Chapter 2 Configuring the Cable Modem Termination System for the First Time
Configuring the Cisco uBR7200 Series Manually Using Configuration Mode
Step 4 Enter the configure terminal command (conf t)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.
Step 5 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)#
Step 6 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.
Step 7 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
Step 8 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.
Step 9 Repeat Step 8 for each upstream port on the cable interface line card.
Step 10 Activate the upstream port:
Router(config-int)# no cable upstream port shutdown
Step 11 Repeat Step 10 to activate each port used on your cable interface line card.
Step 12 Exit to return to the configuration mode:
Router(config-if)# exit
Router(config)#
Step 13 Enter the next interface to configure, following Step 6 through Step 12, or type exit to return to enable
mode.
Router(config)# exit
Router#
%SYS-5-CONFIG_I: Configured from console by console#
Step 14 Save the configuration to NVRAM:
Router# copy running-config startup-config
