NAME
  sys_attrs_net - net subsystem attributes

DESCRIPTION
  This reference page lists and describes attributes for the Network (net)
  kernel subsystem. Refer to the sys_attrs(5) reference page for an
  introduction to the topic of kernel subsystem attributes.



  arptab_nb
      Number of hash buckets in the address resolution protocol (ARP)  table.
      For optimal hashing, the number should be a prime number.

      Default value: 37 (buckets)

      Minimum value: 11

      Maximum value: 257



  netisrfair
      Enables (1) or disables (0) fair allocation of netisr protocol threads.
      When enabled (1), only 1 netisr thread runs for each protocol queue.

      Default value: 0 (disabled)

      Minimum value: 0

      Maximum value: 1



  netisrthreads
      Number of network threads configured in a system.

      Default value: n (Based on the number  of CPUs in a system.  For a
      system with one processor,  the value is 1.  For a multiprocessing
      system, the value is 1 plus the  number of processors.)

      Minimum value: 1

      Maximum value: 50



  netisrwakeupthreshold
      Number of packets (packet threshold) above which another netisr thread
      is started.

      Default value: 1 (packet)

      Minimum value: 1

      Maximum value: INT_MAX, or 2 billion



  nslip
      Number of serial line internet protocol (SLIP) lines.

      Default value: 1 (line)

      Minimum value: 1

      Maximum value: 50



  screen_cachedepth
      Depth of the kernel cache used by the screend facility.

      Default value: 8 (entries)

      Minimum value: 8

      Maximum value: 4096



  screen_cachewidth
      Width of the kernel cache used by the screend facility.

      Default value: 8 (entries)

      Minimum value: 8

      Maximum value: 4096



  screen_maxpend
      Maximum number of packets pending allowed in the screend facility
      queue.

      Default value: 32 (packets)

      Minimum value: 32

      Maximum value: 16384
