When you create an OpenVMS Cluster or OpenVMS Node object
in an OpenVMS Management Domain, you select the transport you want
to use for all connections to that system. You can choose DECnet
Phase IV for OpenVMS or TCP/IP.
OpenVMS Management Station uses this transport for all communications
between the PC and this system, or between any other OpenVMS system
that is running the OpenVMS Management Station server and this system.
The OpenVMS Management Station client supports only
TCP/IP connections for primary servers. That is, the connection
between the PC and the OpenVMS system uses only TCP/IP. Therefore,
at least one OpenVMS system must be running
TCP/IP.
You do need to make sure that your PC can connect to the primary-server
systems, as described in the following sections. OpenVMS Management
Station connects your PC to the primary-server system and then routes
management operations to the target systems.
