Configuring the NonStop TCP/IP Subsystem

Configuration 3: Startup Files for Two Hosts Using
an X25AM-Based Connection
Command Description
ALLOW ALL ERRORS
permits SCF to continue running
commands in the command file regardless
of errors.
ASSUME PROCESS $ZTC1
sets an SCF assumed object. All
subsequent commands apply to this object
unless explicitly entered otherwise.
ALTER SUBNET #LOOP0, IPADDRESS
127.1
sets the IP address for the loopback
SUBNET.
ADD SUBNET #PDN1, TYPE X25,
DEVICENAME $X250, IPADDRESS
128.30.224.11
adds an X25 SUBNET object that has the
name #PDN1 to the TCP/IP process
$ZTC1.
Note. To obtain a list of running X25AM lines to use in the DEVICENAME field, issue the
LISTDEV TYPE 61 at the SCF prompt. The X25AM lines are listed in the Names column.
Subnet names start with a pound sign (#) followed by an alpha character. The remaining six
characters can be any combination of alphanumeric characters. In this case, (#PDN1) PDN
denotes Public Data Network.
$X250 is the X.25 line to service connections.
128.30.224.11 is the IP address associated with the \LA connection to this X.25 PDN.
ALTER SUBNET #PDN1, SUBNETMASK
%HFFFFFF00
sets the subnet mask so that the first three
octets of an IP address determine the
network address.
ADD ADDRMAP #A1, IPADDRESS
128.30.224.12, &
X121ADDR "00000012300000"
maps the IP address of the remote host
with its X.121 source address.
Note. In this sample configuration, the X.121 source addresses of \LA and \NY specified in
the SCRADDR attribute were derived from their IP addresses in accordance with the
specification contained in the Military Standards for X.25. Thus, NonStop TCP/IP could
establish a connection without the ADDRMAP specification. However, if you were to specify
source addresses that were not derived in this way, you would have to include an
ADDRMAP attribute in TPSUBU1and TPSUBU2.
START SUBNET *
places all the $ZTC1 SUBNETs into
service.
START ROUTE *
places all the $ZTC1 routes into
service.
Note. When you add a SUBNET object, you automatically create a default ROUTE object.
No explicit ADD ROUTE command is necessary. Thus, this sample TCPSUBU1 file contains
no ADD ROUTE command. The TCPSUBU1 file does, however, contain the required
START ROUTE command that starts the default routes. For more information, see ROUTE
Object Type on page 4-4, ADD SUBNET Command on page 4-21, and ADD ROUTE
Command on page 4-18.
