IPv6 Configuration (Optional)
This section assigns the IPv4 subnets and IPv6 prefixes that will be configured in the C4 CMTS. In Release 7.x, the setup of
IP subnets and prefixes has been augmented with support for IPv6. This allows the operator to run either IPv4 or IPv6 or
both protocols in a chassis.
Release 7.x enhancements and changes to the configuration include:
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 8.x.
The C4 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 2001:db8: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 C4 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 C4 CMTS. This means that if the C4
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.
