The VMware vCenter Server system must be able to send data to every managed host and receive data from every vSphere Web Client. For migration and provisioning activities between managed hosts, the source and destination hosts must be able to receive data from each other.
For information about ports required for vCenter Server on Windows, see Required Ports for vCenter Server.
VMware uses designated ports for communication. Additionally, the managed hosts monitor designated ports for data from the vCenter Server system. The vCenter Server Appliance is preconfigured to use the ports listed in Ports Required for the vCenter Server Appliance. For custom firewalls, you must manually open the required ports. If you have a firewall between two managed hosts and you want to perform source or target activities, such as migration or cloning, you must configure a means for the managed hosts to receive data.
|80||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 http://server instead of https://server.|
|443||The vCenter Server system uses port 443 to monitor data transfer from SDK clients.|
|902||The default port that the vCenter Server system uses to send data to managed hosts. Managed hosts also send a regular heartbeat over UDP port 902 to the vCenter Server system. This port must not be blocked by firewalls between the server and the hosts or between hosts.|
|8080||Web Services HTTP. Used for the VMware VirtualCenter Management Web Services.|
|8443||Web Services HTTPS. Used for the VMware VirtualCenter Management Web Services.|
|10080||vCenter Inventory Service HTTP|
|10443||vCenter Inventory Service HTTPS|
|10109||vCenter Inventory Service database|
|514||vSphere Syslog Collector server|
|1514||vSphere Syslog Collector server (SSL)|
|6500||Network coredump server (UDP)|
|6501||Auto Deploy service|
|6502||Auto Deploy management|
|9090||vSphere Web Client HTTP|
|9443||vSphere Web Client HTTPS|
|5480||vCenter Server Appliance Web user interface HTTPS|
|5489||vCenter Server Appliance Web user interface CIM service|
|22||System port for SSHD|
To have the vCenter Server system use a different port to receive vSphere Web Client data, see the vCenter Server and Host Management documentation.
For a discussion of firewall configuration, see the vSphere Security documentation.
