    ****************************************************************
    With the PTFs for APAR VM66219 (CP) and APAR VM66223 (DirMaint)
    applied, virtual switch support is updated to exploit the
    OSA-Express feature's Priority Queuing capabilities and
    base support is added to allow for multiple screen DirMaint
    command menus.
    
    The DirMaint NICDEF command is updated to support the addition
    of the PQUPLINKTX option to the NICDEF directory statement.
    
    The following new option is added:
              PQUPLINKTX    LOW
                            NORMAL
                            HIGH
    

Problem conclusion

Temporary fix

Comments

  • For information on the syntax and the values for the new
    PQUPLINKTX option added to the DirMaint NICDEF command see:
    
    SC24-6188-06 z/VM: Directory Maintenance Facility Commands
    Reference.
    
    The new option includes:
    
      PQUPLINKTX LOW|NORMAL|HIGH
    
      For a virtual switch with priority queueing enabled,
      PQUPLINKTX sets the priority for all packets sent from a
      NIC's network connection to an external network. If
      PQUPLINKTX is not specified, all outbound traffic to the
      external network is sent at a NORMAL priority on the virtual
      switch uplink port. If PQUPLINKTX is configured for a virtual
      switch without priority queuing enabled, the setting is saved
      and used if priority queuing is enabled at a later time.
    
      LOW
    
      specifies that the outbound traffic to the external network
      is set at a low priority. This traffic uses the low priority
      queue, which is serviced less frequently than the normal or
      high priority queues.
    
      NORMAL
    
      specifies that the outbound traffic to the external network
      is set at a normal priority. This traffic uses the normal
      priority queue, which is serviced less frequently than the
      high priority queue but more frequently than the low priority
      queue.
    
      HIGH
    
      specifies that the outbound traffic to the external network
      is set at a high priority. This traffic uses the high
      priority queue, which is serviced more frequently than the
      normal or low priority queues.
