Which port is used to access the VAMI for the vCenter Server Appliance?

The vCenter Server Appliance Management Interface (VAMI) is specifically designed for managing various aspects of the vCenter Server Appliance, such as networking configuration, certificate management, and system updates. This interface is accessed through a web browser using a specific port.

The correct port for accessing the VAMI is 5480. When you navigate to the VAMI, you would typically do so by entering the appliance's IP address or hostname followed by :5480 in your web browser (e.g., https://:5480). This port is explicitly defined for VAMI to ensure that management traffic is separated from other types of traffic that the appliance might handle, contributing to both security and organization in network services.

Understanding the purpose of the other ports helps clarify why 5480 is the correct choice. Port 8080 is generally used for HTTP traffic, which is not related to the VAMI. Port 443 is used for secure HTTPS traffic, which is commonly associated with accessing vCenter Server itself, but not specifically for the management interface. Port 9850 does not relate to typical vSphere processes or interfaces. Thus, 5480 is the designated and correct port for VAMI access within a vCenter Server Appliance.
