the Cisco CMTS routers, see
"Cisco CMTS Show Commands."
The debug commands are primarily intended for use in controlled test and troubleshooting situations
Caution
with a limited volume of traffic. You should use caution when enabling debug messages because sending
these messages to the console consumes system resources. Cisco recommends that when you use the
debug cable commands, you limit their output to a particular interface or CM, using the
interface
Tip
When using the debug commands, you might occasionally see messages similar to the following:
%LCLOG-3-INVSTATE: LC logger in bad state (LC=5/0,state=WAITING FOR TEXT,msg=MSG
START)-Traceback
These messages indicate that the processor has displayed the first part of one message and was waiting
for the information needed for the second half of the message when a new message was generated. The
debug routines thus print the new message without waiting for the information from the previous
message. These messages are informational only and can be ignored.
