OSA Direct SNMP subagent support requires a server with the OSA-Express feature running in QDIO mode (OSD) or non-QDIO mode (OSE). It is available on all servers supported by z/OS. For information about the level of each server that is required for this support, see zEnterprise System and System z10 OSA-Express Customer's Guide and Reference.

For additional information about OSA, see the following publication:
  • OSA-Express: zEnterprise System and System z10 OSA-Express Customer's Guide and Reference

IBM 37xx family of communication controllers for X.25, Systems Network Architecture, and IP over Channel Data Link Control:
  • IBM 3745 Communication Controller for:
    • X.25
    • Ethernet
    • Token Ring
    • Frame Relay
  • A microcode engineering change (EC) is required for the IP Dynamics (with Ethernet) capabilities:
    • C38006 for models 130, 150, 160, 170, and 17A
    • C37967 for models 210, 310, 410, and 610
    • C39888 for models 21A, 31A 41A, and 61A
  • IBM 3746 or 3746–900 Communication Controller for:
    • X.25
    • ATM
    • Token Ring
    • Frame Relay
  • A microcode engineering change (EC) is required for the IP-over-Channel (CDLC) for the 3746.
    The 3746-900 requires microcode EC number D22510 at microcode change level ECA 142 for communication across an ESCON channel. The microcode level is shipped automatically with new 3746-900s. For installed machines running an earlier level of microcode, microcode ECA 142 can be ordered by the service representative.
  • Standard System/370 I/O Channel Interface Cable

HYPERchannel A220 Processor Adapter 42990007:
  • HYPERchannel Series A devices
  • HYPERchannel Series DX devices, provided they function as Series A devices (For additional information, refer to the appropriate Network Systems Corporation documentation.)
  • Standard System/370 I/O Interface cable

The ATTENTION+BUSY and unit check conditions are normally handled in the background and can affect performance without any visible evidence. The recommendations on HYPERchannel A222 and A223 Mode Switch Settings follow:
  • The Disable Attentions setting on the HYPERchannel box eliminates the ATTENTION+BUSY status in response to read commands. This setting reduces overhead.
  • The Enable Command Retry setting reduces the number of unit checks needed because of a trunk connection. This setting improves performance because it eliminates the need to perform sense operations and retry commands.

Miscellaneous IP hardware requirements
IPv6 support requires any of the following:
  • Any OSA-Express, OSA-Express2, or OSA-Express3 feature defined for QDIO mode (OSD)
  • Multipath channel Point-to-Point (MPCPTP) Data Link Control (DLC), which may carry IPv6 traffic over ESCON/FICON, XCF links, and IUTSAMEH

IP over native ATM requires:
  • v OSA-2 adapter
  • v ATM external private or public equipment, for example, IBM 8260 NWays Multiprotocol Intelligent Switching Hub

Use of HiperSockets IPv6 support requires at a minimum a zEnterprise, System
z10, or a System z9 server.

Use of HiperSockets multiple write facility requires a zEnterprise server or a
System z10 server.
SNAFor communication with remote resources, one or more of the following products, or their equivalent, is required:
  • Channel-to-channel adapter
  • FICON channel-to-channel adapter
  • IBM 2216 NWays Multiaccess Connector
  • IBM 3088 Multisystem Channel Communication Unit
  • IBM 3172 Nways® Interconnect Controller
  • IBM 3174 Establishment Controller

  • IBM 3746 Nways Multiprotocol Controller
  • IBM Cross-System Coupling Facility (XCF)
  • IBM Enterprise System Connection (ESCON) channel
  • IBM Open Systems Adapter-Express
  • IBM Open Systems Adapter

APPN over native ATM requires:
  • OSA-2 adapter
  • ATM external private or public equipment, for example, IBM 8260 NWays Multiprotocol Intelligent Switching Hub

VTAM cryptographic enhancements, when used with the extended recovery facility (XRF) and Transaction Security System (TSS) family of products (4755), require 4755 Model 23 and later.

SNA triple DES (TDES) session level encryption requires a Cryptographic Coprocessor on the server.
