Monitoring Wideband Components Chapter 5 Monitoring and Troubleshooting Wideband Components Monitoring RF Channels The following command is useful for monitoring RF channels on a Wideband SPA: show hw-module bay. show hw-module bay To display information about RF channels on a Wideband SPA, use the show hw-module bay command with the rf-channel keyword. You also have to specify one of the following keywords indicating the particular type of information you want to show: • config-Displays RF channel configuration information. • counters-Displays RF channel statistics. • mapping-Displays the mapping of RF channels to wideband channels. To display configuration information for an RF channel, use show hw-module bay with the config and rf-channel keywords. If you specify an RF channel number after rf-channel, output is for that channel only. For example, the following output is for RF channel 0 on the Wideband SPA located in slot/subslot/bay 1/0/0.

Monitoring RF Channels
The following command is useful for monitoring RF channels on a Wideband SPA:
show hw-module
bay
.
show hw-module bay
To display information about RF channels on a Wideband SPA, use the
show hw-module bay
command
with the
rf-channel
keyword. You also have to specify one of the following keywords indicating the
particular type of information you want to show:
•
config—
Displays RF channel configuration information.
•
counters—
Displays RF channel statistics.
•
mapping—
Displays the mapping of RF channels to wideband channels.
To display configuration information for an RF channel, use
show hw-module bay
with the
config
and
rf-channel
keywords. If you specify an RF channel number after
rf-channel
, output is for that channel
only. For example, the following output is for RF channel 0 on the Wideband SPA located in
slot/subslot/bay 1/0/0.

In the preceding output, these fields provide information on the edge QAM device that is associated with
the RF channel:
•
IP Address—The IP address of the edge QAM device.
•
MAC address—The MAC address of the next-hop or edge QAM device.
•
UDP port—The UDP port number for the edge QAM that will be used for this RF channel.
To display MPEG packets transmitted for an RF channel, use
show hw-module bay
with the
counters
and
rf-channel
keywords.

Monitoring Wideband Cable Modems
The following commands are useful for monitoring wideband cable modem:
•
show cable modem wideband
•
show cable modem summary
Many other
show cable
commands display information on wideband cable modems if a wideband cable
modem or a cable interface used for a wideband cable modem is specified in the command’s arguments.
Some examples of these commands are:
•
show cable modem vendor
•
show cable modem cnr
