HP X.25/9000 User's Guide HP-UX 11i v3 (5900-1523, August 2011)

Each of the 22 parameters has an identifier known as the parameter reference. This identifier is
an integer value from 1 to 22. Each parameter has a defined range of possible values as specified
by the X.3 recommendations.
X.3 parameters are specified in one or more configuration sets contained in the /etc/x25/
x3config file. Each configuration set includes:
• X.3 configuration set name and profile number
• Parameter number
• Parameter value for line mode (value1) and raw mode (value2)
• Comment lines starting with “#”
See “X.25 Configuration files and examples” (page 144) for an example of the x3config file.
Configuration set syntax
The syntax for an X.3 configuration set is shown in the following example:
config_name : profile_number {
# <X.3 parameter_no> <value1> <value2>
1 1 1
2 1 1
. . .
. . .
. . .
22 0 0
}
An X.3 configuration set is a string which embodies the group of X.3 parameters and parameter
values beginning with “{” and ending with “}”. Each configuration set is identified by a configuration
set name (config_name) and an optional profile number (profile_number).
Parameter values
config_name Mandatory. Specifies the configuration set name, a character string
that identifies the X.3 parameter set. Each config_name must be
unique. This is a required parameter for all PAD services if user-defined
X.3 parameters are to be used. This name must match the x3 value
given in the x29hosts file for pad_spt, printer, or pad_uucp
entries. Since X3 has no effect on pad_em entries, a dummy string for
config_name together with a profile number should be entered for
padem profile parameters.
profile_number Optional. Applies only to the padem configuration. This is a number
that must match the number entered for profile in the pad_em {} section
of the x29hosts file. If the profile entry exists and is assigned a value
in the x29hosts file, it must also appear in the x3config file.
X.3_parameter _no Mandatory. This is an integer value from 1 to 22. See “X.3 Parameter
descriptions” (page 113) later in this chapter for a full description of
each X.3 parameter.
value1, value2 Mandatory. These are the values to be used in X.3 configuration. Each
value is defined for a specific X.3 parameter: value1 is for line-mode
configuration; value2 is for raw-mode configuration. Only
x29server implements raw-mode data transfer and only parameters
3 and 4 are used for raw-mode data transfer. x29printd, x29uucpd,
and padem do not use value2.
