cisco路由器实验报告Cisco路由器实验报告引言：在现代网络通信中，路由器是一个至关重要的设备。

它能够将数据包从源地址传输到目的地址，实现网络之间的连接和数据传输。

本实验旨在研究和探索Cisco路由器的功能和应用。

一、Cisco路由器的基本原理Cisco路由器是一种网络设备，它基于OSPF（开放最短路径优先）协议和BGP （边界网关协议）等路由协议工作。

其基本原理是将数据包从一个网络传输到另一个网络，通过查找路由表中的最佳路径来实现。

二、Cisco路由器的配置与管理1. 登录和基本设置通过串口或以太网口与路由器建立连接后，可以通过命令行界面（CLI）或Web 界面登录路由器进行配置和管理。

首次登录需要进行基本设置，如设置主机名、密码、IP地址等。

2. 路由配置路由配置是Cisco路由器的核心功能之一。

通过配置静态路由或动态路由协议，路由器可以学习到网络拓扑，并根据路由表进行数据包转发。

静态路由适用于小型网络，而动态路由协议适用于大型网络。

3. 接口配置路由器的接口配置非常重要，它决定了路由器与其他设备之间的连接方式和速率。

可以通过配置IP地址、子网掩码、MTU（最大传输单元）等参数来进行接口配置。

4. 安全性配置为了保护网络安全，Cisco路由器提供了多种安全功能和配置选项。

例如，可以配置访问控制列表（ACL）来限制特定IP地址的访问，还可以启用SSH（安全外壳协议）来加密远程登录会话。

三、Cisco路由器的高级功能1. VLAN（虚拟局域网）通过配置VLAN，可以将一个物理网络划分为多个逻辑网络，提高网络的灵活性和安全性。

Cisco路由器支持VLAN的创建和管理，可以实现不同VLAN之间的通信。

2. VPN（虚拟专用网络）VPN是一种通过公共网络建立安全连接的技术。

Cisco路由器支持IPSec （Internet协议安全）和SSL（安全套接字层）等VPN协议，可以实现远程办公和跨地域网络连接。

网络工程师考什么证比较好在当今信息时代，网络工程师的需求越来越大，成为了一个备受追捧的职业。

Lab 1.3.3 Determining the Screen Resolution of a ComputerObjectives•Determine the current screen resolution of a PC monitor. •Determine the maximum resolution for the highest color quality. •Calculate the number of pixels needed for resolution settings. • Identify the type of monitor and graphics card installed.Background / PreparationThe resolution of a monitor determines the quality of the screen display. The resolution is determined by the number of horizontal and vertical picture elements (pixels) that are used to produce the image on the monitor. The number of pixels is typically predefined by the manufacturers of graphics cards and PC monitors. The highest number of pixels that a monitor and graphics card can support is referred to as maximum resolution. An example of maximum resolution is 1280 x1024, which means the display is composed of 1280 horizontal pixels and 1024 vertical pixels. The higher the resolution is set, the sharper the display image. The maximum resolution of a PC monitor and the number of colors the monitor can display are determined by two factors:•Capability of the monitor •Capability of the graphics card, especially the amount of onboard memory The following resources are required:• Computer with Windows XP installed Step 1: Determine the current screen resolutiona. To view the current screen resolution and color quality settings, right-click on any empty space on thedesktop and select Properties from the context menu. In the Display Properties window, select the Settings tab.You can also access Display Properties by opening the Control Panel and clicking the Displayicon.CCNA DiscoveryNetworking for Home and Small Businesses v4.0: Personal Computer Hardwareb. Use the Display Properties Settings tab to record the current settings on your PC:The screen resolution is (H by V) ______________________________________________The horizontal resolution is: __________________________________________________The vertical resolution is: ____________________________________________________The color quality value is: ____________________________________________________Step 2: Determine the maximum resolution for the highest color qualityThe slide bar under Screen resolution is used to configure the desired resolution.a. Move the slide bar to see the range of screen resolutions that are available on your PC. (The range isdetermined by the operating system when it identifies the display card and the monitor.)b. Use the Display Properties Settings tab to fill out the following table for the current settings on yourPC:Minimum screen resolutionMaximum screen resolutionAvailable color quality settingsStep 3: Calculate the pixels for current and maximum resolution settingsThe display on the screen consists of rows of pixels. The number of pixels in each row is the horizontal resolution. The number of rows is the vertical resolution. To determine the total number of pixels in a screen resolution, you multiply the horizontal resolution by the vertical resolution. For example, if the currentresolution is 1280 x 1024, the total number of pixels is 1280 times 1024, or 1,310,720.a. Calculate the total number of pixels for the lowest resolution: ___________________________b. Calculate the total number of pixels for the maximum resolution: ________________________ Step 4: Identify the type of graphics card installedYou can get detailed information about the graphics card (also called the display adapter) in the Display Properties screen.a. In the Display Properties screen, click the Advanced button.b. Select the Adapter tab.c. Use the information found in the Adapter tab to complete the following table:Graphics card manufacturer and model(Adapter Type)Graphics memory on card(Memory Size)Step 5: Identify the type of monitor and available refresh ratesYou can get detailed information about the monitor in the Display Properties screen. The screen refresh rate determines the number of times per second the screen is illuminated or redrawn. A refresh rate of 60 hertz means the screen is illuminated 60 times per second. Higher refresh rates provide less screen flicker, which reduces eye strain, but may adversely affect the monitor. You should set the refresh rate to the highest level the monitor can safely support.a. Click on the Monitor tab to see the monitor type and current refresh rate.b. Use the information found in the Monitor tab to complete the following table:Monitor typeSupported refresh ratesc. What can occur if you select a refresh rate that is higher than what the monitor can safely display?____________________________________________________________________________。

On PC1, type nbtstat –n and press Enter to see the local NetBIOS name of PC1.b. On PC2, type the same command to verify the NetBIOS name is set to PC2.c. The nbtstat –a command can be used to look at a remote computer’s name table. Type nbtstatagain from the command prompt. Notice in the output that when you use the –a switch, you have toput a space and then type a remote computer’s name (RemoteName).From PC1, type nbtstat –a PC2 and press Enter. The nbtstat information for PC2 shows on PC1’smonitor.What command would be used from the command prompt on PC2 to view information about PC1?____________________________________________________________________________d. From PC2, type the appropriate command to view PC1’s nbtstat information.e. The nbtstat –A (notice that the switch is a capital A this time) can be used to view the sameinformation using an IP address rather than a name. If you type nbtstat again, you can see that thecommand syntax tells us that we use –A followed by an IP address. The IP address is that of theremote computer.From PC1, type nbtstat –A 192.168.10.3 to see the same information that was returned by thenbtstat –a PC2 command.f. Write the command that would be typed on PC2 to view information about PC1, using the IP addressof PC1 instead of the NetBIOS name. _____________________________________________g. From PC1, you can use the ping command to verify connectivity. However, instead of using an IPaddress, you can use the NetBIOS name. From the PC1 command prompt, type ping PC2 (noticethe capitalization). The result should be successful.h. From PC1, type ping pc2 (notice the capitalization).i. Does the ping succeed using lower case letters? ______________________________________j. You can use the nbtstat –r command to see NetBIOS names that have been resolved (they are known). From the PC1 and PC2 command prompt, type nbtstat –r to see that the remote computer isknown using NetBIOS.k.
