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!

要实现远程路由器管理:

(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:
