Setup for IP CIP Support
There are other dialogs with the setup script if you choose conventional TCP/IP
support, or support for both types of support.
LNP Support for TCP/IPv6
LNP can be viewed as an instance of the Conventional TCP/IP (T9551) process that
spans all CPUs within a system. Each LNP can logically be viewed as a different
Conventional TCP/IP process running on the system with its own set of IP addresses.
An IP address used on one LNP cannot be used on a different LNP. Applications on
one LNP are isolated from applications on different LNPs on the same system in the
same way they would be if using different Conventional TCP/IP processes.
Communication between such applications will only be through the attached local area
networks. TCP/IPv6 does not forward internal packets between partitions.
With LNP configured, iTP Secure WebServer is able to bind and listen on multiple
TCPIPv6 transports and servers across multiple networks. Additionally, when LNP is
configured over TCP/IPv6, iTP Secure WebServer is able to listen on all combinations
of IP and port from the list of configured combinations provided by the user. For using
LNP feature of iTP Secure WebServer it is necessary that LNP be properly configured
on the system.
A typical configuration for enabling iTP WebServer to work with LNP requires a proper
system-level TCP/IPv6 LNP configuration and proper changes in the iTP Secure
WebServer's configuration file (multiple Accept directives). For example, if there are
four TCP/IPv6 transport processes, namely $ZSAM0, $ZSAM1, $ZSAM2, $ZSAM3,
running on a system configured on four different IP addresses, then iTP WebServer's
configuration file must specify the following:
Accept -transport /G/ZSAM0 -port 80 -address 172.31.24.12
Accept -transport /G/ZSAM1 -port 80 -address 172.31.24.13
Accept -transport /G/ZSAM2 -port 80 -address 172.31.24.14
Accept -transport /G/ZSAM3 -port 80 -address 172.31.24.15
It is noteworthy that in this case, it becomes mandatory to mention address and port
attribute for each of the Accept directives. However, the order of the Accept
directives is not relevant in this case.
Setup for IP CIP Support
In addition to scanning for conventional TCP/IP processes, Parallel Library TCP/IP and
TCP/IPv6, the setup script checks for the presence of CIPSAM processes on the target
Note. For more information on system configuration of LNP, see the TCP/IPv6 Configuration
and Management Manual.
Note. The LNP feature is supported on systems running J06.04 and later J-series RVUs and
H06.15 and later H-series RVUs.
