H3C-AC进行Portal认证.docx

一、 组网需求：
在BYOD组网方案下，我们主要通过iNode客户端、HTTP网页、终端Mac地址以及DHCP的Option属性这四种方式获取终端的操作系统和厂商信息，实现终端识别以便完成相应的权限策略控制。其中DHCP的Option属性方式可普遍用户各种场景。由于部署DHCP服务器并安装Agent插件的方式比较繁琐，这里我们以普通Portal认证为例介绍一种通过无线控制器的DHCP-snooping功能获取记录终端的option 55（终端操作系统）和option 60（终端厂商）信息并通过Radius属性上报给iMC服务器的典型配置。
WX系列AC、Fit AP、交换机、便携机（安装有无线网卡）、iMC服务器及其他智能终端。
二、 组网图：

三、 配置步骤：
1、 AC版本要求
WX系列AC从B109D012合入该特性，因此只有这个版本号及其以后的版本支持DHCP-snooping功能获取记录终端的option 55（终端操作系统）和option 60（终端厂商）信息并通过Radius属性上报给iMC服务器。WX系列AC可通过下面的命令查看内部版本号：

3、 iMC侧配置请参考KMS-21434《 WX系列AC与iMC配合实现无线Portal认证典型配置》，这里不再赘述。
4、 结果验证及抓包
1）AC上查看在线的客户端和portal在线用户信息：
<WX3024-AC>dis wlan client
 Total Number of Clients           : 2
                              Client Information
 SSID: option55
-------------------------------------------------------------------------------------------------

2477-0391-7720  -NA-        2/1      192.168.24.2            24
28e1-4cb5-8249  -NA-        2/1      192.168.24.3            24

 28e1-4cb5-8249   192.168.24.3      24     Vlan-interface24
 Total 2 user(s) matched, 2 listed.
2）iMC上通过终端设备管理查看终端的厂商、类型以及操作系统等信息：

3）查看AC的debugging信息，可以清楚看到Radius的code=[1]报文里携带了option 55和option 60的属性字段：

4）通过抓包我们也可以看到这个属性字段：

四、 配置关键点：
1、portal server的server-type必须选择imc，radius scheme的server-type必须选择extended。
2、全局视图下开启dhcp-snooping和dhcp-snooping binding record user-identity。
3、AC本身并不支持终端操作系统和厂商识别，只是把相关option 55和option 60信息传送给iMC完成终端识别。
