Migration Considerations

HP NonStop TCP/IPv6 Migration Guide—524524-004

DEFINEs

NonStop TCP/IPv6 has one new DEFINE:

Dynamic Linked Library (DLL)

Unlike Parallel Library TCP/IP, for NonStop TCP/IPv6, you do not need to define the

shared runtime library (SRL) before using TCP6SAM.

Event Messages

Event messages show ZTC6 in the display, and new event messages have been

introduced. See the Operator Messages Manual for information about the new operator

messages.

Management Interfaces

Subsystem Name and ID

The subsystem ID for Parallel Library TCP/IP is ZTCP. The subsystem ID for NonStop

TCP/IPv6 is ZTC6.

TCPIPV6 replaces PTCPIP as the subsystem name and should be used when

requesting SCF help.

SCF

The SCF interface has been changed to support the INET6 and DUAL modes of

NonStop TCP/IPv6. For complete reference information about SCF and the SCF

command syntax, see the TCP/IPv6 Configuration and Management Manual. See also

SCF on page 2-5 for information about the SCF interface to TCP6SAM.

Modes

NonStop TCP/IPv6 has three operating modes: INET, INET6, and DUAL. In INET

mode, NonStop TCP/IPv6 functions in the same manner as Parallel Library TCP/IP

and supports TCP/IP version 4 (IPv4) communications. In INET6 mode, NonStop

TCP/IPv6 supports TCP/IP version 6 (IPv6) communications. In DUAL mode, NonStop

TCP/IPv6 supports both IPv4 and IPv6 communications. IPv6 is an Internet

Engineering Task Force (IETF) standard that extends the 32-bit address of IPv4 to 128

bits.

=TCPIP^NODE^FILE Specifies the name of the IPNODES file to be
