This should be the only line that is relevant. Everything else you describe is starting/stoping/changing the server side. Are you using the yum supplied version of ssh? Later on you say that you are starting a file transfer. ssh doesn't do file transfers. Two other tools built over ssh do. SFTP and SCP. For both of those the port parm is a capital P, not the lower case p in your example.
Yum versions should be here by default:
bash-5.1$ which ssh sftp scp
Old SC1 versions are here:
which ssh sftp scp
That said, I'm not aware of any restrictions on either version as far as changing ports. Definitely not at V7R3 where I'm at as almost all my connections are on non standard ports.
