.Sh NAME
|

.Nm wlconfig
|

.Nd read/write wavelan config parameters
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Ar ifname
|
|
.Op Ar param value ...
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command can be used to read and set parameters for the NCR/AT&T Wavelan
|
|
radio LAN card. Various parameters stored in the nonvolatile Parameter
|
|
Storage Area (PSA) on the card can be modified with this program, which
|
|
obviates the need for the DOS-based
|
|
.Nm instconf.exe
|
|
program. It can also be used to interrogate the optional signal
|
|
strength cache which may have been compiled into the driver.
|
|
.Pp
|
|
The
|
|
.Ar ifname
|
|
parameter specifies the wavelan interface name (eg.
|
|
.Pa wl0
|
|
). If no other arguments are supplied, the current contents of the PSA
|
|
are interpreted and displayed.
|
|
.Pp
|
|
The
|
|
.Ar param
|
|
and
|
|
.Ar value
|
|
arguments can be used to change the value of several parameters.
|
|
Any number of
|
|
.Ar param value
|
|
pairs may be supplied.
|
|
.Bl -tag -width 15n -compat -offset indent
|
|
.It Va param
|
|
.Va value
|
|
.It irq
|
|
IRQ value (used at next reset), may be one of 3,4,5,6,10,11,12,15.
|
|
.It mac
|
|
Local MAC value (ethernet address).
|
|
.It macsel
|
|
.Sq soft
|
|
(as set by the
|
|
.Sq mac
|
|
parameter) or
|
|
.Sq default
|
|
(as set at the factory).
|
|
.It nwid
|
|
The NWID is a 2-byte parameter passed to the card's radio modem.
|
|
NWIDs allow multiple logically discrete networks to operate
|
|
independantly whilse occupying the same airspace.
|
|
Packets with a different NWID are simply ignored by the modem.
|
|
In the hardware, NWIDs are stored long-term in non-volative memory
|
|
(called the PSA or programmable storage area), and are loaded by
|
|
software into the radio modem when the driver is
|
|
initialized. This sets the default NWID loaded at startup.
|
|
.It currnwid
|
|
This sets the current operating NWID (but does not save it to the
|
|
PSA).
|
|
.It cache
|
|
The driver may maintain a per interface fixed size cache of signal strength,
|
|
silence, and quality levels, which are indexed by sender MAC addresses.
|
|
Input packets are stored in the cache, and when received, the values
|
|
stored in the radio modem are interrogated and stored.
|
|
There are also two sysctl values (iponly and multicast only) which
|
|
can be used for filtering out some input packets. By default, the
|
|
cache mechanism stores only non-unicast IP packets, but this can
|
|
be changed with
|
|
.Xr sysctl 8 .
|
|
Each non-filtered
|
|
input packet causes a cache update, hence one can monitor
|
|
the antennae signal strength to a remote system.
|
|
There are three commands that can be given as values:
|
|
.Sq raw ,
|
|
which prints out the raw signal strength data as found in the radio
|
|
modem hardware value,
|
|
.Sq scale ,
|
|
which scales the raw hardware values to 0..100%, and
|
|
.Sq zero
|
|
which clears out the cache in case you want to store new samples.
|
|
.El
|
|
.Pp
|
|
Note that if the IRQ on the Wavelan card is incorrect, the interface
|
|
will be configured, but will not function. The
|
|
.Nm
|
|
program should then be used to reconfigure the card to a sensible
|
|
value.
|
