Question
What do I have to do to enable my TCP/IP stack for IPv6?
Answer
z/OS Communications Server can be run as an IPv4-only stack or as a dual-mode stack (IPv4 and IPv6). The BPXPRMxx parmlib member determines which mode is used.
To configure your stack as a dual-mode stack (IPv4 and IPv6), you can choose either of the following configurations:
INET IPv4/IPv6 dual-mode stack
CINET IPv4/IPv6 dual-mode stack
INET IPv4/IPv6 dual-mode stack BPXPRMxx sample definition
Dual-mode (IPv4/IPv6) stack support is defined by using two NETWORK statements (one for AF_INET and one for AF_INET6) in the BPXPRMxx parmlib member.
CINET IPv4/IPv6 dual-mode stack BPXPRMxx sample definition
Dual-mode (IPv4/IPv6) stack support is defined by using two NETWORK statements ((one for AF_INET and one for AF_INET6) in the BPXPRMxx member. Each TCP/IP stack is defined in the BPXPRMxx parmlib member by using a SUBFILESYSTYPE statement.
If you do not configure your stack for IPv6, but you specify IPCONFIG6 in the stack's PROFILE, the following error message is generated, and TCP/IP startup processing continues:
EZZ0695I IPCONFIG6 NOT VALID - IPV6 SUPPORT IS NOT ENABLED
