简介

本文描述如何配置有虚拟模板和Dialer Profile接口的一接入服务器。

当流入的用户的连接需要一特定配置例如路由,超时, access-list时,混合的拨号配置文件和虚拟模板接口是有用的;Dialer Profile接口使用那。此Dialer Profile接口可以用于呼出呼叫。

其他流入的用户的连接,特定配置没有要求,使用虚拟模板接口。

注意: 这些需求可以用一每位用户配置也完成用验证、授权和统计(AAA)服务器。

先决条件

要求

本文档没有任何特定的要求。

使用的组件

使用Cisco IOSï ¿ Â在AS5300的½软件版本12.3(5)此配置开发并且测试了。然而,可以使用不同的硬件版本。例如,本文使用E1接口,但是可能也使用T1或BRI接口。

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始(默认)配置。如果您使用的是真实网络,请确保您已经了解所有命令的潜在影响。

规则

有关文档规则的详细信息,请参阅 Cisco 技术提示规则

背景信息

以下示例解释拨号配置文件或虚拟模板接口如何由呼入呼叫的接入服务器选择:

  1. 一个远程ISDN客户端在接入服务器拨号。它使用clientX作为用户名质询握手验证协议(CHAP)验证。

  2. 认证阶段发生,用户名(clientX),并且密码在D信道接口serial0:15接收。

  3. IOS软件证实是否能找到在Dialer Profile接口的dialer remote-name clientX命令:

    • 如果是,拨号程序远程名clientX配置的Dialer Profile接口然后用于绑定呼叫。

    • 如果没有,虚拟模板然后用于绑定呼叫。

有些一般信息可以在虚拟配置文件找到。

配置

本部分提供有关如何配置本文档所述功能的信息。

注意: 要查找本文档所用命令的其他信息,请使用命令查找工具仅限注册用户)。

网络图

此设置使用ISDN呼入呼叫。然而,这类配置可能也用于模拟呼入呼叫。名为“中央的”路由器也能呼叫client1和client2。

当拨号到路由器中央时:

  • client1使用Dialer Profile接口拨号1。

  • client2使用Dialer Profile接口dialer2。

  • client3使用虚拟模板1 (虚拟访问从虚拟模板复制)。

注意: 由于Cisco Bug ID CSCdu05390,配置至少两个dialer-pool接口是必须的。默认情况下路由器配置与单个Dialer Profile接口绑定所有呼入呼叫对该配置文件,并且虚拟模板为所有呼叫从未使用。

注意: 在发出 debug 命令之前,请参阅有关 Debug 命令的重要信息

以下调试打开:

  • debug isdn q931 —请显示关于呼叫建立及拆线的信息ISDN网络连接(在本地路由器(用户端)和网络之间的层3)。

  • debug dialer events —请显示关于在拨号接口接收的数据包的调试信息。

  • debug ppp协商—请显示在PPP启动期间传送的PPP数据包, PPP选项协商。

下面的输出显示从client1和client3的呼叫。
