change SSL port for LTM management

I don't think you can change port. By default, the BIG-IP system allows access to only a limited set of the available ports. https://support.f5.com/kb/en-us/solutions/public/13000/200/sol13250.html

Acctually I do not want to change ssl port just add different port for managment purpose .

I think it's not possible (at least not documented). TMSH command "list sys httpd sys httpd" do not show any of such option.

thx cjunior, its new security requirement.

Hey cjunior, you have added the green color part under the httpd ?

1. Use SSH to log in to the virtual machine using the Public IP address.
2. Move the port that is used to access the user interface from port 443 to some other port (such as 8443) using a tmsh command. modify sys httpd ssl-port 8443
3. Add your new port (8443 in this example) to the default self allow port list (required for single NIC deployment) using a tmsh command. modify net self-allow defaults add { tcp:8443 }
4. From the tmsh prompt, save the changes to the system configuration. save sys config
5. End the SSH session on the virtual machine.
