Constraints
•
Applications: Applications may need to change to run on NonStop TCP/IPv6. See
Applications on page 3-11. In addition, with NonStop TCP/IPv6, you can restrict
access to network interfaces by using the logical network partitioning feature. See
Applications: Restricting Access to Network Interfaces on page 3-2.
•
Configuration Files: There is a new TCP/IP configuration file called IPNODES
and a required change to an existing TCP/IP configuration file. See Configuration
Files on page 3-12.
•
DEFINEs: There are new system DEFINEs. See Configuring Applications to Use
NonStop TCP/IPv6 on page 2-5 and DEFINEs on page 3-13.
•
Dynamic Linked Library: NonStop TCP/IPv6 uses a DLL on H-series RVUs. You
do not have to do anything for DLL usage; it is used automatically by the
subsystem. See Dynamic Linked Library (DLL) on page 3-13.
•
EMS: There are some changes to EMS. See Event Messages on page 3-13.
•
Management Interfaces: There are differences in the SCF and SPI interfaces to
NonStop TCP/IPv6. See Management Interfaces on page 3-13.
•
Modes: NonStop TCP/IPv6 has three operating modes. See Modes on page 3-13.
•
Multicast: There are changes to multicast operations. See Multicast Operations on
page 3-14.
•
Name Changes: Many of the common objects in Parallel Library TCP/IP have
changed. See Name Changes on page 3-14.
•
Processes and Protocols: There is a new process and new protocols available in
NonStop TCP/IPv6. See Processes and Protocols on page 3-15.
•
Retransmission Timer Enhancements: There are new attributes and new socket
options available. See Retransmission Timer Enhancements on page 3-15.
Constraints
The following alphabetical list of constraints is organized by a keyword that describes
the topic.
•
Adapter Support: The token-ring ServerNet adapter (TRSA) and the ATM
ServerNet adapter (ATM3SA) are not supported. (Only Ethernet adapters are
supported by NonStop TCP/IPv6.)
•
Domain Name System (DNS) Support: NonStop TCP/IPv6 in INET6 mode or in a
pure IPv6 network does not support DNS queries.
•
Parallel Library TCP/IP: Parallel Library TCP/IP and NonStop TCP/IPv6 cannot
run on the same system.
•
Protocol Support: ATM and X.25 and SNAP type SUBNETs are not supported.
