.Sh DESCRIPTION
|
|
.Nm
|
|
is the user-land control program for the Lan Media SSI,
|
|
HSSI, and DS3 network interfaces.
|
|
The SSI is the LMC1000, and runs at various speeds up to 10Mbps.
|
|
The DS3 is the LMC5245 and runs at a speed of 45Mbps.
|
|
The HSSI is the LMC5200, and has no internal clock generator.
|
|
.Nm
|
|
is used to configure various media and protocol options dealing with HDLC
|
|
serial links and hardware configurations.
|
|
.Pp
|
|
When no change is specified on the command line, the interface status is
|
|
displayed.
|
|
.Pp
|
|
The command-line options for
|
|
.Nm
|
|
are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl i Ar interface
|
|
Use the specified
|
|
.Ar interface
|
|
name rather than the default of lmc0.
|
|
.It Fl l Ar speed
|
|
(SSI card only)
|
|
Set the interface to use a clock speed of
|
|
.Ar speed .
|
|
This is only used if the clock source is set to internal clocking.
|
|
.It Fl c
|
|
(SSI, HSSI)
|
|
Set the interface to use external clocking.
|
|
This is the default.
|
|
.It Fl C
|
|
(SSI, HSSI)
|
|
Set the interface to use internal clocking.
|
|
On the SSI card this uses the internal baud rate generator.
|
|
On the HSSI card it uses the PCI bus clock.
|
|
.It Fl e
|
|
Select 16-bit CRC.
|
|
This is the default.
|
|
.It Fl E
|
|
Select 32-bit CRC
|
|
.It Fl k
|
|
Enable Cisco HDLC keepalive protocol.
|
|
This is the default.
|
|
.It Fl K
|
|
Disable Cisco HDLC keepalive protocol.
|
|
.It Fl s
|
|
(DS3)
|
|
Disable the DS3 scrambler function.
|
|
This is the default.
|
|
.It Fl S
|
|
(DS3)
|
|
Enable the DS3 scrambler function.
|
|
.It Fl o
|
|
(DS3)
|
|
Program the card for cable lengths of less than 100 feet.
|
|
In this mode, the card uses lower power to transmit data
|
|
for short cable runs, which might otherwise overdrive a receiver.
|
|
This is the default, and will work in most
|
|
situations even with runs more than 100 feet.
|
|
.It Fl O
|
|
(DS3)
|
|
Program the card for cable lengths greater than 100 feet.
|
|
.El
|
|
.Sh EXAMPLES
|
|
To set a SSI card for a speed of 2048000 bits/sec with HDLC keepalive off,
|
|
one could use:
|
|
.Bd -unfilled -offset indent
|
|
lmcctl -i lmc0 -l 2048000 -K
