-vlan-interfacel]undo ip add[acsw-vlan-interfacel]vlan 2[acsw-vlan2]vlan 4[acsw-vlan4]quit[acsw]interface GigabitEthernet1/0/8[acsw- GigabitEthernet1/0/8]port link-type trunk[acsw- GigabitEthernet1/0/8]port trunk permit vlan 1 to 2 4 [acsw]int g1/0/9[acsw- GigabitEthernet1/0/9] port link-type trunk[acsw- GigabitEthernet1/0/9] port trunk permit vlan 1 to 2 4 步骤三：配置Dhcp中继交换机上的ip地址池[dhcp]vlan 3[dhcp]dhcp enable[dhcp]dhcp server ip-pool 1[dhcp-pool-pool1]network 192.168.1.0 24[dhcp-pool-pool1]gateway-list 192.168.1.254[dhcp-pool-pool1]option 43 hex 80070000 01C0A804 01 [dhcp-pool-pool2]network 192.168.2.0 24[dhcp-pool-pool2]gateway-list 192.168.2.254[dhcp]int vlan 3[dhcp-vlan-interface3]ip add 192.168.3.1 24[dhcp]int e1/0/24[dhcp-Ethernet1/0/24] port access vlan 3[dhcp]rip 1[dhcp-rip-1]network 192.168.3.0[dhcp]dhcp server forbidden-ip 192.168.1.254[dhcp]dhcp server forbidden-ip 192.168.2.254步骤四：作为连接所有设备的交换机，配置其中继功能[sw]vlan 2[sw-vlan2]vlan 3[sw-vlan3]vlan 4[sw-vlan4]vlan 5[sw-vlan5]vlan 6[sw-vlan6]quit[sw] dhcp relay server-group 1 ip 192.168.3.1[sw]int vlan 1[sw-vlan-interfacel]ip add 192.168.1.254 24[sw-vlan-interfacel]dhcp select relay[sw-vlan-interfacel]dhcp relay server-select 1 [sw-vlan-interface2]ip address 192.168.2.254 24 [sw-vlan-interface2]dhcp select relay[sw-vlan-interface2]dhcp relay server-select 1 [sw-vlan-interface3]ip address 192.168.3.254 24 [sw-vlan-interface4]ip address 192.168.4.254 24 [sw-vlan-interface5]ip address 192.168.5.254 24 [sw-vlan-interface6] ip address 192.168.6.254 24 [sw]int e1/0/5[sw-Ethernet1/0/5]port access vlan 5[sw]int e1/0/6[sw- Ethernet1/0/6]port access vlan 2[sw]int e1/0/8[sw-Ethernet1/0/8]port link-type trunk[sw-Ethernet1/0/8]port trunk permit vlan 1 to 2 4 [sw]int e1/0/24[sw- Ethernet1/0/24]port access vlan 3[sw]rip 1[sw-rip-1]network 192.168.1.0[sw-rip-1]network 192.168.2.0[sw-rip-1] network 192.168.3.0[sw-rip-1] network 192.168.4.0[sw-rip-1] network 192.168.5.0[sw-rip-1] network 192.168.6.0[sw]dhcp enble[sw]ip route-static 0.0.0.0 0.0.0.0 192.168.6.1(这里指向下一跳的地址，即连接外网的路由器的接口地址)步骤五:配置路由器上的路由功能[RA]acl number 2000[RA-acl-basic-2000]rule 1 permit source 192.168.2.0 0.0.0.255[RA-acl-basic-2000]rule 2 permit source 192.168.6.0 0.0.0.255 [RA]rip[RA-rip]network 192.168.2.0[RA-rip] network 192.168.6.0[RA]int e0/0[RA- Ethernet0/0]ip add 192.168.6.1 24[RA]int e0/1[RA- Ethernet0/1]ip address 10.3.102.33 24[RA- Ethernet0/1]nat outbound 2000[RA]ip route-static 0.0.0.0 0.0.0.0 10.3.102.1至此，基本配置全部完成步骤五：测试配置结果查看3层注册是否成功假如3层注册不成功，我们应该一环环进行检查，ping测试AC ping switch测试DHCP ping switch测试3层注册成功后，我们检查下DHCP获取情况建立起RADIUS服务器手机连接过程与结果手机客户端连接后的DHCP获取情况查看一下路由器上nat转换的情况接下来看看我们连接的手机是不是可以正常的上网随便上的2个不同的网，再看看上面的各种图片证明，毫无疑问实验成功。
