Configuring APPN Over Dial on Demand Circuits

APPN is supported over dial on demand circuits for the following DLC types:

v

APPN/PPP/ISDN

v

APPN/FR/ISDN

v

APPN/PPP/V.25 BIS

v

APPN/PPP/V.34

Refer to the

Software User’s Guide for additional information about dial on demand

circuits.

PU 2.1 Node Considerations

When configuring an APPN link station for PU 2.1 nodes over a Dial on Demand
link, you should specify yes for the

limited resource link station parameter. This

allows APPN to:

v

Consider this link as a viable link to be used for route computation, even though
the link is not actually active. The link will automatically become active during
LU-LU session activation for a session needing to use it.

v

Deactivate the link station when there are no active sessions using this link.

You should not configure CP-CP sessions over a dial on demand link. CP-CP
sessions are persistent sessions. That is, they should remain active as long as the
link is active. Since the active session count will not go to zero in this case, the link
will remain active.

Note: If you specify yes for the

limited resource parameter for a PU 2.1 node, you

must specify an adjacent CPNAME and a TG number in the range of 1 to
20.

PU 2.0 Node Considerations

When configuring an APPN link station for PU 2.0 nodes over a Dial on Demand
link, you can specify yes for the

limited resource link station parameter. This allows

APPN to deactivate the link station when there are no active sessions using it.

Note: If

limited resource is yes, link activation for this link station must be initiated

by either the DSPU (the PU 2.0) or by VTAM.
