Configure Cisco 675/678 External Modem with the following steps:
1) Connect management cable
2) Configure External DSL modem
3) Connect WAN
4) Connect workstation or LAN
5) Configure workstations
The Cisco 675 comes with a special serial cable to connect the
serial port of a computer
to the Cisco 675 management port for out-of-band management. The
cable is gray with a DB9 connector on one end an an RJ type
modular connector on the other end. This is the only way to issue
commands to the Cisco 675 while in bridging mode. If you have
previously used your modem in routing mode, you should be able
to telnet to the modem as you have in the past. The provided
management cable should work with an Intel-based PC or similar
system which has a DB9 male COM port. Connect the DB9 end to
the PC COM port and the other end to the Cisco 675 management
port. Use Hyperterm (hypertrm.exe) or a similar program to
connect "direct to COM1" or the appropriate port at
38400bps (or 9600), 8 bits, 1 stop, no parity, no flow control.
On a Macintosh, an adapter cable is required. If the
connection doesn't work using the Mac serial port, try the parallel
port. The difference between those two ports is cross-over of RD
and TD (DCE vs. DTE). Consult your modem manual for further
information.
If you are an existing working customer with a modem in bridging
mode, DO NOT FOLLOW THESE INSTRUCTIONS. If you want to change to ppp/routing
mode, please call NeTrack. We need to make changes on our end simultaneously
to change you to routing mode, otherwise your connection won't work.
All new customer connections are configured in ppp/routing mode.
You must be running CBOS version 2.4.2 or higher. Use the CBOS
"show version" command to see your CBOS version. Earlier
versions have security vulnerabilities. If you need
to upgrade, download the firmware and follow the upgrade
instrucstions.
In the configuration instructions below, use the following substitutions:
ip_address
is the single IP address you were given or the first usable IP address in your
assigned block. For example, if you are assigned the block 192.168.15.40
through 192.168.15.47, the ip_address you
would use here is 192.168.15.41.
net_mask
is the IP block network mask given to you by NeTrack.
cr is a carriage return.
Do all of the following steps that apply. If you are
assigned static IPs (step 5), then DHCP/NAT is optional (step 4), you can use
both but you don't have to. These instructions will provide a working
configuration. If you want to use additional features, such as NAT
mapping or filters, please consult your Cisco modem manual.
1) Erase any existing configuration so we start with a clean
slate:
cbos>enable
Password:cr
cbos#set nvram erase
Erasing Running Configuration.
You must use "write" for changes to be permanent.
cbos#write
NVRAM written.
cbos#reboot
Hello!
Expanding CBOS image...
CBOS v2.4.3.000
cr

Password:cr
cbos>enable
Password:
2) [Cisco 678 only] Manually set the VPI/VCI. Use 0 and
32 for customers who are new or have moved locations since April 2001 (DMT).
Use 1 and 1 for dsl setups that have been working since before April 2001 (CAP).
The example below is for new customers.
cbos# set int wan0-0 close
cbos# set int wan0-0 vpi 0
cbos# set int wan0-0 vci 32
cbos# set int wan0-0 open
3) Set DSL modem IP address and disable remote access.
cbos#set ppp wan0-0 ipcp ip_address
PPP wan0-0 IPCP Address set to ip_address
cbos#set ppp wan0-0 dns 0.0.0.0
PPP wan0-0 DNS Server Addresses set to 0.0.0.0 cbos#set web port 9999 disabled cbos#set telnet disabled
4) Enable NAT/DHCP internally:
cbos#set nat enabled
NAT is now enabled
You must use "write" then reboot for changes to take effect.
cbos#set dhcp server enabled
DHCP Server enabled
5) [Optional] If you were assigned an IP block to use static IPs internally:
cbos#set int vip0 ip ip_address
Virtual IP Address now changed
You must use "write" then reboot for changes to take effect
cbos#set int vip0 mask net_mask
Virtual Netmask now changed
You must use "write" then reboot for changes to take effect
6) Save the config and reboot:
cbos#write
NVRAM written.
cbos#reboot
Connect WAN
Simply
connect the Cisco 675/678 WAN port to the wall telephone outlet with the normal RJ45 cable
provided with the modem. The WAN link light should light solid green. A flashing WAN link light
indicates either a problem with your cable, wall outlet, home/office wiring to
the wall outlet, or the DSL service.
If your WAN link light will not stop flashing and stay on solid,
check to make sure the Cisco 675/678is plugged directly into your
telephone line as the first thing. Plug telephones and modems into
the Cisco 675/678. Never plug the Cisco 675/678into the telephone port on a
standard modem or behind a telephone switching device. If your WAN
link light still flashes, call Qwest at 888-423-8994.
The Cisco 675/678comes with a cross-over 10baseT Ethernet cable (YELLOW). It is designed to
connect directly between the Cisco 675/678Ethernet port and the Ethernet interface on a single
computer workstation. To connect the Cisco 675/678to a 10baseT LAN hub/concentrator, the
Cisco 675/678must either be connected to a non-cross-over uplink port on the hub using the
cross-over cable provided or connected to a regular node port on the hub using a regular
non-cross-over 10baseT cable (not provided).
Configure all workstations to get their IP address dynamically unless
there is a specific requirement for a static IP address. If you have
requested and been assigned a block of static IP addresses, you may use any
IP address in the block except that which are already in use by the DSL
675/678 when you configured it above, in use by another workstation you
already configured, or the very first and last IP in the block. Please refer to the Mac and Windows specific configuration notes.
