*** RFC1483 Bridging Mode Enabled *** 

Note The show version command above displays the line coding method, either CAP or DMT, for which the Cisco 678 is configured. If your service provider requires you to upgrade to a different line coding method, follow the upgrade procedure in the Release Notes for the Cisco 678 ADSL Router before proceeding with configuration.

Step 2 Enter a password when CBOS prompts you:

cbos> enable
Password:<password>
 

Note If you have not set any passwords for the Cisco 678, press the Enter key when the system prompts you for a password to enter CBOS. If you have not preset a password, you can still log on to the CBOS. You must have an exec password set in order to Telnet into the Cisco 678.

You are now in enable mode. The system prompt appears:

cbos#

Cisco also provides two methods of configuring and managing the bridged Cisco 678, through in-band bridging management or through a separate management VC. The two methods cannot be used simultaneously. If a separate management VC is used, the Cisco 678 can only be managed remotely through wan0-1 and not from the local network.

With RFC 1483 management enabled, you can manage the router using Telnet. The following commands are accessible through the managed bridge:

• ping

• telnet

• tftp

The following procedure shows how to set up the Cisco 678 for in-band bridging management.

Note You must be in the enable mode to do the procedure below. You must perform the procedure in the sequence as shown.

set bridging rfc1483 enabled
 

Step 2 To save your changes, enter:

write
 

Step 3 To reboot the device, enter:

reboot
 

set bridging management enabled <Enter>
set int eth0 address ip address
 

The IP address of the Ethernet port should be an IP address on the same network as that of the "far-end" station.

Step 5 To enable the Cisco 678 to direct management traffic to the far-end station, enter:

set route default wan0-0 <Enter>
set route default ip ip address
 

The default IP address should be the IP address of the far-end station that is used to Telnet to the router.

Step 6 To save your changes, enter:

write
 

Step 7 To enable your changes, reboot the router:

reboot
 

To manage the bridged Cisco 678 using a separate management VC, follow these steps:

set bridging management disabled
 

set bridging PVC enabled
 

Step 3 To save your changes, enter:

write
 

Step 4 To reboot the device, enter:

reboot
 

After rebooting, the Cisco 678 will have two PVCs enabled. Wan0-0 is used strictly for bridged traffic, while wan0-1 is used strictly for management traffic. Wan0-1 will be using RFC 1483 routing.

Step 5 Set an IP address on the Ethernet port that is on the same network as the far-end station out the wan0-1 interface:

set int eth0 address ip address
 

Step 6 Set the default route of the Cisco 678 to wan0-1:

set route default wan0-1
 

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

The rules that govern the bridge command are:

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

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

Step 3 Enable the DHCP server:
set dhcp server enabled

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

Step 5 Enable NAT:
set nat enabled

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

Step 7 Write the changes to NVRAM:
write

Step 8 Reboot the Cisco 678:
reboot

When the Cisco 678 reboots, configurationless provisioning is enabled.

set dhcp client disabled
 

Step 2 Disable the DHCP server:

set dhcp server disabled
 

Step 3 Disable NAT:

set nat disabled
 

Step 4 Write the changes to NVRAM:

write
 

Step 5 Reboot the Cisco 678:

reboot
 

Note After you disable the configurationless provisioning feature, you must manually configure the Cisco 678.

• 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 Guide.

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

Note When changing the Cisco 678 IP configuration, use the serial management connection to ensure you maintain your session connection to CBOS.

Step 2 To set the IP address (and your netmask), follow this example of a sample 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:

set interface eth0 mask 255.255.255.248
 

Step 3 To set the destination IP address for the WAN port, enter:

set interface wan0-0 dest 192.168.34.10
 

Step 4 To save your changes, enter:

write
 

Step 5 To allow the system to come up with these new settings, reboot the Cisco 678:

reboot
 

Step 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 Guide.

The Cisco 678 automatically trains up to the ideal line speed. By default, the Cisco 678 is provisioned with the following rates:

Encoding	Downstream/Upstream Rate (Mbps)
DMT	8.032/.864
CAP	7.168/1.088
G.Lite	1.536/.512

The maximum operative rate is determined by the Central Office ADSL equipment.

Because the Cisco 678 connects to the Cisco 6xxx series, the subscriber side VPI/VCI settings are not seen by the ATM network. All subscriber side VCs use VPI 1 by default.

Cisco 678 comes preconfigured with one VC already established. Each VC is expressed as WAN0-x, where x is a number between 0 and 3.

To set the maximum number of VCs, enter:

cbos# set interface wan0 maxvcs n
 

Table 3-2: VPI/VCI Address Ranges

VPI <count>	VPI Range	VCI Range
1	0	0..255
2	0..1	0..127
4	0..3	0..63
8	0..7	0..31

set interface wan0-1 vpi 2
 

Note If you try to enter the command set interface wan0-1 on a connection that is already open, the system prompts you to close that connection before you change the VPI setting. Close the connection by entering set interface wan0-1 close.

Step 2 To begin using this connection with the new settings, enter:

set interface wan0-1 open
 

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

Step 4 To save the new WAN port configuration, enter:

write
 

Step 5 To exit the CBOS, enter:

quit
 

set interface wan0-0 vci 4
 

Note If you try to enter the command set interface wan0-0 on a connection that is already open, the system prompts you to close that connection before you change the VCI setting. To do this, enter the command set interface wan0-0 close. Also, if there is an Ethernet packet in transmission to the wan0-0 port, the wan0-0 connection can reopen. Enter the following command to ensure the wan0-0 port remains closed during configuration set interface wan0-0 disable.

Step 2 To begin using this connection with the new settings, enter:

set interface wan0-0 open 
 

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

Step 4 To save the new WAN port configuration, enter:

write
 

Step 5 To exit the CBOS, enter:

Archives

• 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 shareware or freeware on the Internet. Cisco will provide a TFTP client upon request. TFTP client requests should be directed to the Technical Assistance Center.

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