dlpi_max_ub_promisc(5)					dlpi_max_ub_promisc(5)

       dlpi_max_ub_promisc  -  maximum	number	of unbound promiscuous streams
       allowed on a LAN interface

   Allowed values
   Recommended values
       The tunable is used to dynamically increase  or	decrease  the  maximum
       number  of  unbound  promiscuous	 streams  that	can be opened on a LAN

       Enabling multiple unbound promiscuous streams may cause CPU utilization
       to  increase  up	 to three times as compared to CPU utilization with no
       unbound promiscuous streams.  Increasing the value of this tunable does
       not by itself degrade networking or kernel performance.

   Who Is Expected to Change This Tunable?
       Privileged user.

   Restrictions on Changing
       Changes to this tunable take effect immediately.	 When value is reduced
       from a higher value to a lower value, the existing unbound  promiscuous
       streams	will  not be stopped to accommodate the change.	 However, this
       tunable will limit the new unbound streams created on the interface.

   When Should the Value of This Tunable Be Raised?
       This tunable should be raised when the number  of  unbound  promiscuous
       applications needs to be more than the default value.

   What Are the Side Effects of Raising the Value?
       Side effect may be an increase in CPU utilization.

       All HP-UX kernel tunable parameters are release specific.  This parame‐
       ter may be removed or have its meaning changed in  future  releases  of

       Installation of optional kernel software, from HP or other vendors, may
       cause changes to tunable parameter values.   After  installation,  some
       tunable	parameters may no longer be at the default or recommended val‐
       ues.  For information about the effects of installation on tunable val‐
       ues, consult the documentation for the kernel software being installed.
