Library /sys$common/syshlp/ncphelp.hlb SET, EXECUTOR, STATE node-state  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Specifies the operational state of the local node.  There are four
 possible states:

   OFF          Allows no new logical links, terminates existing
                links, and stops route-through traffic.

   ON           Allows logical links.

   RESTRICTED   Allows no new inbound links from other nodes.

   SHUT         Allows no new logical links, does not destroy
                existing links, and goes to the OFF state when
                all logical links are disconnected.
