前 言

1. 软考网络工程师在 2018 年 2 月 1 日出书教程《网络工程师教程 第 5 版》,其间网络设备从本来的思科改为华为。

2. 依据教程第 10 章组网技能的内容,并依据以往历年的真题考试 剖析,编写这本试验指导书。




试验一 VRP 根底操作与 Telnet 装备

知识点 :

n VRP (通用路由渠道)是华为公司数据通信产品的通用网络操作体系渠道,具有共同的网 络界面、用户界面和办理界面。

n 在 VRP 操作体系中,用户经过指令行对设备下发各种指令来完成对设备的装备及日常 保护操作。

n 用户登录到路由器后呈现指令行提示符后,即进入指令行接口 CLI (Command Line Interface) 。

n 装备界面分为用户视图、体系视图和各目标的装备视图

n 华为设备也支撑多种装备方法,包含 Web 界面办理等。

网络拓扑图:

操作过程

1.运用用户视图检查根本参数

用户视图下只能运用观赏和监控级指令,如运用 display

2.视图间的切换

在用户视图下候车室的故事第一部运用 system-view 指令能够切换到体系视图。在体系视图下能够装备接口、

协议等,运用 quit 指令又能够切换回用户视图。

[Huawei] //Ctrl+Z system-view

Enter system view, return user view with Ctrl+Z. [Huawei]quit

system-view

Enter system view, return user view with Ctrl+Z. [Huawei]return

3.运用 interface 指令进杨崇生入接口视图

在接口视图下能够运用 ip address 指令装备接口 IP 地址、子网掩码

system-view

Enter system view, return user view with Ctrl+Z. [Huawei]interfaceGigabitEthernet 0/0/0 [Huawei-GigabitEthernet0/0/0]ip address 192.168.0.254 24 [Huawei-GigabitEthernet0/0/0]return

4.指令行协助

假如用户忘掉指令的参数或要害字,可运用指令行在线协助。指令行在线协助分为彻底

协助和部分协助。

1. 彻底协助:

a) 恣意指令视图下,输入"? "获取该指令视图下一切的指令及其简略描绘。

b) 如在体系视图下,输入"? "获取该指令视图下一切的指令及其简略描氤氲,撕裂人-大大方方随时能够揭露的爱情,爱情三十六计述。也能够输入一 个指令,后接以空格分隔的"? "天辰列出悉数要害字或参数及其简略描绘。如在体系视图下,列

出 interface 指令参数及其简略描绘。

2. 部分协助:

a) 输入一字符串,这以后紧接"? "列出以该字符串最初的一切氤氲,撕裂人-大大方方随时能够揭露的爱情,爱情三十六计要害字。如在体系视图下列出

以"rou" 字符串最初的一切指令及其简略描绘。

3. 快捷键运用

a) 指令行接口供给了根本的指令修正功用,支撑多行修正,每条指令的最大长度为 256 个 字符。各功用键详细描绘如下:

b) 退格键表明删去光标方位的ui规划训练前一个字符:

c) 左光标键<←>或表明光标向左移动一个字符方位;

d) 右光标键<→>或表明光标向右移动一个字符方位;

e) 删去键表明删去光标方位字符;

f) 上下光标键<↑>、<↓>表明显现前史指令;

g)杭州东站 当用户输入不完整的要害字后按下键,体系主动履行部分协助,将指令补全。 比方输入" dis " 后,按键能够将指令补全为" display " ;

9.保存装备

save

The current configuration will be written to the device. Are you sure to continue? (y/n)[n]:y

It will take several minutes to save configuration file, please wait.......

Configuration file had been saved successfully

Note: The configuration file will take effect after being activated

考虑和扩展

1、假如装备完成后不保存,会发作什么?

每次装备完成后,假如不保存装备,装备会丢掉,路由器重启后,会康复到原先装备前

的状况,乃至是出厂设置状况,所以每次装备完成后,保存装备应是一个习气。

2、怎么暂时封闭一个接口?接口封闭时,状况显现是什么?

封闭接口的指令是 shutdown,假如接口封闭了,要从头敞开,需要在接口下运用 undo

shutdown 指令创业好项目,假如接口封闭了,状况显现如下:
