Chapter2 Configuring the Cable Modem Termination System for the First Time
Configuring the Cable Interface with the Extended Setup Facility
Identifying Cable Modem Line Card Slots
On the CiscouBR7200seriesrouter, the cable interface line card is fixed and is always slot 1. To display
information about a specific cableinterface slot’s downstream channel, use the showinterfaces cable
command with the CM card’s slot number and downstream port number in the following format:
show interfaces cable slot/downstream-port [downstream]
Use the slot number and downstream port number to display information about a downstream interface.
You can abbreviate the command to shintc. The following example shows the display for upstream
channel port 0 on a CiscouBR7200seriesrouter:
Router# sh int c 5/0
To display information about a specific cableinterface slot’s upstream channel, use the
showinterfaces cable command. Include these CM card parameters:
• Slot number
• Downstream port number
• Upstream port number
Use this format:
show interfaces cable slot/downstream-port [upstream] upstream-port
Use the slot number, downstream port number, and upstream port number to display information about
an upstream interface. You can abbreviate the command to shintc.
The following example shows the display for upstream channel port 0 in cableinterface slot3 of a
CiscouBR7200seriesrouter that is turned up:
Router# sh int c3/0 upstream
