一、基本配置

1、配置设备名称

我们拿到一台交换机设备默认设备名称为Huawei,右键设备启动按钮就可以启动设备，我们通过华为推荐的ENSP软件模拟器进行自学华为网络工程师。和真实设备配置几乎一样，省去购买网络设备学网络的成本。

<Huawei>//登录进去设备后 默认是用户模式

<Huawei>system-view//进入特权模式

[Huawei]sysname SW1//更改设备名称为SW1

2、配置设备系统时钟

设置时区的命令行为clock timezone XXX add | minus offset,time-zone-name用户定义的时区名，标识配置时区。add为正向偏移，minus为负向偏移。

<SW1>clock timezone BJ add 08:00//配置北京时区

配置好时区后就可以设置设备当前的日期和时间

<SW1>clock datetime ?// HH：MM：SS为时间

HH:MM:SS Specify the time

<SW1>clock datetime 12:12:12 ?//YYYY-MM-DD为日期

YYYY-MM-DD Specify the date from 2000 to 2099

<SW1>clock datetime 12:12:12 2021-12-12

配置完毕后查看显示的当前设备的日期

3、配置IP地址

我们可以通过console线连接console口、MiniUSB、及telnet登录设备配置，主流现网用的比较多的就是console和telnet,我们重点熟练使用这两个功能

1）、配置方法1

[SW1]interface MEth 0/0/1

[SW1-MEth0/0/1]ip address 192.168.1.254 255.255.255.0//配置接口IP地址192.168.1.254

2）、配置方法2

[SW1-MEth0/0/1]ip address 192.168.1.254 24//三个255可以使用24掩码长度表示

二、配置VTY telnet用户登录

1、VTY配置最大用户数

[SW1]user-interface maximum-vty ?最多允许15个用户同时telnet登录设备

INTEGER<0-15> The maximum number of VTY users, the default value is 5

2、配置VTY用户级别

[SW1]user-interface vty 0 14//进入VTY配置界面，对15个用户统一进行配置

[SW1-ui-vty0-14]user privilege level 2//配置用户级别为2

[SW1-ui-vty0-14]authentication-mode aaa//配置验证方式为aaa

3、配置AAA的用户名密码

[SW1-aaa]local-user bert password cipher bert@123//配置AAA的用户名密码

[SW1-aaa]local-user bert service-type telnet//配置类型为telnet

可以顺利telnet登录设备，测试成功后只要网络可达，其他设备就可以正常telnet登录

<SW1>display users//查看登录的用户

三、配置Console

Console一般用于管理员登录调试，所以我们配置最高的级别权限。用password验证

[SW1]user-interface console 0//进入console口进行配置

[SW1-ui-console0]user privilege level 15//配置登录级别为最高级别15

[SW1-ui-console0]authentication-mode password//配置密码认证

[SW1-ui-console0]set authentication password cipher bert@123//配置认证密码

display current-configuration 查看配置，默认配置保存在设备内存中需要save进行存盘。

[SW1]display current-configuration

sysname SW1

aaa

authentication-scheme default

authorization-scheme default

accounting-scheme default

domain default

domain default_admin

local-user bert password cipher +\[+!7+L9Q-NZPO3JBXBHA!!

local-user bert service-type telnet

local-user admin password simple admin

local-user admin service-type http

interface Vlanif1

ip address 192.168.2.254 255.255.255.0

interface MEth0/0/1

ip address 192.168.1.254 255.255.255.

user-interface maximum-vty 15

user-interface con 0

authentication-mode password

user privilege level 15

set authentication password cipher MJ%#~O(rV%'eKRQqbl+Ohg{#

user-interface vty 0 14

authentication-mode aaa

user privilege level 2
