SUMMARY
This article describes how to configure SNA Server to talk to a remote IBM AS/400 computer, connected as follows:  SNA Server <--->  AS/400  <- (appn) ->  AS/400 (SNASERV)       (AS400A)              (AS400B) For users to connect to AS400B through SNA Server, SNA Server should be configured with two Remote APPC LU's (AS400A and AS400B) off a single 802.2 connection to AS400A. Users can then open sessions to AS400B by requesting the AS400B remote LU name.

For additional information and configuration examples showing how SNA Server can be configured to communicate with an AS/400, please see the following articles in the Microsoft Knowledge Base:

112158 Configuring SNA Server to Talk to AS/400 Over 802.2

112159 Configuring SNA Server to Talk to AS/400 Over SDLC

NOTE: SNA Server should only be configured with a single 802.2 connection to an AS/400. SNA Server dual connections to the same AS/400 will not work, since the AS/400 only supports a single APPC controller definition per control point, and SNA Server (acting as a LEN node) can only be configured with a single local control point name.



MORE INFORMATION
In some network configurations, it may not be practical for SNA Server to have a direct SNA link to an AS/400. In cases where a remote AS/400 is accessible through a locally accessible AS/400 acting as an APPN network node, SNA Server can be configured to access the remote AS/400.

Referring to the diagram above, here is how SNA Server could be configured to support user access to both AS/400's. Using an 802.2 connection as an example:   Server Properties Local network name       = APPN Local control point name = SNASERV

Local APPC LU Properties: SNASERV LU 6.2 type = Independent LU alias           = SNASERV network name       = APPN LU name            = SNASERV

Connection Properties: TOKEN1 Remote end = peer system Remote network address   = < address of AS400A > Remote network name      = APPN Remote control point name = AS400A

Remote APPC LU Properties: AS400A  (used to access AS400A) LU alias           = AS400A network name       = APPN LU name            = AS400A Supports parallel sessions

Partners: Partner LU = SNASERV, Mode = QPCSUPP, Connection: TOKEN1

Remote APPC LU Properties: AS400B  (used to access AS400B) LU alias           = AS400B network name       = APPN LU name            = AS400B Supports parallel sessions

Partners: Partner LU = SNASERV, Mode = QPCSUPP, Connection: TOKEN1 To open a session to AS400B, the SNA Server user should request Local LU alias of SNASERV, and a remote LU alias of AS400B.
