Configuring the CiscouBR10012Router Manually Using Configuration Mode
You can configure the CiscouBR10012router manually if you prefer not to use the Setup facility or
AutoInstall. Complete the following steps:
Step1 Connect a console terminal to the console port on the I/O controller.
Step2 When asked if you want to enter the initial dialog, answer no to go into the normal operating mode of
the router:
Would you like to enter the initial dialog? [yes]: no
Step3 After a few seconds, the user EXEC prompt (Router>) appears. Type enable to enter enable mode
(configuration changes can be made only in enable mode):
Router> enable
The prompt changes to the enable mode (also called privileged EXEC) prompt:
Router#
Step4 Enter the configure terminal command at the enable prompt to enter configuration mode from the
terminal:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Tip To see a list of the configuration commands available to you, enter ? at the prompt or type help while
in configuration mode.
Step5 At the Router(config)# prompt, enter the interface type slot/port command to enter the interface
configuration mode:
Router(config)# interface cable slot/port
Router(config-if)#
Step6 Set the downstream center frequency to reflect the digital carrier frequency of the downstream RF carrier
(the channel) for the downstream port:
Router(config-int)# cable downstream frequency down-freq-hz
Note This command has no effect on the external upconverter. It is informational only.
Step7 Activate the downstream port on the cable interface line card to support digital data transmission over
the hybrid fiber-coaxial network:
Router(config-int)# no shutdown
Step8 Enter the fixed center frequency in Hz for your downstream RF carrier and the port number:
Router(config-int)# cable upstream port frequency up-freq-hz
Note Be sure not to select an upstream frequency that interferes with that used for any other
upstream application in your cable plant.
