Usage Guidelines
You can repeat this command for other MAC addresses. Each time you specify a different MAC address,
debugging is turned on for that particular MAC address.
If you enter two commands with the same MAC address, but with different values for the mask or
verbose keywords, the router treats both commands as the same. In this case, the latest debugging
information supersedes the previous debugging information.
Do not use this command if you have a large number of CMs on your network. The Cisco CMTS will

become flooded with console printouts.
Examples
The following example demonstrates how to enable debugging for all traffic coming from cable
interface 3/0 of CMs with the MAC address 00E0.1Exx.xxxx:
Router# debug cable interface c3/0
Router# debug cable mac-address 00E0.1E00.0000 ffff.ff00.0000
