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
