debug cable receive
To display debug messages for messages received on the upstream from a CM, use the
debug cable
receive
command in privileged EXEC mode. To stop displaying debug messages, use the
no
form of this
command.
debug cable receive
no debug cable receive
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Command History
Examples
The following command enables debugging of upstream messages:
router#
debug cable receive
CMTS debug Rx debugging is on
The
debug cable receive
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 received from 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
