Chapter2 Configuring the Cable Modem Termination System for the First Time
Configuring the Cisco uBR7200 Series Manually Using Configuration Mode
Step4 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.
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.
Step9 Repeat Step 8 for each upstream port on the cable interface line card.
Step10 Activate the upstream port:
Router(config-int)# no cable upstream port shutdown
Step11 Repeat Step 10 to activate each port used on your cable interface line card.
Step12 Exit to return to the configuration mode:
Router(config-if)# exit
Router(config)#
Step13 Enter the next interface to configure, following Step 6 through Step 12, or type exit to return to enable
mode.
Router(config)# exit
