Configuring X.25 Services

B-6 117377-A Rev. A

Endpoint QLLC Network

Figure B-3 shows support for a network that connects an upstream X.25-attached

SNA end station, and a downstream X.25-attached SNA end station. The end

stations can be an AS 400 and a PC supporting a hierarchical protocol such as

SNA or a peer-to-peer protocol such as APPN.

Setting the Options Parameter

Set the Options parameter to Don’t Wait when both end stations are X.25/QLLC

devices.
