What’s new in DOCSIS 3.0 provisioning
• IPv6 for CM management
• IPv6 provisioning
• Dual-stack management
• Alternative Provisioning Mode (APM)
•Extensions to DHCP
• Improved security
• IPv6 service to the customer premises (bridging
CM); Home gateway to customer network

Context for Provisioning
• Downstream channel acquisition
• Upstream channel initialization
•CMTS aware of downstream/upstream pair
• Provisional MAC initialization

• The last 64 bits of unicast IPv6 addresses
• Interface identifier based on:
