Usage Guidelines

become flooded with console printouts.
The debug commands are primarily intended for use in controlled test and troubleshooting situations
Caution
with a limited volume of traffic. In particular, avoid using the debug cable mac-scheduler command on
an interface with a significant number of CMs, because the resulting volume of debug output could
impact system performance. Cisco recommends that when you use the debug cable mac-scheduler
command, you limit its output to a particular interface or CM, using the
debug cable interface

The following examples shows admission-control debugging being turned on for a particular CM with
the MAC address of 000C.1234.5678, and the typical messages that appear if the CM cannot register
because the channel is oversubscribed.
