Ports and Protocols for VMM

 

Updated: December 16, 2016

Applies To: System Center 2012 SP1 - Virtual Machine Manager, System Center 2012 R2 Virtual Machine Manager, System Center 2012 - Virtual Machine Manager

When you install the Virtual Machine Manager (VMM) management server, you can assign some of the ports that it will use for communications and file transfers between various VMM components and other devices. While it is a best security practice to change the default ports, not all of the ports can be changed through VMM. The default settings for the ports are listed in the following tables.

P2V functionality was removed in the System Center 2012 R2 release, and the VMM Self-Service Portal was removed in the System Center 2012 SP1 release. As such, these applicable ports are not listed.

The VMM Management Server communicates with various components and devices over these ports:
