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，此设置通常用于为出差和远程办公的用户以及小型办公室家庭办公室(SOHO)站点提供网络连接。

先决条件

使用的组件

本文档中的信息基于以下软件和硬件版本：

Cisco AS5400，带两个拨号功能卡(DFC)，提供216个NextPort调制解调器和8个T1卡。
Cisco IOS®软件版本12.3 mainline。
一个活动T1 PRI。
本地身份验证、授权和记帐(AAA)。如果您有AAA Radius或Tacacs+服务器，则可以使用该服务器为传入呼叫提供AAA。

此配置仅用于基本模拟和ISDN拨号。因此，AS5350和AS5400上支持的任何Cisco IOS软件版本都足够。要运行其他功能，请参阅软件顾问工具(仅注册客户)，以选择适合您需求的Cisco IOS版本和功能集。

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。

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)。您可以根据需要向此配置添加功能。

配置

本部分提供有关如何配置本文档所述功能的信息。

定义相关流量和空闲超时

NAS只处理来电，不进行出站呼叫，但我们仍定义相关流量。对于异步用户和ISDN用户，相关流量定义有不同的用途。

对于ISDN用户（与接口拨号器1对应）：

拨号程序接口上需要dialer-group和dialer-list命令，不管您是否想要强制执行空闲超时。拨号器接口上需要dialer-group 和dialer-list 命令，以避免封装失败。此要求仅适用于ISDN用户，而不适用于异步用户和组异步接口。

要实施空闲超时，请添加dialer in-band和dialer idle-timeout命令。如果配置了拨号器带内，但未配置拨号器空闲超时，则ISDN用户的空闲超时默认为两分钟。

如果希望您的ISDN用户在选择断开连接之前能够保持连接，请使用dialer idle-timeout 0。Cisco IOS软件版本12.1(3)T中引入了dialer idle-timeout的“零”选项。它设置无穷大超时。

对于异步用户（与接口组 — 异步0对应）：

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和dialer-group。还需要对应的拨号程序列表。dialer-group和dialer-list命令指定group-async-interface上的相关流量。

对于异步用户，相关流量仅用于重置空闲超时。如果未定义相关流量，则在拨号器空闲超时（默认为120秒）到期后，用户将断开连接，而不管他们是否在链路上传递流量。使用相关流量定义，NAS可识别这些数据包并重置空闲超时。这样，NAS仅在存在真正空闲的链路时断开用户连接。

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，如果用户浏览Web的时间不超过300秒(或对于指定的拨号器空闲超时)，则用户将断开连接。根据用户的流量模式配置相关流量。

如果希望您的异步用户在选择断开连接之前能够保持连接，请从group-async-interface删除以下命令：dialer in-band、dialer idle-timeout和dialer-group，如配置所示。您还可以借助dialer idle-timeout 0将空闲超时设置为无穷大。Cisco IOS软件版本12.1(3)T中引入了dialer idle-timeout 的“零”选项，该选项将超时设置为无穷大。

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 — 确保路由器与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配置的接口的常规诊断信息。如果拨号器正常启动，则必须显示“拨号器状态为数据链路层启动”消息。如果显示物理层为up，则表示线路协议已启用，但网络控制协议(NCP)未启用。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命令还显示计时器的配置以及连接超时之前的持续时间。
show caller user username detail — 显示特定用户的参数，如分配的IP地址、PPP和PPP捆绑参数等。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 dialer map。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。

以下是成功调用的一些show命令输出。请注意粗体部分和输出示例中提供的注释。将您获得的输出与此处显示的结果进行比较。

故障排除

本部分提供的信息可用于对配置进行故障排除。

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 — 显示有关拨号器接口上接收的数据包的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）的呼叫建立和断开。

注意：这相当于AS5200/AS5300上的debug modem csm。此调试在Cisco IOS软件版本12.0(4)XL中引入。
debug ppp negotiation — 显示链路控制协议(LCP)、身份验证和网络控制协议(NCP)协商期间PPP流量和交换的信息。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 身份验证协议消息，包括质询握手身份验证协议 (CHAP) 数据包交换和口令身份验证协议 (PAP) 交换。
debug ppp error - 显示与 PPP 连接协商和操作关联的协议错误和错误统计数据。
