目录


简介

在许多环境中,必需配置一个接入服务器从异步用户和ISDN用户上接收来电。这些用户可以无缝地连接到网络,就好象实际连接到网络一样。因此,此设置是常用的提供网络连通性为传播并且远程办公的用户,并且为小型办公室-家庭办公室(SOHO)站点。

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:

  • 有两个拨号特性卡的(DFCs) Cisco AS5400,提供216个NextPort调制解调器和8 T1卡德。

  • Cisco IOS�软件版本12.3主线。

  • 一激活T1PRI。

  • 本地认证、授权和核算(AAA)。如果有AAA RADIUS或TACACS+服务器,您能使用该服务器为呼入呼叫提供AAA。

此配置仅是为基本的模拟和ISDN拨入。所以,支持所有Cisco IOS软件版本AS5350和AS5400是满足的。要运行其它功能,参考软件建议工具(仅限注册用户)选择Cisco IOS版本和特性组适当为您的需要。

本文档中的信息都是基于特定实验室环境中的设备创建的。本文档中使用的所有设备最初均采用原始(默认)配置。如果您是在真实网络上操作,请确保您在使用任何命令前已经了解其潜在影响。

相关产品

该配置还可应用于 AS5350 或 AS5400 接入服务器。

注意: 可能也修改此配置与E1PRI端口一起使用

注意: 配置有Telco和其他物理特性的E1控制器供应的线性编码、帧。D信道配置(E1的接口串行x:15)和这里显示的类似。

此配置非常类似于拨号接入的一AS5200或AS5300配置。关于如何配置AS5200或AS5300的更多信息,请参阅配置有PRI的一接入服务器关于流入的异步呼叫和ISDN呼叫。两个之间的唯一的主要区别是dial-tdm-clock priority number t1_slot/port命令使用的分配在AS5350或AS5400的T1时钟优先级。

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

本文包括如何配置AS5350或AS5400系列接入服务器,以接受ISDN T1 PRI电路上的流入异步呼叫和ISDN呼叫。该配置只包括网络接入服务器接受呼叫所需的最小值(NAS)。您能添加功能到根据您的需要的此配置。

配置

!--- This is the same modem range configured with the group-range command 
!--- in interface Group-Async0.

 no flush-at-activation

!--- Prevents the router from flushing the first few packets on a connection.
!--- This command is used to prevent PPP timeout issues, and can be used to 
!--- avoid PPP startup issues.
!--- This is not required unless you encounter modem PPP call failures.

 autoselect during-login

!--- Displays the username:password prompt after modems connect (during exec login).
!--- This command is not neccessary if you use async mode dedicated under the 
!--- group-async interface. 

 autoselect ppp

!--- Automatically launches PPP if the router detects incoming PPP packets.

定义关注数据流和空闲超时

NAS只处理呼入呼叫和不做呼出,但是我们仍然定义了关注数据流。触发数据流定义有异步用户和ISDN用户的不同的目的。

对于ISDN用户(与Interface dialer 1)相应:

无论您是否要强制执行空闲超时,拨号程序接口中都需要 dialer-groupdialer-list 命令。必须在拨号程序接口中使用 dialer-groupdialer-list 命令以避免封装故障。此需求仅是为ISDN用户和不为异步用户和组异步接口。

要强制执行空闲超时,请添加频带内拨号拨号程序空闲Timeout命令。如果频带内拨号配置,但是拨号空闲超时不是,空闲超时默认为ISDN用户的两分钟。

如果您希望ISDN用户在选择断开之前一直保持连接状态,那么请使用dialer idle-timeout 0。“零"拨号空闲超时的选项在Cisco IOS软件版本12.1(3)T介绍。它设置无限超时。

对于异步用户(与Interface Group-Async 0相应) :

要为异步用户强制执行空闲超时,请在异步组接口中配置下列命令:dialer in-band, dialer idle-timeout,拨号组。还需要对应的拨号程序列表。dialer-groupdialer-list 命令指定异步组接口中的相关流量。

对于异步用户,相关流量仅用于重置空闲超时。如果关注数据流没有定义,用户将被断开,在拨号空闲超时(默认120秒)后到期,不管他们是否通过在链路的流量。使用触发数据流定义, NAS认可那些数据包并且重置空闲超时。只有当真有一个空闲链接时,这样, NAS断开用户。

您可以修改触发数据流,例如,只有HTTP (Web)数据流是触发数据流。在这种情况下,如果用户不浏览Web 300秒(或指定的拨号程序空闲超时)用户被断开。配置根据您的用户流量模式的关注数据流。

如果希望您的异步用户能坚持已连接,直到他们选择断开连接,请从group-async-interface删除这些命令:dialer in-band, dialer idle-timeout,拨号组如配置所显示。您能也设置空闲超时为无限在dialer idle-timeout 0帮助下。“零"拨号空闲超时的选项在Cisco IOS软件版本12.1(3)T介绍,并且设置无限超时。

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,验证第1层状态是否为活跃状态,是否第2层状态=MULTIPLE_FRAME_ESTABLISHED出现。此指令也显示活动的呼叫的数量。

  • show ppp multilink — 显示关于处于活动状态的多链路捆绑的信息。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,意味着线路通信协议出来,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命令在连接时间前也显示计时器的配置和持续时间。

  • show caller user username detail —表示一个特定用户的参数例如分配的IP地址, PPP和PPP捆绑参数,等等。如果您的Cisco IOS版本软件不支持此指令,请使用show users命令。

  • show dialer map —显示已配置的动态和静态拨号图。此指令可以被用于发现动态拨号映射是否被创建了。没有dialer map,您不能路由数据包。

这是成功的呼叫的一些show命令输出。支付对部分的注意在粗体字体和在输出示例提供的注释。比较您得到与显示的结果此处的输出。

故障排除

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。此信息有助于保证具有可以使用拨号程序接口的触发数据流。

  • 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。输出指示,当调制解调器线路更改状态。

  • debug csm modem —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。

    注意: 这与在AS5200/AS5300的debug modem csm是等同的。此调试在Cisco IOS软件版本12.0(4)XL介绍。

  • debug ppp协商—显示关于PPP流量的信息并且在链路控制协议(LCP)、验证和网络控制协议时交换(NCP)的协商。成功的PPP协商将首先开放LCP状态,然后进行验证,最后进行NCP协商。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,包括质询握手验证协议(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。
