vCenter server is used to manage the multiple ESXi hosts & virtualized environment from a single pane. vCenter Server needs to be installed on Windows server. vCenter server connects the ESXi host through the network. So for connecting to the ESXi hosts & other components vCenter requires some of the network ports to be open for successful connectivity. Here I am listing some of the ports which are required to successful connectivity between vCenter & other components.
vCenter Server 6 Ports requirements:
| Port Number | Protocol | Description |
