HP-UX IPv6 Transport Administrator's Guide for TOUR 2.0 (April 2004, rev 2)

Features Overview
IPv6 Transport (bundled as part of TOUR 2.0)
Chapter 1 3
IPv6 Transport (bundled as part of TOUR 2.0)
IPv6 is the next generation Internet Protocol. The IPv6 protocol is also
referred to as "IPng" (IP next generation). It provides the infrastructure
for the next wave of Internet devices, such as PDAs, mobile phones and
appliances. It also provides greater connectivity for existing devices such
as laptop computers.
IPv6 was designed by the Internet Engineering Task Force (IETF) to
improve upon the scalability, security, ease of configuration, and network
management capabilities of IPv4.
The following sections highlight IPv6 features available with TOUR 2.0.
Additionally, overview information about features available in TOUR 2.0
but not new to TOUR 2.0 (first introduced in base (default) HP-UX 11i
v2) are included.
HP-UX 11i v2 IPv6 Transport Features Available with
TOUR 2.0
This section describes HP-UX 11i v2 IPv6 transport features available
with TOUR 2.0 (not available in base (default) HP-UX 11i v2).
• netstat Enhanced to Support the Display of 64-bit MIB
Counters: netstat in TOUR 2.0 has been enhanced (for IPv4 and
IPv6) to support the display of 64-bit MIB (Management Information
Base) counters. Thus, some of the netstat fields have the potential
to display widened output. This can cause a wraparound effect on
80-character displays.
• IPoIB (IP over InfiniBand) Link Support: TOUR 2.0 provides
transport support for InfiniBand links that support IPoIB. The
TOUR 2.0 transport software support is required for HP InfiniBand
links to run IPoIB.
The HP-UX networking utilities ifconfig, netstat, lanadmin,
lanscan, arp, rtradvd and ndp have all been enhanced to be
capable of handling IPoIB-related data. (Note that rarp has not been
enhanced for handling IPoIB.)
IPoIB-support only applies on HP-UX 11i v2 (for both IPv4 and
IPv6). IPoIB-supported links are not supported on HP-UX 11i v1.
