IP Services: Replace configuration of additional z/OS legacy device types
Description
TCP/IP DEVICE and LINK profile statements for the following legacy device types will not be
supported in a future release of IBM z/OS Communications Server:
- FDDI and Token Ring (LCS with LINKs FDDI and IBMTR)
- Token Ring (MPCIPA with LINK IPAQTR)
- Ethernet and FDDI (MPCOSA with LINKs OSAENET and OSAFDDI)
If you are currently using these profile statements, migrate to a supported interface type, such as OSA-Express QDIO or HiperSockets. For more information about using OSA-Express QDIO or HiperSockets interfaces, see Considerations for networking hardware attachment in z/OS Communications Server: IP Configuration Guide.
Table 1 provides more details about this migration action. Use this information to plan your changes to the system.
| Element or feature: | z/OS® Communications Server. |
|---|---|
| When change was introduced: | This change was announced in IBM United States Hardware Announcement 215-267 dated July 28, 2015. |
| Applies to migration from: | z/OS V1R13 and z/OS V2R1. |
| Timing: | Before installing z/OS V2R2. |
| Is the migration action required? | No, but recommended because these TCP/IP device types will not be supported in a future release of IBM z/OS Communications Server. |
| Target system hardware requirements: | None. |
| Target system software requirements: | None. |
| Other system (coexistence or fallback) requirements: | None. |
| Restrictions: | None. |
| System impacts: | None. |
| Related IBM® Health Checker for z/OS check: | ZOSMIGV2R2_NEXT_CS_LEGACYDEVICE can help you determine whether you are using any legacy device statements in your TCP/IP profile. This check is provided in z/OS V2R1 and V2R2 with TCP/IP APAR PI49962 and SNA APAR OA49071 applied. |
Steps to take
Use a supported TCP/IP interface type, such as OSA-Express QDIO or HiperSockets.
