Conﬁguring DLUR

Note

You cannot conﬁgure passthrough DLUR on an end node.

The tasks you need to perform to conﬁgure DLUR depend on whether the dependent LUs are on the local node or

on downstream nodes.

To conﬁgure DLUR support on the local node, you must perform the following conﬁguration tasks:

1. Deﬁne the local node as described in Section 4.2,

Conﬁguring the Node. If you are providing passthrough

DLUR support for downstream nodes, deﬁne the node as an APPN network node.

2. Conﬁgure connectivity to the APPN network. APPN connectivity requires at least a port and link station for

independent trafﬁc between the local node and the adjacent APPN network node, as described in Chapter 5,

Deﬁning Connectivity Components.

3. Deﬁne a DLUR PU on the local node as described in Section 5.3, Deﬁning DLUR PUs. (The DLUR PU supports

connectivity to the host.)

4. To conﬁgure DLUR to support LUs on the local node, you must add the LUs on the local node, as described

in Chapter 8, Conﬁguring User Applications. The LUs can be conﬁgured to support 3270 display, 3270 printer,

RJE, or LUA. Depending on the requirements of the user applications supported by the LUs, you may also need

to perform further conﬁguration.

To conﬁgure passthrough DLUR support for downstream nodes, you must perform the following conﬁguration tasks:

1. Deﬁne the local node as an APPN network node (see Section 4.2, Conﬁguring the Node).

2. Conﬁgure connectivity to the downstream nodes. Conﬁgure ports and link stations for dependent trafﬁc between

the local node and each downstream node, as described in Chapter 5, Deﬁning Connectivity Components.(You

do not need to deﬁne a DLUR PU to support DLUR for downstream nodes.)

3. A downstream node can support multiple PUs. In this case, each downstream PU is associated with a differ-

ent link, so you need to conﬁgure multiple links between the SNAplus2 DLUR node and the downstream node,

and you need to know the downstream PU name for each link.
