简介

在一些环境中,可能会需要使用聚合带宽将多条异步链路绑定为单一链路。本文档介绍如何配置思科 2500 接入服务器以使用虚拟模板捆绑两个异步接口。

此配置可用于通过异步线路与外置调制解调器连接或使用网络模块(内置调制解调器)的路由器。您可以根据需要向此配置中添加其他功能。

先决条件

要求

本文档没有任何特定的前提条件。

使用的组件

要实施此配置,您必须进行以下配置:

  • 在路由器 1 上创建一个多链路虚拟模板号码。

  • 在这两个路由器上的接口下配置 ppp 多链路

  • 在两个路由器的接口下配置身份验证。

在本文档中使用的配置中,路由器 1 配置为仅接听电话,路由器 2 发起通话并连接至路由器 1。两个路由器都进行了多链路 PPP 配置。当连接运行时,系统将创建主捆绑,并且两个异步链路将捆绑在一个虚拟接入接口下。

在路由器1only接收异步呼叫。ï ¿  ½的接口9和10不发现是正常的接口9和10,当他们是时一部分的异步组1.肯定创建多链路虚拟模板;否则,第一个信道上也许能进行连接,但是不会传递流量(IP控制协议 [IPCP] 已关闭)。没有虚拟模板和多链路 PPP 的情况下,此配置可用于一个异步连接,但不能同时用于两个连接。

路由器 2 上的接口 2 和 3 配置了 physical-layer async 命令,且会接受多链路 PPP 命令。这些接口变为拨号循环组的一部分时,将被自动移除。输入 dialer rotary-group 3 命令之后,serial ppp multilink 命令会立即从配置中删除。请改用接口 dialer 3 下的 ppp multilink 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 ppp negotiation - 用于查看客户端是否正在传递 PPP 协商;此命令用于检查地址协商。

  • debug ppp authentication -看见客户端可以是否通过认证。如果您使用的是 11.2 之前的 Cisco IOS 软件版本,请改用 debug ppp chap 命令。

  • debug ppp error - 显示和PPP连接协商与操作相关的协议错误以及统计错误。

  • debug vtemplate - 用于显示虚拟模板克隆以形成虚拟访问接口。

  • debug ppp multilink events - 用于查看 PPP 多链路事件调试。显示与影响多链路组的事件有关的信息。

  • debug dialer - 用于显示关于拨号接口上接收的数据包的调试信息。

  • show caller - 显示连接的统计或调试信息。

  • show dialer - 显示为DDR配置的接口的一般诊断信息。

  • show caller user - 显示关于哪个用户在使用哪个调制解调器端口的列表。

  • show ppp multilink - 用于查看多链路捆绑的成员。
