atmsigd.conf contains configuration data for atmsigd. atmsigd reads atmsigd.conf after parsing the
command line options, before connecting to the ATM network.
Configuration parameters are arranged in functional groups. In order to set a parameter, the name of the
group, the name of the parameter, and the parameter value(s) have to be specified, e.g.
sig level debug
decreases the logging threshold for messages related to signaling to the debug level. The following
options are recognized:
debugdumppath
Specifies the directory to which atmsigd will write status and trace dumps. If tracing is not yet
enabled, the trace size is automatically set to a (small) default value.
debuglevellevel
Sets the default debug level to level. level can be any of debug, info, warn, error, and fatal.
Only messages with the same or a higher priority than the debug level are printed. Note that the
command-line option -d generates even more output (e.g. hexdumps of all packets passing between
atmsigd and the network) than debugleveldebug.
debuglogpath
Specifies the file to which atmsigd writes logging messages. When using the special file name
syslog, messages are send to the system logger instead. Log messages are written to standard
output if no log file is specified. Writing to standard output can also be explicitly requested by
using the special file name stderr.
debugtrace [number]
Enables tracing and optionally sets the number of entries that should be kept in the trace buffer.
A (small) default is used if the number is omitted.
iolevellevel
Sets the debug level for IO-related messages to level.
iomax_raterate
Sets the rate to signal if an application requests the "maximum". See qos(7) for the syntax to use
for expressing the rate. The default maximum rate is 353207 cells/second (OC3). (Note that the
value of max_rate does not constrain the rates an application can explicitly request.)
ioqosqos
Configures the signaling VC to use the specified QOS (see qos(7) for the syntax). By default, UBR
at link speed is used on the signaling VC.
iovc [itf.]vpi.vci
Uses the specified VC for signaling messages instead of the usual 0.0.5.
saallevellevel
Sets the debug level for messages related to SAAL (i.e. SSCF and SSCOP) to level.
siglevellevel
Sets the debug level for messages related to signaling (Q.2931 or ISP) to level.
sigmodemode
Set the mode of operation. The following modes are available: user for the user side, network for
the network side, and switch for operation in a switch. The default behaviour is user.
siguni30
Use UNI 3.0 signaling. If specified together with siguni31, this option sets UNI 3.1 signaling
with a few backwards-compatibility extensions.
siguni31
Use UNI 3.1 signaling. This option can be combined with siguni30 (see above).
siguni40
Use UNI 4.0 signaling. This option can be combined with sigq.2963.1 (see below).
sigq.2963.1
Enable peak cell rate renegotiation. This option is only available with UNI 4.0 signaling.
sigvpcivpciitfitf
Sets up a very simplistic type of routing. All calls with VPCI values equal to or greater than
vpci will be routed to itf, and their VPI values will be set to the signaled VPCI minus vpci.
Multiple sigvpci entries can be used to support an arbitrary number of interfaces. Example: with
sigvpci4itf1, a call signaled for VPCI/VCI 0.x is routed to 0.0.x, a call signaled for 6.y is
routed to 1.2.y, etc.
policylevellevel
Sets the debug level for messages related to policy decisions to level.
policydecisiondirectionaddress
Takes the specified decision for calls from or to address. decision can be either allow or
reject. direction is either from or to. The address may be wildcarded by prepending a slash and
the number of significant bits (NSAP) or digits (E.164). The rules are searched in the order in
which they appear in atmsigd.conf until the first match. If no rule matches, the call is allowed.
entity [itf.]vpi.vci{options...}
Activates a signaling entity on that specific VC. Multiple entity clauses can appear in the same
configuration. When using entity, the option iovc is not available. entity is optionally
followed by the following options, enclosed in curly braces: vpci (corresponds to sigvpci), mode
(corresponds to sigmode), qos (corresponds to vcqos), route, and default. The last two options
determine how outbound calls are routed. The route option is followed by an address in the format
used for addresses in policy. If no route entry matches the called party number of an outbound
call, the entry marked with default is selected.
When setting multiple parameters in the same group, the group name doesn't have to be repeated if it is
followed by the parameters in curly braces. Example:
debug {
level warn
dump /var/tmp
log syslog
trace 100
}
Line breaks can be inserted in atmsigd.conf wherever spaces or tabs are allowed. Everything between a `#'
and the end of the line is considered a comment. The `#' character cannot be escaped.
If an option is specified in atmsigd.conf and on the command line, the command line has priority.
