IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Choose between IPv6 and IPv4
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, the 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.
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.
Supported IBM Tivoli Monitoring configurations using the IPv6 communications protocol
Valid configurations Portal client Portal server Hub monitoring server and automation server Agents Remote monitoring server Agents (connected to the remote monitoring server) IPv6 only IPv6 IPv6 IPv6 IPv6 IPv6 IPv6 IPv6 with IPv4 IPv4 IPv4 or IPv6 IPv4 or IPv6 IPv41 IPv4 or IPv6 IPv41
- 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.
