cisco 路由的基本配置命令

  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
  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.

  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
