Chapter2 Configuring the Cable Modem Termination System for the First Time
Configuring the Cisco uBR7200 Series Using the Setup Facility
Complete these steps to activate upstream interfaces:
Step1 After the Setup facility has initially configured noncable interfaces on the CiscouBR7200seriesrouter,
enter the enable command and your password (privileged EXEC).
Step2 Enter the configure terminal command to get into global configuration mode.
Step3 In global configuration mode, configure modulation profiles and spectrum groups for your
CiscouBR7200seriesrouter using the cable modulation-profile and cable spectrum-group
commands.
Step4 In cable interface configuration mode, configure various characteristics for the interface in question,
using the cable upstream commands.
Note Refer to Chapter2, “Configuring the Cable Modem Termination System for the First Time,” for further
information.
Configuring Interfaces with the Setup Facility
Follow the procedure in this section to configure WAN or LAN interfaces. To configure interface
parameters, have your interface network addresses and subnet mask information ready.
Configuring Ethernet Interfaces
Step1 In the following example, the system is being configured for an Ethernet LAN using IP. Respond to the
prompts as follows, using your own addresses and mask at the setup prompts:
Configuring interface parameters:
Configuring interface Ethernet0/0:
Is this interface in use? [no]: yes
Configure IP on this interface? [no]: yes
IP address for this interface: 1.1.1.10
Number of bits in subnet field [0]:
Class A network is 1.0.0.0, 0 subnet bits; mask is 255.0.0.0
Step2 Do not enable Internetwork Package Exchange (IPX) on this interface; IPX is not supported on the Cisco
uBR7200 series universal broadband router:
Configure IPX on this interface? [no]: no
Step3 If additional Ethernet interfaces are available in your system, enter their configurations when you are
prompted.
Step4 Save the configuration to NVRAM:
Router# copy running-config startup-config
Note You must always manually save the configuration settings to NVRAM whenever they are modified.
