.Sh NAME
.Nm atmconfig
.Nd "ATM configuration tool"
.Sh SYNOPSIS
.Nm
.Op Fl htv
.Op Ar command Op Ar sub-command Op ...
.Op Ar options
.Op Ar arg ...
.Sh DESCRIPTION
The
.Nm
tool is used to configure the Netgraph ATM network sub-system.
.Pp
The command line of
.Nm
generally consists of common options followed by a command string, optionally
followed by sub-command strings, optional command specific options and
command specific arguments.
Commands and sub-commands as well as command
specific options may be abbreviated as
long as there is only one match possible.
.Ss Common Options
The following common options change the overall behaviour of
.Nm :
.Bl -tag -width indent
.It Fl h
Print a very short usage info and exit.
.It Fl t
Several show-type commands output a header and then several lines
of information.
If this option is given, the header is omitted, simplifying the parsing
of the output.
.It Fl v
Be more verbose.
.El
.Ss Obtaining Help
The
.Ic help
command has a number of useful sub-commands.
.Pp
To get general help use:
.D1 Nm Ic help
.Pp
To get a list of available commands use:
.D1 Nm Ic help Cm commands
.Pp
To get a list of available sub-commands use:
.D1 Nm Ic help Ar command
.Pp
or (if there are deeper levels of sub-commands):
.D1 Nm Ic help Ar command sub-command ...
.Pp
To get a list of options and arguments for a command use:
.D1 Nm Ic help Ar command sub-command ...
(given that there are no further sub-command levels).
.Pp
To get a list of common options use:
.D1 Nm Ic help Cm options
.Ss The Ic diag Ss Command
The
.Ic diag
command allows the inspection of the ATM interfaces on the local host
and the modification of device parameters.
Sub-commands are:
.Cm list
(print a list of interfaces),
.Cm config
(print hardware configuration),
.Cm phy
(access PHY chip),
.Cm stats
(print statistics) and
.Cm vcc
(print list of VCCs).
.Bl -tag -width indent
.\"----------------------------------------
.It Nm Ic diag Cm list
This sub-command lists all ATM interfaces in the system.
It takes no options or arguments.
.\"----------------------------------------
.It Xo
.Nm Ic diag Cm config
.Op Fl atm
.Op Fl hardware
.Op Ar device ...
.Xc
This command prints the configuration of ATM interfaces.
If no
.Ar device
is given, all devices are listed, otherwise only the specified devices.
The option
.Fl atm
instructs the command to print ATM layer configuration parameters like
the number of VCI and VPI bits, whereas the
.Fl hardware
option requests card specific information like the vendor or the serial
number.
If none of the options is given, the defaults is to assume
.Fl atm .
.\"----------------------------------------
.It Xo
.Nm Ic diag Cm phy print
.Op Fl numeric
.Ar device
.Xc
This command prints the PHY registers in a (potential)
human comprehensible format.
If
.Fl numeric
is given, the format is hex bytes.
Otherwise, textual representation will be printed.
.\"----------------------------------------
.It Nm Ic diag Cm phy show Op Ar device ...
This sub-command prints static information about the PHY device used
in the ATM card like the type of the PHY and the media.
.\"----------------------------------------
.It Xo
.Nm Ic diag Cm phy set
.Ar device
.Ar reg
.Ar mask
.Ar val
.Xc
This sub-command allows one to change bits in PHY registers.
This should be used with great care.
The bits of the given PHY chip register for which the corresponding bit in
.Ar mask
is one are set to the values of the corresponding bits in
.Ar val .
All register bits that have a zero in
.Ar mask
are written back with their original value.
.\"----------------------------------------
.It Xo
.Nm Ic diag Cm phy stats
.Op Fl clear
.Ar device
.Xc
Print the PHY statistics for the given
.Ar device .
When the optional
.Fl clear
is given, the statistics are cleared atomically.
.\"----------------------------------------
.It Xo
.Nm Ic diag Cm vcc
.Op Fl abr
.Op Fl channel
.Op Fl traffic
.Op Ar device
.Xc
Retrieve the list of currently active channels on either all
or the specified interfaces.
For each channel, the following information is printed depending
on the options (default is
.Fl channel ) .
.Bl -tag -width ".Fl traffic"
.It Fl abr
Print ABR specific traffic parameters: ICR, TBE, NRM, TRM, ADTF, RIF, RDF,
CDF.
.It Fl channel
Print basic information: VPI, VCI, AAL, traffic type, MTU and flags.
.It Fl traffic
Print traffic parameters: PCR, SCR, MBS, MCR.
.El
.\"----------------------------------------
.It Nm Ic diag Cm stats Ar device
Print driver specific statistics.
.El
.Ss The Ic natm Ss Command
The
.Ic natm
command is used to change
.Xr natmip 4
routes on the local host.
The sub-commands for the routing table are:
.Cm add
(to add a new route),
.Cm delete
(to delete an existing route) and
.Cm show
(to print the currently installed NATM routes).

.Cm abr Ar pcr mcr icr tbe nrm trm adtf rif rdf cdf
.Xc
Add a new route to the routing table.
The destination address (the address
on the other end of the link) is given in
.Ar dest .
The
.Ar device ,
.Ar vpi
and
.Ar vci
arguments
are the name of the ATM device and the VPI and VCI values for the link.
The
.Ar encaps
argument
may be either
.Cm AAL5
or
.Cm LLC/SNAP
both of which specify AAL5 encapsulation, the first one without additional
encapsulation, the second one with LLC/SNAP headers.
The first two forms of the command add an UBR (unspecified bit rate) channel,
where the second form allows the optional specification of a peak cell
rate (PCR).
The third form adds a CBR (constant bit rate) channel where a PCR
must be given.
The fourth form adds a VBR (variable bit rate) channel.
The arguments are the peak cell rate, the sustainable cell rate and the
maximum bursts size.
The last form of the command adds an ABR (available bit rate) channel.
.\"----------------------------------------

.Ar vpi
.Ar vci
.Xc
This commands deletes an NATM route.
The route may be specified either by the destination address or
by the
.Ar device , vpi
and
.Ar vci
triple.
.\"----------------------------------------
.Pp
.It Nm Ic natm Cm show
List all NATM routes.
