1750做接入服务器配置实例

  用17500的aux口传异步拨号:
  (config)# line aux 0
  (config-line)# login
  (config-line)# passWord cisco
  (config-line)# speed 115200
  (config-line)# flowcontrol hardware
  (config-line)# stopbits 1
  (config-line)# transport input all
  (config-line)# modem inout
  
  再配置反向telnet:
  (config)# int lo0
  (config-if)# ip address 1.1.1.1 255.255.255.0
  (config)# ip host modem 2005 1.1.1.1
  
  用show line看到aux口的线序号是5,那么反向telnet的端口就是2000+5=2005
  
  可以用where命令查看打开的对话!
  
  上面配置好以后,将接1750上Modem设为ats0=1(最开始没有将这个设为1,所以一直拨不通!),对方的Modem就可以拨号成功,但是按回车以后还是没有反应。不能进入路由器!因为没有对异步口进行配置!
  
  要实现远程路由器治理:
  (config)# int asy 5
  (config-if)# en ppp
  (config-if)# asyn mode dedicated
  
  对远程用户分配IP地址:
  (config)# int asy 5
  (config-if)# peer default ip address 192.168.10.2
  
  需要对拨号用户使用地址池,可以这样:
  (config)# ip local pool wolf 192.168.0.50 192.168.0.254
  (config)# int asy 5
  (config-if)# peer default ip address pool wolf
  
  不过好象要重启路由器才有效!
  
  Building configuration...
  version 12.1
  service timestamps debug uptime
  service timestamps log uptime
  no service password-encryption
  !
  hostname Router
  !
  enable password cisco
  !
  memory-size iomem 25
  ip subnet-zero
  ip host modem 2005 1.1.1.1
  !
  interface Loopback0
  ip address 1.1.1.1 255.255.255.0
  !
  interface Serial0
  no ip address
  shutdown
  !
  interface FastEthernet0
  no ip address
  shutdown
  speed auto
  !
  interface Async5
  ip address 192.168.0.1 255.255.255.0
  encapsulation ppp 这个一定要!不然看到的是乱码!
  async mode dedicated 一定要!若改成async mode inter,对方拨号时总是停在检验用户名和密码那里!若两个都不设,拨号不上!
  peer default ip address 192.168.0.2
  !
  ip classless
  no ip http server
  !
  line con 0
  transport input none
  line aux 0
  password cisco
  login
  modem InOut
  transport input all
  stopbits 1
  speed 115200
  flowcontrol hardware
  line vty 0 4
  login
  !
  no scheduler allocate
  end
  
  以上配置的效果就是:对方拨号,不需要用户名和密码,连结成功,就和拨96169一样!
  
  要让拨号用户加上认证可以这样做:
  (config)# username wolf password igpwwk
  (config)# int asy 5
  (config-if)# ppp au pap
  也可以使用chap认证:
  (config-if)# ppp au chap
  或者同时使用:
  (config-if)# ppp au chap ppp (config-if)# ppp au ppp chap
  
  以下是将串口模拟成异步口:
