  前言
  本文显示如何 使用一个调制解调器配置拨出在AUX 端口。在此方案,一个 路由器用一个调制解调器在AUX 端口拨号一次群速率接口(PRI)中 心站点路由器。

注意我们不表示一个备用情形,但仅仅显示 拨号请求路由选择(DDR) 拨号在路由器之间用一个调制解调器在 AUX 端口。

  欲知详情关于文件协定的,查阅 Cisco 技术提示规定。
  
  前提
  本文假设您有对多种问题的好了解联合调制解调器在 AUX 端口。如果您需要更多信息关于这些问题,参见本文 调制解调器路由器连接指南。
  
  组件使用 了
  本文的信息根据以下的软件及硬 件版本。
  
  Cisco 2600 系列路由器运 行的® Cisco IOS 软件发行12.1(2)
  
  Cisco AS5300 路由器运行的Cisco IOS 软件发行 12.0(7)T
  
  注意:此配置可以适用于所有路由器与AUX 端口甚至控制台端口。 由于RS232 调制解调器控制问题和一些安全相关的相关问 题,它没有推荐附加调制解调器控制台端口。参见 调制解调器路由器连接指南 欲知详情。

  !--- This was determined using the show line command.
  !--- See External Modem Setup and Troubleshooting Tasks for more details.
  
  no ip address
  encapsulation ppp
  
  !--- Use PPP encapsulation over this link.
  
  dialer in-band
  dialer pool-member 20
  
  !--- Designate Async65 as member of dialer pool 20.
  !--- The command dialer pool 20 is specified in interface Dialer 10.

  !--- This permits routing over the async interface.
  !--- This is required for a routing protocol to run aclearcase/" target="_blank" >ccross the async link.

  !--- Improve throughput by reducing async framing overhead
  
  speed 115200
  
  !--- The AUX port on the 2600 supports a speed of 115200.
  !--- Note: If you are routing through the AUX port, each character generates a
  !--- processor interrupt. This is an abnormally high load on the CPU, which can be
  !--- resolved by using a lower AUX port speed.
