The following example displays show interface wideband-cable command output for wideband
channel 0 on the Wideband SPA in slot/subslot/bay 1/0/0.
Router# show interface wideband-cable 1/0/0:0
Wideband-Cable1/0/0:0 is up, line protocol is up
Hardware is Wideband CMTS Cable interface, address is 0012.001a.8896 (bia

30 second input rate 0 bits/sec, 0 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
Hardware Status and Line Protocol Status for a Wideband-Channel Cable Interface
When a wideband-channel cable interface is specified in show interface wideband-cable or another
Cisco IOS command that displays hardware status and line protocol status for a cable interface, the
following applies:
•
•
If the line protocol for a wideband-channel cable interface is up, all wideband-channel configuration
information needed to successfully send data is present. However, additional configuration information
may be needed to complete the Wideband SPA configuration process. For information on Wideband SPA
configuration procedures, see the Cisco uBR10012 Universal Broadband Router SIP and SPA Software
Configuration Guide.
show hw-module bay
To display additional information about a wideband channel, use the show hw-module bay command
with the wideband-channel keyword. You also have to specify one of the following keywords indicating
the particular type of information you want to show:
OL-10705-02
reliability 255/255, txload 1/255, rxload 1/255
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
17470 packets output, 1810488 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out
The hardware status for a wideband-channel cable interface will be up if the Wideband SPA is
installed in the Wideband SIP and both are powered on.
The line protocol for a wideband-channel cable interface will be up if the wideband channel is
associated with at least one RF channel and the following parameters have been set for the RF
channel:
RF channel frequency
–
MAC address of the edge QAM device or next-hop router
–
–
IP address of the edge QAM device
–
UDP port number for the QAM that is used for the RF channel
