VM66557: VSWITCH BRIDGEPORT ENHANCEMENTS

Obtain the fix for this APAR.

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'.
