How do I change Fedora 25 SSH port?

Steps already tried:

1) In /etc/ssh/ssh_config I have uncommented the line consisting of # Port 22 and change 22 to a a random one, e.g.: 50687. Additionally I uncommented the # Host * line.

2) I tried creating a new line consisting of:

Port 50687

at the bottom of the file.

3) /etc/ssh/ssh_config has the note:

# To modify the system-wide ssh configuration, create a  *.conf  file under
#  /etc/ssh/ssh_config.d/  which will be automatically included below
Include /etc/ssh/ssh_config.d/*.conf

The only file in .../ssh_config.d/ is 05-redhat.conf

Again I tried uncommenting (and modifying) the # Host 22* line and creating a new line at the bottom of the.

4) I created a file 06-myfile.conf conisisting only of either:

Port 50687


Host *
Port 50687

After completing any of these steps I have issued:

sudo systemctl restart sshd.service

and tried to connect (via port 50687) and/or:

sudo systemctl status sshd.service
[sudo] password for spaceman:

What utterly n00bish error am I making?
