NAME

       sys_attrs_ace - ace subsystem attributes

DESCRIPTION

       This  reference	page  lists and describes attributes for the serial driver (ace) kernel subsystem, used only on the DEC 2000, AlphaServer,
       and AlphaStation family of processors. Refer to the sys_attrs(5) reference page for an  introduction  to  the  topic  of  kernel  subsystem
       attributes.

	      Number of communication ports configured for the system. The ace_cnt value is query only and cannot be changed directly by users.

	      Default value: 0

	      Minimum value: 0

	      Maximum value: 8

	      A value that turns ace debugging mode on (1) or off (0).

	      Default value: 0 (off)

	      Do not modify the default value of this attribute unless instructed to do so by support personnel.

	      The  major  number assigned to device special files /dev/tty0n (where n equals 0 to 8). The ace_major value is query only and cannot
	      be changed directly by users.

	      Default value: 35

	      Minimum value: 0

	      Maximum value: 512

	      The number of seconds that Data Carrier Detect must be done before declaring that a disconnect has occurred. Valid values are 0,	1,
	      and 2.

	      Default value: 2 (seconds)

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
