功能需求

WX系列AC结合iMC进行Portal认证实现终端识别的配置(Radius属性方式)

一、 组网需求:

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DHCPOption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DHCPOption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ACFit 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ACB109D012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ACiMC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

1AC上查看在线的客户端和portal在线用户信息:

 Total 2 user(s) matched, 2 listed.

2iMC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ACdebugging信息,可以清楚看到Radiuscode=[1]报文里携带了option 55option 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:

1portal serverserver-type必须选择imcradius schemeserver-type必须选择extended

2、全局视图下开启dhcp-snoopingdhcp-snooping binding record user-identity

3AC本身并不支持终端操作系统和厂商识别,只是把相关option 55option 60信息传送给iMC完成终端识别。
