目录


简介

在本文的配置示例说明如何配置的数字号码识别服务(DNIS)支持主速率接口和如何设置调制解调器汇集。提供三配置:

  1. 调制解调器汇集用在定义的多个调制解调器pool-range。

  2. 调制解调器汇集用在的一个调制解调器pool-range。

  3. 没有a的调制解调器汇集pool-range。

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。

  • Cisco IOSï ¿  ½软件版本11.3(1.1)T或以上。

  • PRI由DNIS支持的Telco设置了。

  • Cisco AS5x00系列路由器。

注意: 调制解调器汇集不是可能的在Cisco 3600系列路由器。

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。

规则

有关文档规则的详细信息,请参阅 Cisco 技术提示规则

背景理论

如果使用远程拨入用户服务(RADIUS)作为您的认证协议,您需要认识RADIUS (IETF)记帐属性30 (主机ID)。

主机ID允许网络接入服务器(NAS)发送编号用户呼叫作为访问请求信息包一部分(使用DNIS或相似的技术)。主机ID,当与PRI一起使用时, ISDN和调制解调器呼叫仅支持在Cisco AS5x00。

配置

本文档使用如下所示的配置。

  • 在pool-range a的多个调制解调器

  • 在池的一个调制解调器

  • 没有a的调制解调器汇集pool-range

本部分提供有关如何配置本文档所述功能的信息。

注意: 要寻找关于用于本文的指令的其他信息,请使用命令查找工具

网络图

本文档使用下图所示的网络设置。

配置1 :在pool-range a的多个调制解调器

配置注释

客户拨号5557528并且连接到在的一个调制解调器pool-range 3条到5.线路3到5配置对autocommand telnet一个特定IP地址的用户,在登录用户ID和密码输入在路由器提示后(>)。

警告 警告: 当您在最大连接数时配置被叫号码功能,并且不放置, Cisco路由器默认为调制解调器编号在池的。在此配置示例中,调制解调器3到5配置,因此Cisco IOS软件在max-conn 3放置在called-number命令结束时

如果更换调制解调器编号在池的,您必须手工更换最大连接数

此配置示例使用本地认证。

配置3 :没有a的调制解调器汇集pool-range

除了pool-range 3-5命令max-conn参数,此配置是相同的象多个调制解调器在pool-range配置方面。

没有a的调制解调器汇集pool-range
! 
modem-pool tito 
 called-number 5557528 max-conn 0 
ip domain-name cisco.com 
isdn switch-type primary-5ess

调试与验证提示

要保证您的配置是工作正常,请使用show命令。从此should命令的输出类似于跟随的输出。

  • 在第一个拨号前的show modem-pool

    isdn2-2#show modem-pool 
    modem-pool: System-def-Mpool 
    modems in pool: 24 active conn: 1 
     3 no free modems in pool 
      
    modem-pool: tito 
    modems in pool: 0 active conn: 0 
     4 no free modems in pool 
     called_party_number: 5557528 
      max conn allowed: 0, active conn: 0 
      0 max-conn exceeded, 0 no free modems in pool
