A VARY INACT command for an NCP major node can result in the automatic deactivation of cross-subarea links and link stations in adjacent subarea nodes (other NCPs or VTAM® itself). For example, if the operator enters a command to deactivate an NCP, VTAM automatically deactivates any links and link stations that were automatically activated in adjacent nodes, provided these adjacent links and link stations were not also directly or indirectly activated.

VTAM does not automatically deactivate a multipoint subarea link, even if all physical units on the line have been deactivated.
