Do I need to (and how to) restart restart ssh / sshd after changes to config on fedora cloud

I want to change the port of ssh on my Linux cloud machine. In the /etc/ssh/sshd_config file I see:

# If you want to change the port on a SELinux system, you have to tell
# SELinux about this change.
# semanage port -a -t ssh_port_t -p tcp #PORTNUMBER
#
#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

My understanding is that I just need to uncomment the Port line and change the port number - Do I also have to run the command specified in the first three lines (from selinux?)

Lastly, trying to "restart" ssh with no luck. I have tried

sudo /sbin/sshd restart and I get (Extra argument restart.)

In other places I get Error: Access Denied even when I am using sudo.

Can someone please explain to me the exact process to change the port, or any settings in SSH (like if I have to change it in the root / default file or a user file), and how I can / should restart ssh on Fedora Cloud (23)? Thanks!

Fedora uses systemd
systemctl restart sshd
should do the trick

See: https://fedoraproject.org/wiki/Systemd

That is what I thought, however, I still get a Failed to restart sshd.service: Access denied. Changing Selinux to "permissive" with setenforce 0 gives me this message: Failed to restart sshd.service: The name org.freedesktop.PolicyKit1 was not provided by any .service files Any ideas?
