Support considerations

Description: z/OS® Communications Server includes the following enhancement for support considerations.

  • Support considerations in V2R3 - Support for the following functions is discontinued.
    • Several TCP/IP device drivers:
      • 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)
      You must migrate from these device types to later types, such as OSA-Express QDIO and HiperSockets.
      Note: Support for SNA device drivers is not affected.
    • The Trivial File Transfer Protocol function. Anyone using this function should use an alternate file transfer protocol.
    • Simple Mail Transport Protocol Network Job Entry (SMTPD NJE) mail transport
    • Sendmail mail transport
    • Several migration health checks:
      • ZOSMIGV2R2_NEXT_CS_LEGACYDEVICE
      • ZOSMIGV2R2_NEXT_CS_TFTP
      • CSAPP_SMTPD_MAIL_RELAY
      • ZOSMIGV2R2_NEXT_CS_SENDMAILCLIEN
      • ZOSMIGV2R2_NEXT_CS_SENDMAILDAEMN
      • ZOSMIGV2R2_NEXT_CS_SENDMAILMSA
      • ZOSMIGV2R2_NEXT_CS_SENDMAILMTA
      • ZOSMIGV2R2_NEXT_CS_SMTPDDAEMON
      • ZOSMIGV2R2_NEXT_CS_SMTPDMTA

    When change was introduced: z/OS V2R3

  • Support considerations in V2R2 - Support for the following functions is discontinued.
    • Several TCP/IP device drivers
      • Asynchronous Transfer Mode (ATM)
      • Common Link Access To Workstation (CLAW)
      • HYPERChannel
      • Channel Data Link Control (CDLC)
      • SNALINK (both LU0 and LU6.2)
      • X.25
      Note: Support for SNA device drivers is not affected.
    • GATEWAY profile statement

    When change was introduced: z/OS V2R2
