sys_attrs_net - net subsystem attributes
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.
Number of seconds until the system deletes a complete
ARP entry from the ARP cache.
Default value: 1200 (seconds)
Minimum value: 1
Maximum value: 32767
Number of seconds until the system deletes an
incomplete ARP entry from the ARP cache.
Default value: 180 (seconds)
Minimum value: 1
Maximum value: 32767
Number of seconds until the system refreshes a complete
ARP entry in the ARP cache.
Default value: 120 (seconds)
Minimum value: 1
Maximum value: 32767
A value that specifies whether the initial ARP
refresh packet is unicast (1) or broadcast (0). It
is best to leave this parameter at the default setting,
because it minimizes the amount of broadcast
traffic on the network. However, some vendors' network
switches will occasionally drop unicast ARP
packets; in this case, the behavior should be
changed to broadcast (0).
Default value: 1 (unicast)
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 protocol 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
Enables (1) or disables (0) the looping back of
output packets written by the packet filter.
Default value: 1 (enabled)
Minimum value: 0
Maximum value: 1
Enables (1) or disables (0) the supplying of a
source Media Access Control (MAC) address by the
packet filter on all outgoing packets.
Default value: 1 (enabled)
Minimum value: 0
Maximum value: 1
Specifies the maximum speed for TCP traffic for any
route created on the system.
Default value: 0 (bits per 200 milliseconds)
Minimum value: 0
Maximum value: UINT_MAX, or 4 billion
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
