atm.conf(4) Kernel Interfaces Manual atm.conf(4)NAME
atm.conf - default ATM configuration file
DESCRIPTION
The atm.conf file is the default ATM configuration file that is processed by running the atmconfig source command. The atm.conf file is a
text file that contains atmconfig commands used to configure and start the ATM network. Each line in the file contains exactly one command
or a comment, if the line begins with the number sign (#). Blank lines are ignored.
See atmconfig(8) for a description of valid commands.
The /etc/atm.conf file is defined as a Context-Dependent Symbolic Link (CDSL), and must be maintained as such. See the System Administra-
tion manual for more information.

atmconfig -- ATM configuration tool
SYNOPSIS
atmconfig [-htv] [command [sub-command [...]]] [options] [arg ...]
DESCRIPTION
The atmconfig tool is used to configure the Netgraph ATM network sub-system.
The command line of atmconfig 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.
Common Options
The following common options change the overall behaviour of atmconfig:
-h Print a very short usage info and exit.
-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.
-v Be more verbose.
Obtaining Help
The help command has a number of useful sub-commands.
To get general help use:
atmconfig help
To get a list of available commands use:
atmconfig help commands
To get a list of available sub-commands use:
atmconfig help command
or (if there are deeper levels of sub-commands):
atmconfig help command sub-command ...
To get a list of options and arguments for a command use:
atmconfig help command sub-command ...
(given that there are no further sub-command levels).
To get a list of common options use:
atmconfig help options
The diag Command
The diag command allows the inspection of the ATM interfaces on the local host and the modification of device parameters. Sub-commands are:
list (print a list of interfaces), config (print hardware configuration), phy (access PHY chip), stats (print statistics) and vcc (print list
of VCCs).
atmconfig diag list
This sub-command lists all ATM interfaces in the system. It takes no options or arguments.
atmconfig diag config [-atm] [-hardware] [device ...]
This command prints the configuration of ATM interfaces. If no device is given, all devices are listed, otherwise only the specified
devices. The option -atm instructs the command to print ATM layer configuration parameters like the number of VCI and VPI bits,
whereas the -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 -atm.
atmconfig diag phy print [-numeric] device
This command prints the PHY registers in a (potential) human comprehensible format. If -numeric is given, the format is hex bytes.
Otherwise, textual representation will be printed.
atmconfig diag phy show [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.
atmconfig diag phy set device reg mask val
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 mask is one are set to the values of the corresponding bits in val. All register bits
that have a zero in mask are written back with their original value.
atmconfig diag phy stats [-clear] device
Print the PHY statistics for the given device. When the optional -clear is given, the statistics are cleared atomically.
atmconfig diag vcc [-abr] [-channel] [-traffic] [device]
Retrieve the list of currently active channels on either all or the specified interfaces. For each channel, the following informa-
tion is printed depending on the options (default is -channel).
-abr Print ABR specific traffic parameters: ICR, TBE, NRM, TRM, ADTF, RIF, RDF, CDF.
-channel Print basic information: VPI, VCI, AAL, traffic type, MTU and flags.
-traffic Print traffic parameters: PCR, SCR, MBS, MCR.
atmconfig diag stats device
Print driver specific statistics.
The natm Command
The natm command is used to change natmip(4) routes on the local host. The sub-commands for the routing table are: add (to add a new route),
delete (to delete an existing route) and show (to print the currently installed NATM routes).
atmconfig natm add dest device vpi vci encaps
atmconfig natm add dest device vpi vci encaps ubr [pcr]
atmconfig natm add dest device vpi vci encaps cbr pcr
atmconfig natm add dest device vpi vci encaps vbr pcr scr mbs
atmconfig natm add dest device vpi vci encaps abr pcr mcr icr tbe nrm trm adtf rif rdf cdf
Add a new route to the routing table. The destination address (the address on the other end of the link) is given in dest. The
device, vpi and vci arguments are the name of the ATM device and the VPI and VCI values for the link. The encaps argument may be
either AAL5 or 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 max-
imum bursts size. The last form of the command adds an ABR (available bit rate) channel.
atmconfig natm delete dest
atmconfig natm delete device vpi vci
This commands deletes an NATM route. The route may be specified either by the destination address or by the device, vpi and vci
triple.
atmconfig natm show
List all NATM routes.
