【内容简介】

　　《Cisco局域网交换技术(英文版)》综合了在现代校园网中设计、利用和部署局域网交换设备及技术的最佳方法。全书分为六个部分，通过提供一系列已经证实的设计模型、实际实现解决方案和疑难解析策略，使我们了解了基本的交换概念范围之外的很多东西。第一部分讨论了重要的基础性问题，为后面的章节打下了基础。这一部分内容包括快速和吉比特以太网、路由选择和交换的比较、Layer2交换技术的类型、Catalyst命令行环境以及VLAN等。第二部分详细讨论了已发布的生成树协议，其中包括常见问题、疑难解析以及像PortFast、UplinkFast、BackboneFast和PVST+这样的改进技术。第三部分讨论了中继线连接中的关键问题以及用来在校园网中承载多个VLAN的链路。所有的章节都专门讨论LANE和MPOA的问题。第四部分提供了像Layer3交换技术、VTP、CGMP和IGMP这样的高级特性。第五部分则讲述了实际的校园网设计以及实现过程中遇到的问题，你可以从该部分中局域网交换技术专家的建议中获益。最后一部分讨论了Catalyst6000/6500交换机系列中的问题，其中包括Layer3交换技术中功能强大的NativeIOSMode。
　　《Cisco局域网交换技术(英文版)》是网络工程师准备CCIE考试交换部分的权威指南。《Cisco局域网交换技术(英文版)》也适合要详细了解局域网交换技术的网络管理员、网络工程师、网络设计师以及网络项目经理阅读。
