Startup Files for GTWY1
the files will be discussed: the most obvious differences are that there will be a single
NonStop TCP/IP process ($ZTC0) and different routes will be added.
The TCPIPUP3 File
As the TCPIPUP3 file in Example F-4 shows, the only significant difference from the
file for HOST1 (The TCPIPUP2 File
on page F-5) is that a second NonStop TCP/IP
process is not started. As a result, there is neither a second LISTNER nor a second
TELSERV process.
The SCFSBNT File
The SCFSBNT file for GTWY1 is different in several respects from that for HOST1. The
most notable difference is that there is a single NonStop TCP/IP process ($ZTC0)
instead of two processes. So, instead of adding a single subnet to each NonStop
TCP/IP process, this sample configuration adds two subnets (one for each adapter) to
the single NonStop TCP/IP process.
Note. The NonStop TCP/IP primary and backup processes must be configured in CPU’s that
have access to the SAC; (the SAC corresponds to DEVICENAME in Example F-5
).

Note. Both subnets must be added with the GATEWAY ON attribute set.
