For installations with 16D CAMs and 12Us, the IPv4 and IPv6 addresses are assigned on a per-MAC domain basis or
bundled across multiple MAC Domains.
IPv6 addresses cannot be assigned to the SCM ports in Release 7.x.
The CMTS can be configured to prefer IPv6 addressing of DOCSIS 3.0 CMs and DOCSIS 2.0 CMs that have support for IPv6
and still provide IPv4 services to pre-DOCSIS 3.0 CMs.
To complete this configuration:
The IPv4 and IPv6 addresses must be assigned to both the RCM interface ports as well as the RF/MAC Domains/CAMs
as described above
The back office servers used to support the DOCSIS devices as well as CPE must be configured to support both IPv4 and
IPv6 operation
Enter the following CLI commands to configure the RCM Ethernet ports:
configure interface gigabitEthernet 17/0 no shutdown
configure interface gigabitEthernet 17/0.0 ip address 10.58.0.2 255.255.255.0
configure interface gigabitEthernet 17/0.0 ipv6 enable
configure interface gigabitEthernet 17/0.0 ipv6 address FE80::/10 EUI-64 link-local
configure interface gigabitEthernet 17/0.0 ipv6 address FC00:CADA:C408:1700::2/64
configure interface gigabitEthernet 17/0.0 ip igmp
configure interface gigabitEthernet 17/0.0 ipv6 no nd ra suppress
IP Address Prefixes and Subnets
When the CMTS is configured for service, the back office systems that support the installation must also be configured and
properly setup to support the DOCSIS and non-DOCSIS devices services by the CMTS. This means that if the CMTS is
operating with both IPv4 and IPv6 devices, the time servers, provisioning servers (DHCP and tftp) and NMS devices are all
capable of operating with either IPv4 or IPv6.
Also, the DHCP servers need to be configured with the proper IPv4 and IPv6 address information and the correct DHCP
options for both legacy DOCSIS, and DOCSIS 3.0 devices.
Note: In configuring the MAC domain in the procedure above, the IP Provisioning Mode was set to IPv6 only. To support
legacy DOCSIS 2.0 CMs on the same channels in the MAC domain, IPv4 addresses must also be configured.
Configure the IPv6 on the RF:
configure interface cable-mac 1.0 ip address 10.108.0.1 255.255.224.0
