Cisco 678 Configuration for Qwest DSL Circuits (With Subnet)
 
Web www.seanet.com

The router should have the power cable plugged in and the managment cable connected between the MGMT port on the router and a serial port on the PC. If you are on a Mac you will need adapters from the serial plug (DB-9) to a modem port plug (DB-25) on the Mac. The management cable interface needs to be used the first time you configure the router because the ethernet port hasn't been configured yet.

  • Wiring:
    • The router should be connected to the wall by a regular phone cord.
    • There should not be any filters between the router and the wall. (The filters that Qwest provides are small black, in-line filters about the size of your finger. They also send a wall jack with a built-in filter.) The filters are for all the non-DSL devices atttached to the same line as the DSL.
    • To connect the router to a computer use a crossover cable. The yellow cable that Qwest provides is a crossover cable.
    • To connect the router to a hub use a straight through cable.

  • HyperTerminal (Windows) can be used to connect to the router:
    • Name the new connection Cisco675.
    • Set terminal program for correct serial port (Select direct to ComX (X is the port number) on the screen that asks you for the phone number, etc.).
    • Configure for 38,400 baud, N, 8, 1, NO flow control.


Open a connection to the router and hit enter. You should be prompted with:

User Access Verification
Password:

Hit enter for the password.

cbos> enable
Password:

Hit enter for the password.

cbos# set bridging rfc1483 disabled
cbos# set bridging management disabled
cbos# set nvram erase
cbos# write
cbos# reboot

Hit enter and you should be prompted with:

User Access Verification
Password:

Hit enter for the password.

cbos> enable
Password:

Hit enter for the password.

cbos# set ppp wan0-0 login SeanetLogin
cbos# set ppp wan0-0 password SeanetPassword
cbos# set ppp restart enabled
cbos# set int eth0 address FirstUsableIP
cbos# set int eth0 mask Mask

The mask is determined by the size of the subnet.
Subnet Size Mask
8 255.255.255.248
16 255.255.255.240
32 255.255.255.224
64 255.255.255.192
128 255.255.255.128
256 255.255.255.0


You should protect the router from unauthorized access from outside. These passwords are for access to the router's configuration. You will need to remember the passwords to access the router in the future to troubleshoot or reconfigure it.

To set the password used for "User Access Verification:"

cbos# set password exec password


It may be necessary to configure the router to use DMT.

To set the router for DMT rather than CAP mode:

cbos# set interface wan0-0 disable
cbos# write
cbos# set interface wan0-0 vpi 0
cbos# set interface wan0-0 vci 32
cbos# write
cbos# set interface wan0-0 enable
cbos# write
cbos# set interface wan0 retrain



The configuration must be saved and the router rebooted:

cbos# write
cbos# reboot

Do a quick ping test from the router. The router must be in enable mode to ping.

Hit enter and you should be prompted with:
User Access Verification
Password:

cbos> enable
Password:

cbos# ping 199.181.164.1

You will get a ping response if the DSL connection is up.
