试验一
1
、进入特权模式
enable
2
、进入全局配置模式
configure terminal
3
、为路由器取一个名字
hostname [hostname]
4
、进入接口
interface Ethernet 0
5
、查看当前配置信息
show running-config
6
、查看
NVRAM
里面的配置信息
show startup-config
7
、查看
flash
里面的
IOS
文件信息
show flash
8
、查看系统硬件的配置信息,软件版本,配置文件的名称和来源,以及启动镜像
show version
9
、查看路由器当前时间
show clock
10
、特权模式的明文密码
Router
(
config
)
#
enable password mingwen
11
、特权模式的密文密码
Router
(
config
)
#
enable secret miwen
12
、将路由器中的所有明文密码变成加密的形式
Router
(
config
)
#
service password-encryption
13
、关闭域名解析
Router
(
config
)
#
no ip domain-lookup
14
、配置此命令后,当我们输入错误的命令时,路由不会对它进行域名解析,从而节省我们的时间。
15
、配置
con
口日志同步显示
Router
(
config
)
#line con 0
Router
(
config-line
)
#logging synchronous
16
、设置标语信息
Router
(
config
)
#banner motd #{text}#
17
、
Console
接口的安全配置
Router
(
config
)
#line console 0
Router
(
config-line
)
#password [password]
Router
(
config-line
)
#login
Router
(
config-line
)
#exit
18
、
VTY
口的配置
Router
(
config
)
#line vty 0 4
不动设备或不同
IOS
可能数量不同
Router
(
config-line
)
#password [password]
Router
(
config-line
)
#login
Router
(
config-line
)
#exit
