**课程名称**: CCNA：网络入门 **课程概述**: 本课程旨在为你打下坚实的网络基础，内容涵盖 CCNA 认证的第一个核心模块。课程包含两大部分： 1. **理论讲解**: 十三段视频深入浅出地介绍了 OSI 和 TCP/IP 两种通信模型，包括它们的对比、各层的功能以及每层所使用的关键协议。这将为你构建全面的网络认知框架。 2. **实践操作**: 十一段视频提供详细的步骤演示，指导你如何对思科（Cisco）交换机和路由器进行配置。 **通过本课程，你将能够**: * **理解网络设备与服务**: 描述并区分支持数据网络通信的各种设备和服务。 * **掌握协议作用**: 解释协议在数据网络中的角色和重要性。 * **掌握以太网概念**: 阐述基本以太网工作原理。 * **理解进制转换**: 熟练运用二进制、十进制和十六进制，并进行相互转换。 * **评估寻址重要性**: 理解 IP 地址、MAC 地址和端口地址在网络中的关键作用。 * **应用 IP 地址**: * 使用 IPv4 地址配置路由器等网络设备。 * 使用 IPv6 地址配置路由器等网络设备。 * 设计、计算并应用子网掩码和地址，满足 IPv4 和 IPv6 网络的需求。 * 通过子网划分，包括可变长子网掩码（VLSM），解决 IPv4 地址短缺问题。 * 区分 IPv4 地址类型（单播、组播、广播）。 * 区分 IPv6 地址类型（全局单播、组播、链路本地）。 * **构建与配置网络**: * 使用路由器和交换机搭建一个简单的以太网网络。 * 掌握思科设备 IOS 命令行的基本导航和使用。 * 利用思科 IOS 的帮助功能。 * 在思科路由器和交换机上配置基本安全策略。 * 配置 Telnet 和 SSH 连接，实现远程管理。 * 在思科路由器上配置静态路由和默认路由，实现跨网络数据包转发。
This course will cover the concept of the first CCNA course with a hands-on portion. There are thirteen videos explaining both OSI and TCP/IP communication models; comparing the two communication models; describing each layer of the communication models and protocols residing in each layer to create a foundation for understanding networking concept. The concept is complemented with eleven videos with step-by-step demonstration for configuring both Cisco switches and routers.After completing this course, you will be able to:Describe and differentiate the devices and services used to support communications in data networks.Describe the role of protocols in data networks.Explain fundamental Ethernet concepts.Explain binary, decimal, and hexadecimal numbering systems in addition to converting a number from one numbering system to another.Evaluate the importance of addressing in data networking.Understand Port, IP, and MAC addressing.Understand and use IPv4 addresses to configure networking devices such as routers.Understand and use IPv6 addresses to configure networking devices such as routers.Design, calculate, and apply subnet masks and addresses to fulfill given requirements in IPv4 and IPv6 networks.Apply subnetting IPV4 network addresses to deal with IPv4 shortage.Apply Variable Length Subnet Masking (VLSM) for IPv4 network addresses to overcome IPv4 shortage.Describe different types of IPv4 addresses such as unicast, multicast, and broadcast addresses.Describe different types of IPv6 addresses such as global unicast, multicast, and link-local addresses.Build a simple Ethernet network using routers and switches.Use Cisco command-line interface (CLI) commands to navigate Cisco device IOS modes.Configure basic security on both Cisco routers and switches.Use Cisco IOS HELP features for both Cisco routers and switches.Configure Telnet on both Cisco routers and switches.Configure SSH on both Cisco routers and switches.Configure static and default routes on Cisco routers to allow forwarding packets to remote networks in an internetwork.
