简介
作为路由和交换领域真正的无冕之王，Cisco公司设立了一系列认证考试，以保证使用、管理或提供Cisco产品服务的技术人员能够具备相应的技术水平，而其考试目标和内容随其产品不断地发生变化。为覆盖其最新的考试目标，我们采用“原版引进，重新排版印刷”的方式以最快的速度出版Cisco认证考试系列相应科目的辅导丛书来满足读者的需求。本书作为系列中的一本，针对CCNP：642-831考试而推出。书中的内容从故障诊断方法论开始，首先介绍了配置表和拓扑图，OSI参考模型及面向连接和无连接的协议，接着介绍了Cisco内置诊断工具的使用，串行连接和帧中继连接，之后是ISDN和相关协议及Catalyst系列交换机，最后以一个综合全书知识的现实世界的例子作为结尾。全书每一章后均有大量复习题和答案，其篇幅得当内容新颖实用，不仅适用于网络管理人员、网络设计和开发人员，更是CCNP应试人员的必备材料。
