一些cisco路由器常用的基本配置命令
1.配置主机名(全局下)
hostname xxx
2.配置接口参数(描述、配置IP、掩码、激活)
description zhegejiekoulianjieF0/0
ip addr w.x.y.z mask
no shutdow
3.安全参数(口令--特权口令又名使能口令、控制台口令、vty口令、ssh;登录横幅)
enable password ??(明文)
enable secret ??(密文---采用MD5加密算法,不可逆的---加密级别为5)
把明文口令加密--全局配置模式
- service password-encryption line console 0
- password cisco
- login(登录时检查)
- line vty 0 15(16路Telnet)
- password cisco
- login
- 3N+2K( Name---主机名、域名、用户名;key-用户key、加密key--一对)
- hostname R1
- ip domain-name byx
- username 11w1 password cisco
- crypto key generate rsa
加密数据块 1024
line vty 0 15
transport input ssh/telnet/all
login local

4.保存配置特权下:
write或者copy running-config startup-config
5.查看配置show
- show ip interface brief/show ip int b
- show interfaces/ show inter
- show interface f0/0
- show ip route /show ip ro
- show running-config /show run
- show startup-config/ show st
- show version/show ver
- show ip arp=show arp
6.路由器基本配置(主机名、接口参数)
- en
- conf t
- ho Qingdao
- int f0/0
- ip add 192.168.3.1 255.255.255.0
- no sh
- descrip Link to Qingdao LAN1
- int f0/1
- ip add 192.168.4.1 255.255.255.0
- no sh
- descrip Link to Qingdao LAN2
- int s0/0/0
- ip addr 12.0.0.2 255.0.0.0
- clock rate 64000
- no sh
- descrip Link to Yantai
7.控制台口令-----console口口令
- lin con 0
- pass cisco
- login
- telnet口令---vty口令
- lin v 0 4
- pass cisco
- logi
- 口令加密
- service password-encryption
- 特权口令
- enabl sec cisco
8.SSH-- 安全的telnet
- ip domain-name yantai.qingdao
- username byx pass cisco
- username 11w1 pass 123
- username ccna pass 123
- crypto key generate rsa
- 1024
- line vty 0 4
- transport input all
- login local
9.DHCP地址池
- ip dhcp pool LAN1
- network 192.168.3.0 255.255.255.0
- default-router 192.168.3.1
- ip dhcp pool LAN2
- network 192.168.4.0 255.255.255.0
- default-router 192.168.4.1
