Configuration 3: Startup Files for Two Hosts Using
an X25AM-Based Connection
TCPSUBU1
The command file TCPSUBU1 adds an X.25 SUBNET and ADDRMAP specification to
the NonStop TCP/IP process $ZTC1. Example 3-9 shows a listing of the command file
TCPSUBU1:
LISTNER /NAME $ZPORT,
NOWAIT, PRI 160, CPU 2/3
PORTCONF
invokes the LISTNER process using a process
name of $ZPORT.
$ZPORT uses $ZTC1 (TCP/IP process) and
listens for connection requests from the
processes listed in the file PORTCONF.
CPU 2 starts the LISTNER in CPU 2. The
LISTNER can run as a NonStop process pair;
therefore, CPU 3 is specified as backup.
The line:
TELSERV/NAME $ZTN1,CPU
2,NOWAIT,PRI 170/-BACKUPCPU 3
starts the Telserv process in CPU 2, with CPU
3 specified as backup.
Note. To add an X.25 network connection to an existing NonStop TCP/IP subsystem, you do
not need the commands to start TCPIP, LISTNER, and TELSERV processes. But make sure
that the SCF command file TCPSUBU1 assumes the correct NonStop TCP/IP process name.
