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.
Router# show hw-module bay 1/0/0 config rf-channel 0
SPA RF Freq Mod Annex IP Address MAC Address UDP
channel port
1/0/0 0 699000000 64qam B 192.168.200.30 0011.920e.a9ff 49152
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.
Router#show hw-module bay 1/0/0 counters rf-channel 0
SPA RF channel MPEG packets tx
1/0/0 0 334815
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
