IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Control port number assignments
IBM Tivoli Monitoring assigns port numbers to each component in an installation to be used for communication with other components. Default well-known ports are reserved for major components such as monitoring servers and the portal server. For all other components, an algorithm calculates the listening port to reserve.
You might want to change or add to the default assignments under some conditions, for example, when the default port assigned to a monitoring agent has already been reserved by another application, or the portal server requires a second port number for communication through a firewall with Network Address Translation (NAT).
- Configure port number assignments for the monitoring server
The default IP.UDP, IP6.UDP, IP.PIPE, and IP6.PIPE listening port setting for the Tivoli Enterprise Monitoring Server is 1918. For IP.SPIPE and IP6.SPIPE, it is 3660. For SNA, it is 135.
- Configure port number assignments for the monitoring automation server
The default port number that the Tivoli Enterprise Monitoring Automation Server listens on for incoming HTTP requests is 10001. The default port for listening for HTTPS incoming requests is 10002.
- Configure port number assignments for the portal server
Communications between Tivoli Enterprise Portal clients and the Tivoli Enterprise Portal Server are controlled by a portal server interface definition.
- Configure port number assignments for monitoring agents
If multiple Tivoli Monitoring agents are installed on the same system, they cannot share the same port number for IP.PIPE and IP6.PIPE, or IP.SPIPE and IP6.SPIPE communications. An automatic mechanism has been developed to allocate additional ports for communications to the monitoring server. IBM Tivoli Monitoring uses the following algorithm to allocate port numbers for monitoring agents to reach the monitoring server: reserved port = well-known port + (N*4096)
