How to Access NonStop TCP/IPv6
•
For DUAL mode,
1. Alter the MON to DUAL mode:
->ALTER MON $ZZTCP.*, FAMILY DUAL
2. Add the SUBNET and specify FAMILY as DUAL:
->ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, FAMILY DUAL, &
DEVICENAME LAN02, IPADDRESS 1.2.3.4, IPV6RAENABLE ON
•
For DUAL mode with Ethernet failover, in the ADD SUBNET command, specify
FAMILY as DUAL. For examples of Ethernet failover in DUAL mode, see Section 1,
Quick Start.
When the NonStop TCP/IPv6 subsystem is configured with only IPv4 SUBNETs, the
NonStop TCP/IPv6 subsystem becomes a direct replacement for the Parallel Library
TCP/IP subsystem (which is not supported on Integrity NonStop servers). IPv6
applications still function but only in IPv4 mode. If the subsystem is configured with
only IPv6 native mode, IPv4 applications will not function.
In DUAL mode, NonStop TCP/IPv6 automatically adds a tunnel, which is a SUBNET of
TYPE TUN with the reserved name of TUN. You can also add your own configured
tunnel. For more information about tunnels, see How IPv6 Tunnels Work on page A-18.
For examples of adding a configured tunnel, see Section 1, Quick Start and Section 8,
SCF Reference for NonStop TCP/IPv6.
How to Access NonStop TCP/IPv6
You must select TCP6SAM as the TCP/IP transport-service provider if you want your
applications to use NonStop TCP/IPv6 instead of conventional TCP/IP. The SCF
LISTDEV command display in Example 2-1 on page 2-21 shows conventional TCP/IP
processes and NonStop TCP/IPv6 processes. Example 2-2 on page 2-22 shows the
LISTDEV display for conventional TCP/IP and Parallel Library TCP/IP. The program
names are highlighted to show the difference between the Parallel Library TCP/IP
process name and the NonStop TCP/IPv6 process name and the process names are
also highlighted.
Note. NonStop TCP/IPv6 and Parallel Library TCP/IP cannot coexist on the same NonStop
S-series system, so these displays are from two different systems. (Parallel Library TCP/IP is
not supported on Integrity NonStop servers.)
