NAME

       sys_attrs_uipc - uipc subsystem attributes

DESCRIPTION

       This  reference	page  lists  and  describes  attributes  for the AF_UNIX interprocess communication (uipc) kernel subsystem.  Refer to the
       sys_attrs(5) reference page for an introduction to the topic of kernel subsystem attributes.

	      Default value: 40960 (bytes)

	      Minimum value: 1	(Should not be less than 4096.)

	      Maximum value: UINT_MAX, or 4 billion

	      Default send buffer size, in bytes, for AF_UNIX domain datagram sockets.

	      Default value: 20480 (bytes)

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.

	      Enables (1) or disables (0) traffic control on all network interfaces on the system.

	      Default value: 0 (disabled)

	      Minimum value: 0

	      Maximum value: 1

	      Maximum number of mbufs enqueued on an interface's output queue before packets are dropped.

	      Default value: 1024 (bytes)

	      Minimum value: 1024

	      Maximum value: 65535

	      The default maximum transmission unit (MTU) for all loopback (lo) interfaces.

	      Default value: 4096 (bytes)

	      Minimum value: 68

	      Maximum value: 65535

	      Maximum number of loopback (lo) interfaces on a system. The interfaces are numbered sequentially starting with 0 (for example, lo0).

	      Default value: 1 (interface)

	      Minimum value: 1

	      Maximum value: 16581375 (or until memory is exhausted)

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

	      Default value: 1 (enabled)

	      Minimum value: 0

	      Maximum value: 1

	      The priority of the netisr protocol threads.

	      Default value: 33

	      Minimum value: 0

	      Maximum value: 63

	      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

	      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

	      Number of packet filter devices on a system.

	      Default value: 256 (devices), if PACKETFILTER option is configured in the kernel; otherwise, 0

	      Minimum value: 256

	      Maximum value: 4096

	      Number of serial line internet protocol (SLIP) lines.

	      Default value: 1 (line)

	      Minimum value: 1

	      Maximum value: 50

	      Depth of the kernel cache used by the screend facility.

	      Default value: 8 (entries)

	      Minimum value: 8

	      Maximum value: 16

	      Width of the kernel cache used by the screend facility.

	      Default value: 8 (entries)

	      Minimum value: 8

	      Maximum value: 4096

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

	      Default value: 32 (packets)

	      Minimum value: 32

	      Maximum value: 16384
