APPC Subsystem Conﬁguration

Conﬁguration Illustrations

The APPC subsystem is using three SNA nodes on the HP 3000:

HOSTPU, AS4001, and AS4002. Each connection to a remote system

requires a separate conﬁgured SNA node and a separate copy of

SNA/SDLC Link/XL.

Independent LU HPINDLU1 on the HP 3000 is conﬁgured to

communicate with two independent LUs on AS/400 #1: GREENLU and

BLUELU. One session type is conﬁgured for each remote independent LU.

The other independent LU on the HP 3000, HPINDLU2, uses the

intermediate routing capabilities of AS/400 #2 to communicate with

independent LU PURPLELU on AS/400 #3. AS/400 #3 is not directly

connected to the HP 3000, and it resides in a different network. The

Fully Qualified Remote LU Name conﬁgured for HPINDLU2 tells

AS/400 #2 the network location of the destination LU, PURPLELU.

The dependent LU session type using HOSTPU has a limit of 4 active

sessions. Two of them are conﬁgured for automatic activation, so the

illustration shows two sessions active between the LUs on the HP 3000

and the LUs on the IBM host.

See Appendix B , “Sample Conﬁguration,” for sample SNA node

conﬁguration screens and APPC conﬁguration screens for the example

in Figure 4-19.
