The DISPLAY ROUTE command provides information about what routes are available between the VTAM® host node and a destination subarea node. In addition, the TEST operand of the DISPLAY ROUTE command allows the operator to test the explicit routes between the host node and a destination subarea node for the routes' ability to transfer data between the subareas. The routes to be displayed can be specified by explicit route number, virtual route number, or Class of Service name. If the TEST operand is specified and the routes to be displayed are specified by virtual route number, the explicit routes tested are those to which the specified virtual routes are currently mapped. If the TEST operand is specified and the routes to be displayed are specified by Class of Service, the explicit routes tested are those to which the virtual routes in the specified Class of Service are currently mapped.

You can also test explicit routes starting in an NCP. The ORIGIN operand on the DISPLAY ROUTE command specifies the NCP in which the route starts. Although the originating node must be NCP Version 3 or later, the subarea at the other end can be any of the products that can coexist with VTAM Version 3 or subsequent releases.
