What’s difference between listener tcp port and tcp port in properties of QM?

Don't think there is any.

The Port in the qm.ini file is the default port, one use is when you don't specify a port number on a conname:
http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp?topic=/com.ibm.mq.csqzae.doc/csqzae10100.htm

There are other uses, for example in cluster channel definitions, and the defaul port for the runmqlsr command.

thanks for your help.

I had MQ (windows v6.0), and understand use of tcp port of listener, but there's other TCP port definition in QM's property(eg, test.queue.manager.test - property), what's its use?

Thanks again.

I assume you are looking at these properties in the MQ Explorer? the tcp port on a queue manager is in reality the port in the qm.ini file (or registry on windows)

If you create a listener with a port of zero (0) then when started it will use the port defined against the queue manger instead. By default this is 1414.

This port number on a queue manager isn't used for anything other than supplying the default port number.

But the question is, where is the "default port" used? And its used for more than just the listener, see my post above ....
