Configuration 3: Startup Files for Two Hosts Using
an X25AM-Based Connection
The following commands add five more SUs to this line. These SUs allow the NonStop
TCP/IP process to communicate with the X25AM I/O process to establish an X.25
circuit over which the TCP/IP communication can occur:
ADD SU #TCPIP2, like #TCPIP1
ADD SU #TCPIP3, like #TCPIP1
ADD SU #TCPIP4, like #TCPIP1
ADD SU #TCPIP5, like #TCPIP1
ADD SU #TCPIP6, like #TCPIP1
A TCP/IP process uses up to 32 SUs on each X25AM line; so, you can create up to 32
SUs. The naming convention of these SUs is assumed by the TCP/IP process to be
#TCPIPn, where n is a number from 1 through 32.
When you configure a NonStop TCP/IP process, you add a SUBNET object type of
X.25. An attribute of the X.25 SUBNET is the X.25 line name ($X250 in this case).
When that SUBNET object is started, the NonStop TCP/IP process communicates with
the X25AM I/O process by trying to open SUs that have the name #TCPIPn. The
NonStop TCP/IP process continues opening SUs until NonStop TCP/IP opens the last
SU (#TCPIP32).
TCPUP1
The command file TCPUP1 starts and configures the TCPIP, LISTNER, and TELSERV
processes. Example 3-8 shows a listing of the command file for TCPUP1.
