 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 
banner motd #??????????????# 
motd:message of the day 
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
