Port Numbers

A standard installation sets the following port numbers for an InterSystems IRIS instance:

Superserver port number — 1972. If taken, then 51773 or the first available subsequent number.
Telnet — 23

You can assign different port numbers during a new installation by performing a Custom installation (see Setup Type). You cannot enter a port number greater than 65535.

For information about setting the port numbers on an already-installed instance of InterSystems IRIS, see Set Port Numbers.
