Verifying the Downstream Ports
To determine if the downstream carrier is active (up), enter the show controllers cable command for the
downstream port that you just configured. For National Television Standards Committee (NTSC) 6 MHz
operations, see the following example:
Router# show controllers cable5/0/0 downstream
Cable5/0/0 Downstream is up
Frequency=96000000, Channel Width 6 MHz, 64-QAM, Symbol Rate 5.056941 Msps
FEC ITU-T J.83 Annex B, R/S Interleave I=32, J=4

Purpose
Enters enable (privileged EXEC) mode.
Enter the password.
You have entered privileged EXEC mode when the
prompt displays the pound symbol
Enters global configuration mode. You have entered
global configuration mode when the
prompt appears.
This command can be abbreviated to config t or conf
t.
Enters cable interface configuration mode.
In this example, the interface is downstream port 0
on the cable interface card installed in slot 1 of the
Cisco uBR10000 series CMTS.
Default. Activates downstream digital data from the
Cisco uBR10012 router.
Deactivates downstream digital data. This command
mutes the IF output of the cable interface card and
shuts down the interfaces.
Places the downstream port in the "admin up" state.
Returns to privileged EXEC mode.
This message is normal and does not indicate an
error.
