/CONNECTIONS=option

    Allows you to specify the type of connections permissible on the
    local node. The four options for CONNECTIONS are:

    INCOMING_      Specifies that the local node permit incoming
    ONLY           connections only.
    OUTGOING_      Specifies that the local node permit outgoing
    ONLY           connections only. Specify this on systems that
                   can tolerate the overhead associated with outgoing
                   connections, such as standalone systems.
    BOTH           Specifies that the local node permit both incoming
                   and outgoing connections. Specify this on systems
                   that can tolerate the overhead associated with
                   outgoing connections, such as standalone systems.
    NONE           Specifies that the local node disallow both
                   incoming and outgoing connections.

    If you do not specify the /CONNECTIONS=option qualifier, the
    default is that the node will permit incoming connections only.
