SMICM services

Hi guys,

I've one question that is bothering me for a long time....

In transaction smicm, if you go to services, you can check the ports defined to each protocol...

Well, you can create new ports but if the server goes down, these services will be deleted...How can I turn the created services persistent?Meaning, if the server goes down, I don't have to create them from scratch?

Thanks a lot for the attention
