/sys$common/syshlp/helplib.hlb SHOW, INTRUSION, Qualifiers, /NODE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /NODE[=(node-name[,...])]

    The /NODE qualifier displays each intrusion record with the
    supporting node information.

    If you specify individual nodes, the supporting node information
    is displayed only for the nodes listed.
