Chapter 2 Configuring the Cisco CMTS for the First Time
Using the Setup Facility for Cable Interfaces
Use the slot number and downstream port number to display information about a downstream interface.
You can abbreviate the command to sh int c. The following example shows the display for upstream
channel port 0 on a Cisco uBR7100 series router.

To display information about a specific cable interface slot’s upstream channel, use the
show interfaces 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 sh int c.
The following example shows the display for upstream channel port 0 in cable interface slot 3 of a
Cisco uBR7100 series router that is turned up:
Router# sh int c 1/0 0
Cable1/0: Upstream 0 is up
