difference between Management Interface Reservation and Dedicated Management Port

Hi everyone,

I'm new to the forum, I find many important answers and I think it's a very useful forum! 

I wanted to ask you what was the difference between the "Management Interface Reservation" that is twisted in the settings of the HA and "Dedicated Management Port" that is inside the interfaces and how to manage the authentication ldap, radius etc with the two different modes.

Thanks for your help.

Regards

AI.
