sys_attrs_net(5)
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_depth
The depth of each hash bucket chain for each hash bucket specified by
arptab_nb.
Default value: 16 (entries)
Minimum value: 16
Maximum value: 256
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: 1024
ether_cl_scheduler
Enables (1) or disables (0) traffic control on all network interfaces
on the system.
Default value: 0 (disabled)
Minimum value: 0
Maximum value: 1
ifqmaxlen
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
lo_def_ip_mtu
The default maximum transmission unit (MTU) for all loopback (lo)
interfaces.
Default value: 4096 (bytes)
Minimum value: 68
Maximum value: 65535
lodevs
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)
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: 1 (enabled)
Minimum value: 0
Maximum value: 1
netisrpriority
The priority of the netisr protocol threads.
Default value: 33
Minimum value: 0
Maximum value: 63
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: 16
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
