statements:

dependencies:

APPN only

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.

Note: If the TRLE operand is coded, NN is ignored. See TRLE for more information.

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.
