Feature Interaction
PacketCable services have been designed to work with all other features of the C4/c CMTS including in-band management,
DHCP relay agent, and redundancy. In fact, for Control Complex Redundancy to work properly, the interface (typically a
logical loopback interface) used for connections to the Call Management Server, Policy Server, Record Keeping Server, and
Delivery Function needs to be configured with the In-band Management feature to have RCM access. This way, if a CCR
failover occurs, the links to the failed RCM are automatically restarted on the redundant RCM. CAM redundancy works
with PacketCable through the same sparing groups that are set up for data services. The DHCP relay agent is typically
configured to perform policy-based agent functionality so that the MTAs (which behave as CPE hosts) are provided with an
IP address space that is separate from the cable modem address space.
Note: Control Complex Redundancy does not apply to the C4c CMTS.
PC1.x and PCMM are designed to coexist on the C4/c CMTS. Either one or both can be enabled. Either can be disabled
without impairing the function of the other.
