How do I enable a TCPIP stack for IPv6?

Question & Answer


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
