debug cable transmit

cable transmit command in privileged EXEC mode. To stop displaying debug messages, use the no
form of this command.

12.1(11b)EC
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
