A channel-bonded wideband channel is associated with at least two RF channels depending on the
wideband channel’s configuration. The
cable rf-channel
command associates an RF channel with a
wideband channel. The bandwidth percent (BW %) of each RF channel used for the wideband channel
is 100 percent by default but is configurable with the
cable rf-channel
command.
Troubleshooting Wideband Cable Modems
This section describes troubleshooting techniques for wideband cable modems. It includes the following
sections:
•
Pinging a Wideband Cable Modem, page 5-19
•
Verifying That a Wideband-Capable Cable Modem is Registered as a Wideband Modem, page 5-20
•
Verifying Other Information for Wideband Cable Modems, page 5-21
Pinging a Wideband Cable Modem
To determine whether a wideband cable modem or any DOCSIS cable CPE device is reachable from the
CMTS at the DOCSIS MAC layer, use the
ping docsis
command with either a MAC address or IP
address. For example:
Router#
ping docsis 1.11.0.5
Queueing 5 MAC-layer station maintenance intervals, timeout is 25 msec:
!!!!!
Success rate is 100 percent (5/5)
