You can now enable IP version 6 (IPv6) communication between
any two IBM Tivoli Monitoring components;
possible configurations include communications between the portal server and
the hub monitoring server,
a remote monitoring server and
the hub, or an agent and a hub.
IPv6 is not supported for sending EIF events from the hub monitoring
server or from monitoring agents.
To use this capability, your IBM Tivoli Monitoring environment
must be configured and enabled for IPv6 communication. IPv6 communication
over IPv4-only networks is not supported.
Before components can be enabled for IPv6 communication, the following
requirements must be met:
- The host on which the components are located must be enabled for
IPv6.
- If the component needs to communicate using IPv6 with some components
and IPv4 with others, the host must be enabled for dual-stack operation.
Note: A
dual-stack host provides two discrete network layers. The term stack here
refers to the protocol stack, a suite of protocols used in computer
networking software.
- The host must have DNS or hosts file entries for both IPv4 and
IPv6 addresses. The host must also be configured to resolve host names
and IP addresses from the DNS or from the hosts file.
- The network path between the two components must be enabled for
IPv6 traffic. Tunneling of IPv6 traffic over IPv4 networks is not
supported.
Table 1 shows the supported
combinations of IPv6 with IPv4 across the various
IBM Tivoli Monitoring components.

Note: - All agents running on a computer must be configured
to use the same protocol, either IPv4 or IPv6.
- In scenarios where some agents are on IPv4 only computers
or the network between the agents and the monitoring servers
they report to is IPv4 only, these agents need to communicate with
the monitoring servers
over IPv4. The monitoring servers
therefore may communicate with some agents over IPv4 and with others
over IPv6.
- The portal server does
not support IPv6 on the Windows platform.
If the portal server is
on Windows, the browser and
desktop clients need to communicate with it using IPv4.
- Components do not operate in dual-stack mode on the
Solaris platform. Components can be configured to communicate using
either IPv4 or IPv6. Thus, if a hub server on a Solaris host is configured
to use IPv6, the portal server,
all remote servers, and all agents connecting to the hub must be configured
to use IPv6 for communicating with the hub.
- On HP-UX, patch PHNE_29445 is required for IPv6 support.
- Components do not operate in dual-stack mode on the
HP-UX HP9000 platform. Dual-stack mode is supported on the HP-UX Integrity
platform.
- On Linux computers,
a minimum kernel level of 2.6 is required for IPv6 support.
