RADIUS 服务器进行 MAC 验证

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

[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
