本文为串行隧道(STUN)的直接封装提供一个配置示例。本文档的“验证”和“故障排除”部分中演示了 show stun 命令输出中的相关状态和 debug 命令输出中的状态更改。
虽然debug stun packet和debug stun event命令不应该导致CPU利用率过高, logging buffered命令用于复制输出到日志文件。
本文档没有任何特定的要求。
本文档中的信息基于Cisco IOS®软件版本12.0(8),该版本具有IBM STUN配置功能。
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始(默认)配置。如果您使用的是真实网络,请确保您已经了解所有命令的潜在影响。
有关文档规则的详细信息,请参阅 Cisco 技术提示规则。
本部分提供有关如何配置本文档所述功能的信息。
注:要查找有关本文档中使用的命令的其他信息,请使用命令查找工具(仅注册客户)。

此部分提供您能使用的,用以确认您的配置正常工作的信息。
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。
两个路由器的show stun命令输出在此部分显示。它显示每台路由器的STUN状态为打开。此外,每次您发出show stun命令,计数器收到的信息包的(rx_pkts)和已传输数据包的(tx_pkts)会增加。

注意:在发出debug命令之前,请参阅有关Debug命令的重要信息。
debug stun packet — 显示有关通过STUN链路传输的数据包的信息。
debug stun event — 显示STUN连接和活动。
