Enterprise Extender IPv6 address configuration

z/OS® V2R1 Communications Server enhances your ability to configure your IPv6 EE connections by allowing you to specify an IPv6 address instead of a hostname. You can specify IPADDR as any of the following items:

A VTAM® start option
A parameter on the GROUP statement in an XCA major node
A parameter on the PATH statement in a switched major node

Requirements:

If you are enabling the new IPv6 IPADDR on a GROUP statement in an XCA major node that defines a connection network on z/OS V2R1 Communications Server, you must apply the PTFs for APAR OA38234 on previous releases of z/OS Communications Server. The PTFs for APAR OA38234 are required to allow a previous release to activate or select an HPR pipe over EE to the z/OS V2R1 Communications Server host using an IPv6 IPADDR for a connection network.

Table 1 indicates the PTFs for APAR OA38234 that are required to make the supported releases compatible with V2R1.

Table 1. PTFs for APAR OA38234
z/OS Communications Server version	PTF for APAR OA38234
V1R12	UA65031
V1R13	UA65032

For distributed Communications Servers or other HPR products to use an HPR pipe over EE to the z/OS V2R1 Communications Server host using an IPv6 IPADDR for a connection network , those products must implement the logic that is needed to support receiving an IPv6 address in the RSCV for an HPR pipe using a connection network. If the destination HPR platform does not support receiving an IPv6 address in the RSCV, the HPR pipe activation or selection fails.

The IPv6 address in the RSCV support is made available in the following product:

Communications Server for Data Center Deployment v7

Configuring an IPv6 address for your EE connections

To configure an IPv6 address for your EE connections, perform the appropriate tasks in Table 2.

Table 2. Enterprise Extender IPv6 address configuration
Task	Reference
Specify an IPv6 address for the IPADDR start option or for the IPADDR operand on the XCA GROUP statement or the Switched EE PATH statement.	See the following topics in z/OS Communications Server: SNA Resource Definition Reference: IPADDR start option XCA major node operand IPADDR Switched major node operand IPADDR or MODIFY VTAMOPTS command in z/OS Communications Server: SNA Operation.
Display the IPADDR start option. Issue the DISPLAY NET,VTAMOPTS,OPTION=IPADDR or the DISPLAY NET,VTAMOPTS command.	DISPLAY VTAMOPTS command in z/OS Communications Server: SNA Operation
Display the IPADDR on the XCA GROUP. Issue the DISPLAY NET,ID=group_name command.	DISPLAY ID command in z/OS Communications Server: SNA Operation
Display the IPADDR on the Switched EE PATH. Issue the DISPLAY NET,PATHS,ID=pu_name command.	DISPLAY PATHS command in z/OS Communications Server: SNA Operation
