Modifying plug-in ports

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.

About this task

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:

Note: The following limitations apply to vSphere hosts only:
  • SnapCenter port modifications

    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.

  • vCenter port modifications not supported

    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.
