Local Internet Address Selection on EE SNA/IP APPC Controller Options

on CRTCTLAPPC or CHGCTLAPPC, Link type*HPRIP; have need to be able to specify parameter LCLINTNETA in a more dynamic/transparent method. Large Environments with hundreds of LPARs; dozens of controllers and multiple IP addresses on each system; are difficult to support with hardcoded local internet addresses; where PowerHA or SRDF actions require changes to the local address. Request that LCLINTNETA be treated somewhat like RMTINTNETA and have additional capability to resolve via Host/DNS lookups.

Use Case:

Local Controller:

Remote Controller:

Helps to insure that correct (matching) interfaces are used on each end of the connection
*SYS or specific IP address should still be supported in the parameter.

    IBM does not intend to provide a new solution or make a change for *HPRIP (Enterprise Extender) on IBM i
    SNA and Enterprise Extender is considered stabilized and no new features are being considered for this component.

    A solution that pre-configured the TCP/IP interfaces and APPC controllers is recommended.
    Controllers and line descriptions for the interfaces would not be configured for On-line at IPL or to Auto start with TCP/IP.
    The startup program would be utilized to determine the appropriate configuration to start, based on the HA solution or environment of the system.
    The startup program could:
    Make a CHGCTLAPPC change for the new IP address required and VRYCFG the controller on
    Select which configuration VRYCFG needs to activate for an existing pre-configured controller with the correct IP address.

    IBM has received the requirement and is evaluating it. IBM will provide a response after evaluation is complete.

    The CAAC has reviewed this requirement and recommends that IBM view this as a “nice to have” low priority feature from the viewpoint of SMB clients. Although this may help those with a lot of LPARs who still need SNA, folks in the SMB space are not likely to need this. When possible, businesses should generally be trying to move away from this older SNA technology.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.
