Important: Before you begin, close all programs on the PC that might be monitoring your COM port. Devices such as PDAs and digital cameras often place programs in the system tray that render your COM port unusable for the configuration of your Cisco DSL Router.
Connect the Cisco DSL Router and Your PC
A console connection is made with a rolled cable and connects the console port of the Cisco DSL Router to a COM port on a PC. The console cable that is included with the Cisco DSL Router is a flat light blue cable. For more information on the pinouts of a rolled cable, or the pinouts of an RJ-45 to DB9 converter, refer to Cabling Guide for Console and AUX Ports.
1.Connect the RJ-45 connector on one end of a Cisco console cable to the console port of the Cisco DSL Router.
2.Connect the RJ-45 connector at the other end of the console cable to an RJ-45 to DB9 converter.
3.Connect the DB9 connector to an open COM port on your PC.
Start and Set Up HyperTerminal
Complete these steps:
1.Start the HyperTerminal program on the PC.
2.Set up your HyperTerminal session.
a.Assign a name to your session and click OK.
b.In the Connect To window, click Cancel.
c.Choose File > Properties.
d.From the Properties window, go to the Connect Using list and select the COM port where you connect the DB9 end of the console cable.
e.From the Properties window click Configure and fill in these values:
■Bits per second: 9600
■Data bits: 8
■Parity: None
■Stop bits: 1
■Flow Control: None
f.Click OK.
g.From the Call menu, click Disconnect.
h.From the Call menu, click Call.
i.Press Enter until you see a router prompt on your HyperTerminal window.
Clear Existing Configurations on the Cisco DSL Router
Complete these steps:
1.Type enable at the router prompt in order to enter privileged mode.
Router>enable
Router#
!--- The # symbol indicates that you are in privileged mode.
2.Clear existing configurations on the router.
Router#write erase
3.Reload the router so that it boots with a blank startup configuration.
Router#reload
System configuration has been modified. Save? [yes/no]:no
Proceed with reload? [confirm]yes
!--- The router reload can take a few minutes.
4.After the router has reloaded, enter enable mode again.
Router>enable
Router#Configure the Cisco DSL Router
Complete these steps:
1.Configure service timestamp to properly log and display debug output in the troubleshooting section.
Router#configure terminal
Router(config)#service timestamps debug datetime msec
Router(config)#service timestamps log datetime msec
Router(config)#end
2.Disable the logging console on your Cisco DSL Router in order to suppress console messages that might be triggered while you configure the router.
Router#configure terminal
Router(config)#no logging console
Router(config)#end
3.Configure ip routing, ip subnet-zero, and ip classless in order to provide flexibility in routing configuration options.
Router#configure terminal
Router(config)#ip routing
Router(config)#ip subnet-zero
Router(config)#ip classless
Router(config)#end
4.Configure the global Point-to-Point Protocol over Ethernet (PPPoE) parameters.
Router#configure terminal
Router(config)#vpdn enable
Router(config)#no vpdn logging
Router(config)#vpdn-group pppoe
Router(config-vpdn)#request-dialin
Router(config-vpdn-req-in)#protocol pppoe
Router(config-vpdn-req-in)#end
5.Configure an IP address and subnet mask on the Cisco DSL Router Ethernet interface.
For Network Address Translation (NAT): Optional) Enable NAT inside on the Ethernet interface.
Router#configure terminal
Router(config)#interface ethernet 0
Router(config-if)#ip tcp adjust-mss 1452
!--- If the ip tcp adjust-mss 1452 command is not supported, try
!--- ip adjust-mss 1452. If this command is not supported,
!--- upgrade to the latest Cisco DSL Router software or follow the
!--- procedure in Possible Required Configuration Steps on the PC.
Router(config-if)#ip address
!--- For NAT:
Router(config-if)#ip nat inside
Router(config-if)#no shut
Router(config-if)#end
6.Configure the ATM interface of your Cisco DSL Router with an ATM permanent virtual circuit (PVC), encapsulation type, and dialer pool.
Router#configure terminal
Router(config)#interface atm 0
Router(config-if)#pvc
Router(config-if-atm-vc)#pppoe-client dial-pool-number 1
Router(config-if-atm-vc)#no shut
Router(config-if-atm-vc)#end
7.Configure the Dialer interface of your Cisco DSL Router for PPPoE with a static IP address.
For NAT: (Optional) Enable NAT outside on the Dialer interface.
Router#configure terminal
Router(config)#interface dialer 1
Router(config-if)#mtu 1492
Router(config-if)#ip
Router(config-if)#no ip directed-broadcast
!--- For NAT:
Router(config-if)#ip nat outside
Router(config-if)#encapsulation ppp
Router(config-if)#dialer pool 1
Router(config-if)#ppp chap hostname
Router(config-if)#ppp chap password
Router(config-if)#ppp pap sent-username
Router(config-if)#end
8.Configure a default route using Dialer1 as the outbound interface.
Router#configure terminal
Router(config)#ip route 0.0.0.0 0.0.0.0 dialer1
Router(config)#end
9.For NAT: Configure global NAT commands on the Cisco DSL Router to allow sharing of the dynamic public IP address of the Dialer interface.
Router#configure terminal
Router(config)#ip nat inside source list 1 interface Dialer1 overload
Router(config)#access-list 1 permit
Router(config)#end
Optional Configurations
NAT Pool, if additional IP addresses have been provided by your ISP.
Router(config)#ip nat inside source list 1 interface dialer1 overload
Router(config)#ip nat pool
Router(config)#end
Static NAT, if Internet users require access to internal servers.
Router(config)#ip nat inside source static tcp
{80 or 25}
Router(config)#end
10.For Dynamic Host Configuration Protocol (DHCP): (Optional) Configure the Cisco DSL Router as a DHCP server with a pool of IP addresses to assign to hosts connected to the Ethernet interface of the Cisco DSL Router. The DHCP server dynamically assigns an IP address, Domain Name Server (DNS), and the default gateway IP address to your hosts.
Router#configure terminal
Router(config)#ip dhcp excluded-address
Router(config)#ip dhcp pool
Router(dhcp-config)#network
Router(dhcp-config)#default-router
Router(dhcp-config)#dns-server
Router(dhcp-config)#end
11.Enable logging console on the Cisco DSL Router, and then write all the changes to memory.
Router#configure terminal
Router(config)#logging console
Router(config)#end
*Jan 1 00:00:00.100: %SYS-5-CONFIG_I: Configured from console by console
Router#write memory
Building configuration... [OK]
