Required Ports for vCenter Server and Platform Services Controller
The vCenter Server system both on Windows and in the appliance, must be able to send data to every
managed host and receive data from the vSphere Web Client and the Platform Services Controller services.
To enable migration and provisioning activities between managed hosts, the source and destination hosts
must be able to receive data from each other.
Ports Required for Communication Between Components
If a port is in use or is blacklisted, the vCenter Server installer displays an error message. You must use
another port number to proceed with the installation. There are internal ports that are used only for inter-
process communication.
VMware uses designated ports for communication. Additionally, the managed hosts monitor designated
ports for data from vCenter Server. If a rewall exists between any of these elements, the installer opens the
ports during the installation or upgrade process. For custom rewalls, you must manually open the required
ports. If you have a rewall between two managed hosts and you want to perform source or target activities,
such as migration or cloning, you must congure a means for the managed hosts to receive data.
N In Microsoft Windows Server 2008 and later, rewall is enabled by default.
If you congured a custom port when you installed the source vCenter Server instance, revert to default port
values before you proceed with the migration.

80 TCP vCenter Server requires port 80 for
direct HTTP connections. Port 80
redirects requests to HTTPS port 443.
This redirection is useful if you
accidentally use hp://server instead
of hps://server.
WS-Management (also requires port
443 to be open).
If you use a Microsoft SQL database
that is stored on the same virtual
machine or physical server as the
vCenter Server, port 80 is used by the
SQL Reporting Service. When you
install or upgrade vCenter Server, the
installer prompts you to change the
HTTP port for vCenter Server.
Change the vCenter Server HTTP
port to a custom value to ensure a
successful installation or upgrade.
I You can change this port
number during the vCenter Server
and Platform Services Controller
installations on Windows.
