SMTCONFIG(1M)SMTCONFIG(1M)NAMEsmtconfig - configure or display FDDI interface parameters
SYNOPSIS
/usr/etc/smtconfig interface [address_family] [address] [parameters]
/usr/etc/smtconfig interface
DESCRIPTIONsmtconfig is used to configure FDDI network interfaces. smtconfig is
invoked at boot time from /etc/init.d/network to define the network
address of each FDDI interface present on a machine. You may also use it
once the system is up to redefine an interface's address or other
operating parameters.
The interface parameter is a string of the form ``name unit'', for
example, ``ipg0''. Use smtstat(1) or netstat(1) to display the names of
FDDI interfaces on the machine.
Since an interface may receive transmissions in differing protocols, each
of which may require separate naming schemes, it is necessary to specify
the address_family, which may change the interpretation of the remaining
parameters. Currently, just the ``inet'' address family is supported.
For the Internet family, the address is either an Internet address
expressed in the Internet standard ``dot notation'' (see inet(3N)), or a
host name present in the hosts(4) file, /etc/hosts. (Other hosts
databases, such as named and NIS, are ignored.)
Only the superuser may modify the configuration of a network interface.
The following parameters may be set with smtconfig:
up Mark an interface ``up''. This parameter may be used to
enable an interface after an ``smtconfig down.'' It
happens automatically when setting the first address on an
interface. If the interface was reset when previously
marked down, the hardware will be re-initialized.
down Mark an interface ``down''. When an interface is marked
``down'', the system will not attempt to transmit messages
through that interface. If possible, the interface will be
reset to disable reception as well. This action does not
automatically disable routes using the interface.
arp Enable the use of the Address Resolution Protocol in
mapping between network level addresses and link level
addresses (default). This is currently implemented for
mapping between Internet addresses and FDDI MAC addresses.
-arp Disable the use of the Address Resolution Protocol.

metric n Set the routing metric of the interface to n, default 0.
The routing metric is used by the routing protocol
(routed(1m)). Higher metrics have the effect of making a
route less favorable; metrics are counted as addition hops
to the destination network or host.
netmask mask Specify how much of the address to reserve for subdividing
networks into subnetworks. The mask includes the network
part of the local address and the subnet part, which is
taken from the host field of the address. The mask can be
specified as a single hexadecimal number with a leading
0x, with a dot-notation Internet address, or with a
pseudo-network name listed in the network table
networks(4). The mask contains 1s for the bit positions
in the 32-bit address which are to be used for the network
and subnet parts, and 0s for the host part. The mask
should contain at least the standard network portion, and
the subnet field should be contiguous with the network
portion.
broadcast Specify the address to use to represent broadcasts to the
network. The default broadcast address is the address
with a host part of all 1s.
debug Enable driver-dependent debugging code; usually, this
turns on extra console error logging.
-debug Disable driver-dependent debugging code.
primary Select an interface as the primary network interface for
this host.
smtconfig displays the current configuration for a network interface when
no optional parameters are supplied. If a protocol family is specified,
smtconfig will report only the details specific to that protocol family.
DIAGNOSTICS
Messages that indicate the specified interface does not exist, the
requested address is unknown, or the user is not privileged if trying to
alter an interface's configuration.
