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

NOTE: If the destination host is only reachable through a gateway, you must have a route to that
host (a host or a net route).
The IP address in the table must belong to the same IP subnet as a configured card in your system,
and this card must be already started when you initialize IP routing with the command:
/usr/sbin/x25init -a /etc/x25/ip_to_x121_map
NOTE: In case, the IP-to-X.121 map table needs to be specified for an XoL interface, the x25init
command must be issued with the –c, –L and –a options in the same line:
/usr/sbin/x25init –c <XoL interface config file> -L <LLc2 config file>
-a <ip to x121 map file>
If the IP address does not correspond to a configured card, the X.25 product does not know which
interface to use to send packets. Therefore, you must place this information in your /etc/x25/
ip_to_x121_map file by adding the x25_card_device parameter as shown in the syntax
example below. This is a manual procedure that cannot be done in SMH.
Syntax for SVCs
IP_address X.121_address [{+URC|-URC}][+ARC|-ARC}] device=x25_card_device,
packet_size, window_size [CUG=n]
Syntax for PVCs
IP_address X.121_address pvc=n name=prog_access_name
NOTE: If you do not include the packet_size and window_size values, and the
x25_card_device is the last field, the default values will be applied to the packet_size and
window_size fields.
Example
15.128.174.04 12345 -URC -ARC
30.0.0.2 34567 -URC -ARC device=x25_0,256,7
In this example, a card has been configured with a device equal to x25_0, a packet size of 256,
and a window size of 7.
You can then use the gated or route add command to send datagrams to the IP address,
30.0.0.2, routed through your X.25 network to the address, 34567. These packets will be sent
out through the X.25 card that corresponds to the device x.25_0.
File mapping parameters
IP_address Specifies a valid IP address in standard dot notation form:
n.n.n.n
wheren is a number from 0 to 255 inclusive.
X.121_address Specifies the corresponding X.121 address for the host with the above
IP address.
pvc=n Specifies which permanent virtual circuit should be used for the X.121
destination. The value pvc= is a keyword set to n, which is an integer
variable indicating the lci of the permanent virtual circuit. This
keyword/variable pair is specified only when a permanent virtual
circuit is to be used for IP access. When it is not specified, the default
value of a two-way SVC is assumed. The following information is
provided for reference only. Because pvc describes a permanent circuit
for a particular interface, that interface must have been initialized prior
to the initialization of the address map table. If the interface or the
specified PVC does not exist, an error is reported.
