After installing a plug-in, you can modify the plug-in port if required. You can modify only the plug-in port and not the SnapCenter Server port.
You can modify a plug-in port only after the plug-in is installed. If you are 2.x or earlier versions of SnapCenter Server and SnapCenter plug-ins, you must upgrade both SnapCenter Server and SnapCenter plug-ins to be able to modify the plug-in port. You cannot modify the plug-in port while upgrade operations are in progress.
While modifying a plug-in port, you must be aware of the following port rollback scenarios:
If the port was changed for all of the components but one of the components fails to start with the new port, then the old port is retained for all of the components. For example, if you want to change the port for two plug-ins on the stand-alone host and SnapCenter fails to apply the new port to one of the plug-ins, the operation fails (with an appropriate error message) and the old port is retained for both the plug-ins.
For example, if the plug-in is installed on four nodes in a clustered setup, and if the port is not changed for one of the nodes, the old port is retained for all of the nodes.
You can only modify the SnapCenter port if the SnapCenter Plug-in for VMware vSphere was installed using the SnapCenter GUI Add Host wizard.
The SnapCenter port default is 8144 and is used by the plug-in to communicate with the vCenter Server and with the SnapCenter Server.
You cannot modify the plug-in port for the vSphere host.
The default VMware vSphere vCenter port is 443. This port is for communication between the SnapCenter Plug-in for VMware vSphere web client GUI and vCenter.
If you modified a SnapCenter Plug-in for VMware vSphere port, you must log out of the VMware vSphere web client in vCenter and log in again to allow vCenter to update the plug-in.
