Chapter 5 Cisco CMTS Debugging Commands
debug cable transmit
debug cable transmit
To display debug messages for messages that the CMTS transmits on the cable interface, use the
debug
cable transmit
command in privileged EXEC mode. To stop displaying debug messages, use the
no
form of this command.
debug cable transmit
no debug cable transmit
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Command History
Examples
The following command enables debugging of messages that the CMTS transmits on the cable interface:
Router#
debug cable transmit
CMTS debug transmit debugging is on
Router#
The
debug cable transmit
command was disabled in Cisco IOS Release 12.1 T, 12.1 EC, and later
releases, although it still appears in the CLI until Cisco IOS Release 12.1(11b)EC. To monitor the
packets transmitted by the CMs, use the
debug ip packet
command instead.
Because the
debug ip packet
command produces a large volume of messages, you must use it together
with an access list to restrict the messages to a particular CM or CPE device to avoid affecting system
performance. For example, the following commands would set up an access list that monitors all traffic
being sent between the hosts with the two specified IP addresses:
router#
configure terminal
router(config)#
access-list 150 permit ip host
ip-address-1
host
ip-address-2
router(config)#
access-list 150 permit ip host
ip-address-2
host
ip-address-1
router(config)#
exit
router#
debug ip packet 150 detail
