华为Radius认证、计费报文入门

敬业的IT人 互联网 佚名 2007-12-30 15:48:24
Radius报文中，code＝1是认证请求报文，code＝2和code＝3分别是认证通过和认证失败报文，这三种报文只在用户上线时产生。在用户上网的漫长过程中，是依靠code＝4报文来维系计费和用户在线信息。下文结合S3526和huawei-3com自带的radius属性简要介绍一下code＝4和与之相关的code＝5报文。 关于radius里面code＝4和code＝5的报文：code＝4：计费请求，由客户端发出（一般是配置了radius的交换机或5200）code＝5：计费回应。由radius服务器发出（cams发） 开始计费和结束计费是由code＝4里面的属性Acct-Status-Type(40)来决定的。1、Start          （计费开始）2、Stop           （计费结束）3、Interium-Update（计费更新）4、Reset-Charge 7、Accounting-On（3GPP中有定义，我们cams支持，设备现在不支持）8、Accounting-Off （3GPP中有定义，我们cams支持，设备现在不支持）9-14、Reserved for Tunnel Accounting15、Reserved for Failed其中Reset-Charge (Value=4)报文类型是针对华为扩展Radius 定义的。 我们主要看1、2、3三个属性，后面的属性暂时看不到。以下是在cams中一个完整的上线、计费、更新、下线信息的分析：   （10。153。29。200是S3526。中间的更新报文是从其他地方截取的，部分时间和流量参数不准确）% 2004-04-28 11:28:38 ;
