On Oracle Linux (OL), the OpenSSH SSH Daemon (sshd) utilizes port 22 for incoming connection requests from remote OpenSSH SSH (ssh) and Secure File Transfer (sftp) clients.
In some cases, however, System Administrators (SAs) prefer to utilize separate ports to service ssh and sftp activity, such as described by the following document:

sshd was recently re-configured to use additional and/or non-default network ports.
