Port number assignments

Tivoli Management Services reserves a default well-known port for the first process started on a system (normally, the monitoring server). For monitoring agents and other components, an algorithm based on the port number assigned to the monitoring server calculates the listening port to reserve. A port number cannot be assigned to a component if it is already reserved for another component or application.

The default listening port number for the monitoring server is 1918 for IP.PIPE, IP.UDP, IP6.PIPE, and IP6.UDP. For the secure IP protocols (IP.SPIPE and IP6.SPIPE), the default port number is 3660. For SNA, the default is 135. It is generally best to accept the default setting. However, you might find it necessary to change the setting under some conditions; for example, when the port assigned to a component by the algorithm is already reserved by another application or component.
