注意!GNS3 的版本号和 GNS3 IOU VM 的版本号必须一致!否则两者无法协同工作!

比如:GNS3 的版本是 1.5.3 ,那么 GNS3 IOU VM 的版本也必须是 1.5.3 ;如果 GNS3 是 1.5.3 ,而 GNS3 IOU VM 是 2.0.0 ,那么它们之间是无法协同工作的!

GNS3 是一款具有图形化界面可以运行在多平台(包括 Windows 、Linux 和 MacOS 等)的网络虚拟软件。Cisco 网络设备管理员或是想要通过 CCNA 、CCNP 和 CCIE 等 Cisco 认证考试的相关人士可以通过它来完成相关的实验模拟操作。同时它也可以用于虚拟体验 Cisco 网际操作系统 IOS 或者是检验将要在真实的路由器上部署实施的相关配置。

简单说来它是 dynamips 的一个图形前端,相比直接使用 dynamips 这样的虚拟软件要更容易上手和更具有可操作性。

GNS3 整合了如下的软件:

  • Dynamips :一款可以让用户直接运行 Cisco 系统( IOS )的模拟器
  • Dynagen :是 dynamips 的文字显示前端
  • Pemu :PIX 防火墙设备模拟器
  • Winpcap :Windows 平台下一个免费、公共的网络访问系统,开发 winpcap 这个项目的目的在于为 win32 应用程序提供访问网络底层的能力

GNS3 的特点:

  • 设计优秀的网络拓扑结构
  • 模拟 Cisco 路由设备和 PIX 防火墙
  • 仿真简单的 Ethernet 、ATM 和帧中继交换机
  • 能够装载和保存为 dynamips 的配置格式,也就是说对于使用 dynamips 内核的虚拟软件具有较好的兼容性
  • 支持一些文件格式( JPEG 、PNG 、BMP 和 XPM )的导出
