The number of the CPE that can be online is determined based on one of
the following aspects:
•
If the number of the CPE is lower than the MAX CPE value in the
DOCSIS configuration file of the cable modem, then the cable
modem max-cpe command overrides the configuration file value.
•
If number of the CPE is higher than the MAX CPE value in the
DOCSIS configuration file of the cable modem or is set as unlimited,
then the value set in the configuration file takes precedence.
If the value in the configuration file is zero and no cable modem
max-cpe is configured, then no CPE device is able to obtain an
IP address.
