Configuring the Cisco 675 for Use with the Cisco 6200

Configuring the Cisco 675 for Use with the Cisco 6200

This appendix tells you how to configure the Cisco 675 ADSL customer premises equipment (CPE) for use with the Cisco 6200 advanced digital subscriber line access multiplexer (DSLAM). When the Cisco 675 is used with the Cisco 6200 DSLAM, the Cisco 675 requires bridging or Point-to-Point Protocol (PPP) configurations that vary from the typical Cisco 675 configuration.

The Cisco 675 was formerly known as the NetSpeed 204.

The Cisco Broadband Operating System (CBOS) has two interfaces that you can use to configure and operate the Cisco 675:

• Command line interface---Access this interface through the management (MGMT) port on the back of the device, using a terminal emulation program.
  
  
• Web browser interface---Use this interface if you are familiar with Web-based navigation.
  
  

Refer to the Cisco 675 Installation and Operation Manual for information regarding the use of these two interfaces.

After connecting all of the Cisco 675 cables, turn on the Cisco 675, start your terminal access program from your PC, and press the Enter key until the Cisco Broadband Operating System Welcome screen appears. When you see the Welcome screen, you can log in.

The Cisco Broadband Operating System prompt appears:

B.1 Configuring the Cisco 675 as a Bridge

Follow these steps to configure the Cisco 675 to interoperate with a Cisco 6200 using bridging. This procedure tells you how to erase the configuration currently stored in NVRAM, create a new configuration with bridging enabled, and save the new configuration.

Step 1 Erase NVRAM:

This command erases the stored configuration in NVRAM.

Step 2 Write the changes to NVRAM:

Step 3 Enter these two commands to enable RFC 1483 bridging:

Step 4 To allow bridging to take effect, write the changes again and reboot the Cisco 675:

Step 5 Enter these commands to assign VPI 0 and VCI 33 to the WAN interface:

Step 6 Turn off ATM cell scrambling:

Step 7 Set the root password:

Step 8 Set the Ethernet interface active:

Step 9 Save the new configuration:

This completes the bridging configuration.

B.2 Configuring the Cisco 675 to Use PPP

Follow these steps to configure the Cisco 675 to interoperate with the Cisco 6200 using PPP. This procedure tells you how to erase the configuration currently stored in NVRAM, create a new configuration with PPP enabled, and save the new configuration.

Step 1 Erase NVRAM:

This command erases the stored configuration in NVRAM.

Step 2 Write the changes to NVRAM:

Step 3 Using the following example as a model, configure the IP address and subnet mask for the Ethernet port. Supply your own IP address and subnet mask.

Step 4 Enter these commands to assign VPI 0 and VCI 33 to the WAN interface:

Step 5 Enter these commands to assign PPP parameters to the WAN interface. The password and authentication (login) values must match those used on the device at the other end of the PPP connection. "Cisco" is used here; substitute the value(s) appropriate for your system.

Step 6 Turn off ATM cell scrambling:

Step 7 Set the root password:

Step 8 Set the Ethernet interface active:

Step 9 Save the new configuration:

Step 10 Reboot to start using the new configuration:

This completes the PPP configuration.

B.3 Verifying the Configuration

Use the show nvram command to verify the configuration for the Cisco 675. This example shows a bridging configuration:

cbos> sh nvram

[[ ATM WAN Device Driver = Section Start ]]
ATM WAN Virtual Connection Parms = 00, 0, 33, 0
atm wan cell scrambling = disabled
[[ Spanning Tree = Section Start ]]
MAC Bridge = enabled, rfc1483
MAC Bridge Management = enabled
[[ LSL Multiplex Layer = Section Start ]]
lsl port = 00, enabled
[[ CBOS = Section Start ]]
CBOS Root Password = j_`

This example shows a PPP configuration:

cbos> sh nvram

[[ IP Routing = Section Start ]]
IP Port Address = 00, 192.168.140.255
IP Port Address Mask = 00, 255.255.255.248
[[ ATM WAN Device Driver = Section Start ]]
ATM WAN Virtual Connection Parms = 00, 0, 33, 0
atm wan cell scrambling = disabled
[[ Spanning Tree = Section Start ]]
[[ CBOS = Section Start ]]
CBOS Root Password = j_`
