After you logon to CBOS and before proceed any further with your configuration process, check the version of the CBOS to verify the version number and date reflect the most recent firmware update: cbos# show version.

1. Type enable at the exec mode command line:
cbos>
cbos> enable

2. Enter a password when CBOS prompts you:

Cisco also provides a method of configuring and managing the bridged 676 by enabling a management mode. With rfc1483 management enabled, you can manage the router using telnet. The following commands are accessable through the managed bridge:

• ping

• telnet

The following procedure shows how to set up the 676 for bridging management.

The IP address that is assigned to the router, must be an IP address that is on the same network segment (subnet) that is being bridged. Assigning IP addresses in this fashion enables access via telnet, to the router for management functions.

For more information on using the set bridging command, see the Cisco Broadband Operating System User's Guide.

The rules that govern the bridge command are:

If you choose bridging as your connection mode, see also the following sections:

1. Enable the DHCP client:
set dhcp client enabled

2. To check whether this feature is enabled, enter the following command:
show dhcp client

3. Enable the DHCP server:
set dhcp server enabled

4. To check whether this feature is enabled, enter the following command:
show dhcp server

5. Enable NAT:
set nat enabled

6. To check whether this feature is enabled, enter the following command:
show nat

7. Write the changes to NVRAM:
write

8. Reboot the 676:
reboot

When the 676 reboots, configurationless provisioning is enabled.

1. Disable the DHCP client:
set dhcp client disabled

2. Disable the DHCP server:
set dhcp server disabled

3. Disable NAT:
set nat disabled

4. Write the changes to NVRAM:
write

5. Reboot the 676:
reboot

• set dhcp server binding

• set dhcp server pool

• set dhcp client port

• set nat entry add

• set nat entry delete

• set nat timeout

• set nat outside

For a complete description of each of these commands, see the Cisco Broadband Operating System User's Manual.

You must be in the enabled mode to do this procedure.

1. Logon to the CBOS (cbos# ) using the serial connection.

2. To set the IP address (and your netmask), follow the example of the following command:
set interface eth0 address 192.168.34.9

The IP address becomes 192.168.34.9 and the netmask becomes 255.255.255.0 by default. If you wish to explicitly set the netmask, enter the following command:
set interface mask 255.255.255.248

3. To set the destination IP address for the WAN port, enter the following:
set interface wan0-0 dest 192.168.34.10

4. To save your changes, enter:
write

5. To allow the system to come up with these new settings, reboot the Cisco 676 by entering:
reboot

6. Log back on to the CBOS to continue.

For more detailed information on the set interface command, see the Cisco Broadband Operating System User's Guide.

Cisco 676 comes pre-configured with one VC already established. Each VC is expressed as WAN0-x, where x is a number between one and four.

To set the maximum number of VCs, enter
cbos# set interface wan0 maxvcs <n>

2. To begin using this connection with the new settings, enter:
set interface wan0-1 open

3. Repeat steps 1 and 2 for every VPI assignment you want to make.

4. To save the new WAN port configuration, enter:
write

5. To exit the CBOS, enter:
quit

2. To begin using this connection with the new settings, enter:
set interface wan0-0 open

3. Repeat steps 1 and 2 for every VCI assignment you want to make.

4. To save the new WAN port configuration, enter:
write

5. To exit the CBOS, enter:
quit

For more information on configuring VPI/VCI address mapping, see the Cisco Broadband Operating System User's Guide.

For more information on using the set route command, see the Cisco Broadband Operating System User's Guide.

To disable RIP, enter:

set rip disabled 

For more information on using the set rip commands, see the Cisco Broadband Operating System User's Guide.

1. To block all packets going through the Ethernet interface, enter:
set filter 0 on deny eth0 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0

2. To check whether this feature is enabled, enter the following command:

show dhcp server
 

3. Write the changes to NVRAM:

write
 

4. Reboot the 676:

reboot

For more information on using DHCP servers, see the set dhcp server series of commands in Cisco's Broadband Operating System User's Manual.

The Cisco 676 has been successfully tested for compatibility with the following RADIUS server providers:

• Livingston Enterprises RADIUS 2.01

• Sun Solaris 2.5

• Merit RADIUS (Sun binary)

• RADIUS NT (Microsoft)

set ppp wan0-0 radius enabled
set ppp wan0-0 login cisco
set ppp wan0-0 password is_great
 

The Cisco 676's default configuration for RADIUS appears.

For more information on RADIUS commands, see the Cisco Broadband Operating System User's Guide.

• When using the put option of the tftp command, you must name the file nscfg.cfg.

• When using the get option of the tftp command, name the file any name that a standard text editor can view and edit.

Windows 95/98 does not have a TFTP client. If you want to utilize TFTP on a Windows 95/98 system, you must install a TFTP client from a third-party vendor on your system. One way to locate a TFTP client is to use an Internet search engine to locate a vendor who sells a TFTP client. Some TFTP clients are provided as share or freeware on the Internet. Cisco will provide a TFTP client upon request. TFTP client requests should be directed to Technical Assistance Center.

For more information on TFTP commands, see the Cisco Broadband Operating System User's Guide.
