目录


简介

在许多环境,您需要配置能接受从异步和ISDN用户的呼入呼叫的接入服务器。这些用户然后能无缝地连接到网络,好象他们物理的存在。这样设置是常用的提供网络连通性给传播并且是远程办公者的用户,并且为小型办公室-家庭办公室(SOHO)站点。

本文描述如何配置接入服务器接受流入的异步呼叫和ISDN呼叫在ISDN T1PRI电路。配置为网络接入服务器(NAS)提供要求的最低设置接受呼叫。您能添加其它功能到根据您的需要的此配置。

先决条件

要求

本文档没有任何特定的要求。

使用的组件

本文档中的信息基于以下软件和硬件版本:

  • 运行Cisco IOS�软件版本12.2(5)的Cisco AS5300用192个MICA调制解调器和八个T1端口。

  • 两个T1 PRI。

  • 运行Microsoft Windows.的PC此PC有一个模拟调制解调器和一个电话连接对公共交换机电话网。连接对AS5300的PC拨号T1PRI。

  • Cisco 800及1600系列路由器用ISDN BRI电路。这些路由器是ISDN拨入客户端。提供Cisco1600的配置。您能适用于此客户端配置有BRI接口的所有路由器。

  • 本地认证、授权和核算(AAA)。如果有AAA RADIUS或TACACS+服务器,您能使用之一他们为呼入呼叫提供AAA。

注意: Cisco 800路由器的配置类似于Cisco 1600路由器的配置和没有包括在本文。

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。

相关产品

您能以例如有T1或PRI卡和内部数字调制解调器的所有路由器使用此配置(MICA、NextPort或者Microcom)。有T1的所有AS5xxx系列路由器或PRI卡和数字调制解调器在此配置方面能使用概念。

Cisco 2600系列路由器不支持内部数字调制解调器。假设路由器有T1或PRI WIC或网络模块,您能配置Cisco 2600系列路由器接受仅ISDN呼叫。

Cisco 3600系列路由器可以支持ISDN和调制解调器呼叫。然而, Cisco 3600系列路由器要求T1或PRI WIC或网络模块和NM-xDM数字调制解调器网络模块。

您能也做修改以E1或PRI端口使用此配置。配置有您的Telco供应的linecoding,成帧和其他物理特性的E1控制器。D信道配置(E1s的接口序列x:15)类似于在本文显示的那个。

验证

本部分所提供的信息可用于确认您的配置是否正常工作。

命令输出解释程序工具仅限注册用户)支持某些 show 命令,使用此工具可以查看对 show 命令输出的分析。

  • show isdn status —保证路由器用ISDN交换机正确通信。在输出中,请保证第1层状态活跃的,并且第2层状态=MULTIPLE_FRAME_ESTABLISHED出现。出现。此指令也显示活动的呼叫的数量。有关详细信息,请参阅使用 show isdn status 用于 BRI 故障排除

  • show ppp multilink —显示关于活动多链路捆绑的信息。使用此指令验证多链路连接。

  • show dialer [interface type number] —显示为DDR配置的接口的一般诊断信息。如果拨号程序适当地过来, Dialer state is data link layer up消息必须出现。如果physical layer up出现,暗示是线路通信协议出来,但是网络控制协议(NCP)没有。启动拨号的数据包的源地址和目标地址显示在 dial reason line 中。此show命令也显示计时器的配置和连接超时前的时间。

  • show caller user username detail —表示特定用户,例如,分配的IP地址的参数, PPP和PPP捆绑参数。如果您的Cisco IOS软件的版本不支持此命令,请使用show user命令

  • show dialer map —显示已配置的动态和静态拨号图。您能使用此命令证实动态拨号映射是否创建。如果没有 Dialer Map,则无法路由数据包。

故障排除命令

命令输出解释程序工具仅限注册用户)支持某些 show 命令,使用此工具可以查看对 show 命令输出的分析。

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

  • debug dialer —显示关于在拨号接口接收的数据包的DDR调试信息。此信息可帮助保证那里是使用拨号接口的关注数据流。

  • debug isdn q931 -显示ISDN网络连接(第3层)呼叫建立和卸载。

  • debug modem —显示在接入服务器的调制解调器线路活动。输出显示,当调制解调器线路更改状态。

  • debug modem csm —使您排除故障在路由器的呼叫交换模块(CSM)问题用内部数字调制解调器。使用该指令,您能跟踪呼入和呼出的呼叫交换排序的完成情况。

  • debug ppp协商—显示关于PPP流量和交换的信息,并且协商链路控制协议(LCP)、验证和网络控制协议(NCP)。一个成功的PPP协商协议首先开启LCP状态,然后是鉴权,最后协商NCP。在 LCP 协商期间建立多链路参数,如最大接收重建单元 (MRRU)。

  • debug ppp authentication —显示PPP认证协议消息,包括CHAP信息包交换和密码认证协议交换。

  • debug ppp error -显示与PPP连接协商和操作相关的协议错误和错误统计数据。
