APAR status

  • Closed as new function.

Error description

  • A new NICDISTRIBUTION option is added to a VSwitch HiperSockets
    Bridge that enables granularity to traffic from the HiperSocket.
    When activated, this new option enables the Bridge to
    distinguish and manage separately the traffic generated by
    various HiperSocket connections on the same HiperSocket CHPID
    used by the Bridge Port.
    Traffic entering and exiting the Bridge Port via an OSA link
    aggregation group will be more evenly distributed among the
    assigned OSAs in the group.
    Activation of this new option also enables the VSwitch to
    extract IPv4 and IPv6 address assignments for display in
    QUERY VSWITCH.

    ****************************************************************
    With the PTF for APAR VM66557, z/VM 7.2 adds a new
    NICDISTRIBUTION option to the VSwitch HiperSockets Bridge. When
    activated, the option enables the bridge to distinguish and
    manage separately the traffic that is generated by various
    HiperSockets connections that are on the same HiperSockets
    CHPID.  Traffic that exits the Bridge Port to an OSA link
    aggregation group is more evenly distributed across the
    entire port group.  Activation of the new option also enables
    the VSwitch to extract IPv4 and IPv6 address assignments for
    display in the QUERY VSWITCH command, monitor records, and
    DIAGNOSE x'26C'.
