Specifies whether the adjacent node is expected to be a network
node. If a value for the NN operand is specified, it will be validated
when a connection is attempted to the adjacent node. If the adjacent
CP is not the type of node that is expected, then connection setup
fails. If the NN operand is not specified, then the APPN capabilities
of the adjacent node are identified and accepted when a connection
is established.
- NN=NO
- Specifies that the adjacent node is expected to be an end node.
- NN=YES
- Specifies that the adjacent node is expected to be a network node.
Restriction: In a peripheral subnetwork boundary configuration between a border node and a network node without border node function, the border node appears to the non-border node as an end node. In this case, coding NN=YES on the definition statement that represents the border node, a connection failure will occur. Avoid the failure by not coding the NN operand or by coding NN=NO.
