Steps for enabling IPv6 on a stack for access to the intranode management network

The intranode management network (INMN) is an IPv6 network that provides connectivity between network management applications within a zEnterprise® node

Perform the following steps to enable IPv6 on a stack so that the stack can access the INMN:

1. Use the NETSTAT CONFIG command to view the current TCP/IP configuration. If an IPv6 Configuration Table section is reported, no further actions are required.
2. Test and migrate any scripts that you use to format Netstat output in long format. After you enable a z/OS® TCP/IP stack for IPv6, Netstat output for the stack is available in the long format only. While you are still using IPv4 for your data networks, you can test the Netstat reports in the long format using one of the following methods:
   • Use the FORMAT/-M LONG option on the Netstat command.
   • Specify the FORMAT LONG parameter on the IPCONFIG statement in your TCP/IP profile.

   For more information about the Netstat command, see z/OS Communications Server: IP System Administrator's Commands. For more information about the IPCONFIG statement, see z/OS Communications Server: IP Configuration Reference.

3. Update the BPXPRMxx parmlib member to include an additional NETWORK statement for IPv6. Find the existing NETWORK DOMAINNAME(AF_INET) statement, note the MAXSOCKETS and TYPE values that are specified, and add the following statement after the existing statement using those same values:

   NETWORK DOMAINNAME(AF_INET6)
   DOMAINNUMBER(19)
   MAXSOCKETS(number)
   TYPE(file_system_type)
